currently this method is displaying in a gridview2 just the first column of the rows checked in gridview1 checkboxes but i need to display all of the columns exactly as gridview1, so how do i do it?
protected void Button1_Click2(object sender, EventArgs e)
{
List<string> lista = new List<string>();
for (int i = 0; i < GridView1.Rows.Count; i++)
{
CheckBox chbox = GridView1.Rows[i].Cells[0].FindControl("chk") as CheckBox;
if (chbox.Checked == true)
{
lista.Add("'" + GridView1.Rows[i].Cells[1].Text + "'");
}
}
DataTable dt = new DataTable();
GridView2.DataSource = lista;
GridView2.DataBind();
}
code to of your button will be below
protected void Button1_Click2(object sender, EventArgs e)
{
List<CopyGrid> lista = new List<CopyGrid>();
for (int i = 0; i < GridView1.Rows.Count; i++)
{
CheckBox chbox = GridView1.Rows[i].Cells[0].FindControl("chk") as CheckBox;
if (chbox.Checked == true)
{
CopyGrid content = new CopyGrid();
content.Name = GridView1.Rows[i].Cells[1].Text;
content.Email = GridView1.Rows[i].Cells[2].Text;
content.City = GridView1.Rows[i].Cells[3].Text;
content.PostCode = GridView1.Rows[i].Cells[4].Text;
lista.Add(content);
}
}
// DataTable dt = new DataTable();
GridView2.DataSource = lista;
GridView2.DataBind();
}
also create one class that will store details of gridview1
public class CopyGrid
{
public string Name;
public string Email;
public string City;
public string PostCode;
}
This is just sample code you have to implement your own code.

Why do it when the row is data bound? Why not do it when you originally bind the data?
protected void Page_Load(object sender, EventArgs e)
{
if(!IsPostBack)
{
DataTable dt = Database.GetData();
GridView1.DataSource = dt;
GridView1.DataBind();
//calculate here by manually adding up the debit/credit column from dt
//or do a separate database call that calculates the sum, ex: select sum(debits), sum(credits) from general_ledger
}
}
It makes sense to let the database do the math calculation for you. You wouldn't need to write your own custom calculation code. Just let the database's sum function handle it.
Here's a little more detail.
//Executes a SqlCommand and returns a DataTable
public class GetDataTable(SqlCommand command)
{
var dt = new DataTable();
using (var connection = new SqlConnection("connectionstring"))
{
command.Connection = connection;
connection.Open();
dt.Load(command.ExecuteReader());
}
return dt;
}
//Executes a SqlCommand and returns a scalar of type T
public static T GetScalar<T>(SqlCommand command)
{
using (var connection = new SqlConnection ("connectionstring"))
{
command.Connection = connection;
connection.Open();
var result = command.ExecuteScalar();
if (result is T)
{
return (T)result;
}
else
{
return (T)Convert.ChangeType(result, typeof(T));
}
}
}
//Load the data into the GridView, then get the credit amount and put the value in a label.
//You'll need to adjust the queries to match your schema
protected void Page_Load(object sender, EventArgs e)
{
if(!IsPostBack)
{
var tableCommand = new SqlCommand("select columns from table");
GridView1.DataSource = GetDataTable(tableCommand);
GridView1.DataBind();
var creditCommand = new SqlCommand("select sum(stat_amount) from tablename where stat_flag='c'");
var credits = GetScalar<decimal>(creditCommand);
Label1.Text = credits;
}
}
I have a DropDownList which has a list of tables. Under it there is GridView. Based on the table selected from the drop down list box, I will populate the GridView dynamically. Since the tables could have different column names, I need to create the template field for the GridView dynamically.
Following is my bind method. I have two problems:
I couldn’t wrap the binding part in if (!IsPostBack) since the GridView is populated based on the selection of the DropDownList, so everytime I change the selection, the columns will be duplicated.
And I don’t have any data, I think I need to set ItemTemplate of the tField (TemplateField), but how do I do that?
My bind method
private void BindGridView()
{
DataSet ds = new DataSet();
try
{
ds = …
if (ds.Tables.Count > 0)
{
foreach (DataColumn dc in ds.Tables[0].Columns)
{
TemplateField tField = new TemplateField();
tField.HeaderText = dc.ColumnName;
GridView2.Columns.Add(tField);
}
GridView2.DataSource = ds.Tables[0];
GridView2.DataBind();
}
else
{
…
}
}
catch (Exception ex)
{
…
}
}
There are various steps that should be taken care of:
STEP I::
Create a class inheriting the ITemplate interface. Override the method InstantiateIn() of the ITemplate interface.
STEP II:
Define a constructor for your class that takes a ListItemType object as its parameter.
STEP III::
If the Control being added to the container's ControlCollection has to be bound to some DataSource Column, then register the
handler for the OnDataBinding event. When the event occurs, retrieve the text from the data source and assign it to your control. For Example, hyprLnk_DataBinding event is defined for Binding Data to your controls created inside ItemTemplate.
public class TemplateGenerator : ITemplate // Class inheriting ITemplate
{
ListItemType type;
string columnName;
public TemplateGenerator(ListItemType t, string cN)
{
type = t;
columnName= cN;
}
// Override InstantiateIn() method
void ITemplate.InstantiateIn(System.Web.UI.Control container)
{
switch (type)
{
case ListItemType.Item:
HyperLink hyprLnk = new HyperLink();
hyprLnk.Target = "_blank"; //Optional.
hyprLnk.DataBinding+=new EventHandler(hyprLnk_DataBinding);
container.Controls.Add(hyprLnk);
break;
}
}
// The DataBinding event of your controls
void hyprLnk_DataBinding(object sender, EventArgs e)
{
HyperLink hyprlnk = (HyperLink)sender;
GridViewRow container = (GridViewRow)hyprlnk.NamingContainer;
object bindValue = DataBinder.Eval(container.DataItem,columnName);
// Adding check in case Column allows null values
if (bindValue != DBNull.Value)
{
hyprlnk.Text = bindValue.ToString();
hyprlnk.NavigateUrl = "http://www.google.com";
}
}
}
That's all. Above was just a sample to create ItemTemplate dynamically for GridView and add controls to the Item Template.
Now, Below is the function that will actually carry out the calls to create Template Columns dynamically. You can call this function when required for e.g. from your DropDownList event Handler.
protected void GenerateGridViewColumnsDynamically()
{
// Create the TemplateField
TemplateField firstName = new TemplateField();
firstName.HeaderText = "First_Name";
firstName.ItemTemplate = new TemplateGenerator(ListItemType.Item, "FirstName");
// Showing boundField example just for more context
BoundField lastName = new BoundField();
lastName.DataField = "LastName";
lastName.HeaderText = "Last_Name";
// Add the Columns now
MyGridView.Columns.Add(firstName);
MyGridView.Columns.Add(lastName);
}
NOTE:: FirstName and LastName are the Columns whose Names are passed to the constructor of your custom class: TemplateGenerator.
I have done the same functionality as below with custom paging(using storedProc) for 100+ million records in many tables, update, delete and insert also:
CREATE PROCEDURE [dbo].[sp_Mk]
#PageIndex INT,
#PageSize INT,
#tableName nvarchar(255),

Hope it helps:
I have a list in my SharePoint site with name "Empdetails" and having columns (EmpName string, Empaddress string).
I have to bind the list data to the SpGridview with edit, delete, update functionality.
I am able to bind the list data to gridview successfully, but I am unable to provide edit, delete, update functionality to the gridview.
Code:
private void binddata()
{
SPWeb mySite = SPContext.Current.Web;
SPList myList = mySite.Lists["Empdetails"];
SPListItemCollection items = myList.Items;
//Here we will make a datatable and we will put our list data to the data table
DataTable table=new DataTable();
table.Columns.Add("EmpName", typeof(string));
table.Columns.Add("Empaddress", typeof(string));
// Create rows for each splistitem
DataRow row;
foreach (SPListItem result in items)
{
row = table.Rows.Add();
row["EmpName"] = result["EmpName"].ToString();
row["Empaddress"] = result["Empaddress"].ToString();
}
//binding data to gridview
GridView1.DataSource = table.DefaultView;
GridView1.DataBind();
}
You will need to write all of the code for updates and deletes. It is not provided automatically.
Personally, I would recommend using the out of the box List View web part that points to a Datasheet view rather than trying to create my own.
But if you must write custom code, your code above might be able to be simplified from this:
DataTable table = new DataTable();
table.Columns.Add("EmpName", typeof(string));
table.Columns.Add("Empaddress", typeof(string));
DataRow row;
foreach (SPListItem result in items)
{
row = table.Rows.Add();
row["EmpName"] = result["EmpName"].ToString();
row["Empaddress"] = result["Empaddress"].ToString();
}
to this:
DataTable table = items.GetDataTable();
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
Bindata();
}
}
public void Bindata()
{
SPWeb web = SPContext.Current.Web;

DataTable dt = new DataTable();
dt.Columns.Add("Title", typeof(string));
foreach (SPListItem item in list.Items)
{
DataRow dr = dt.NewRow();
dr["Title"] = item["Title"].ToString();
dt.Rows.Add(dr);
}
GridView1.DataSource = dt;
GridView1.DataBind();
}

Hi i added template field dynamically to gridview by implementing ITemplate interface.
The template field contains some controls like label and textboxes. how do i get these controls in row databound event.
I am not able to get when i do gridviewrow.findcontrol("id") as i do normally when we add templatefield from aspx page.
The way i added template field is like this
public class CustomGridViewColumn : ITemplate
{
ListItemType _liType;
string _columnName;
public CustomGridViewColumn(ListItemType type, string column)
{
_liType = type;
_columnName = column;
}
void ITemplate.InstantiateIn(System.Web.UI.Control container)
{
switch (_liType)
{
case ListItemType.Header:
Label lblHeader = new Label();
lblHeader.Text = _columnName;
container.Controls.Add(lblHeader);
break;
case ListItemType.Item:
Label lblItem = new Label();
lblItem.DataBinding += new EventHandler(lbl_DataBinding);
lblItem.ID = "lbl" + _columnName;
lblItem.ClientIDMode = ClientIDMode.Predictable;
container.Controls.Add(lblItem);
DropDownList ddl = new DropDownList();
ddl.DataBinding += new EventHandler(ddl_DataBinding);
ddl.ID = "ddl" + _columnName;
ddl.Visible = false;
container.Controls.Add(ddl);
break;
}
}
}
Now i want access the label and dropdown which i have added using this code.
when i do gridviewrow.findcontrol("id") i am not getting them.
Can any one please help me.
I am geeting when i go through all the rows and try to find but
i have a check box in a row when i select it all labels should diappear and ddls dhould appear
for this i am using the follwoing code.
protected void chkEdit_CheckedChanged(object sender, EventArgs e)
{
CheckBox chkEditTest = (CheckBox)sender;
GridViewRow grow = (GridViewRow)chkEditTest.NamingContainer;
DropDownList ddl = (DropDownList)grow.FindControl("ddl");
Label lbl= (Label)grow.FindControl("lbl");
}
when i do this i am not able to get the controls.
it seems like controls are disapppearing on postback..
This is what I came up with and I can able to get the control reference in the code behind.
public class CustomGridViewColumn : ITemplate
{
ListItemType _liType; string _columnName;
public CustomGridViewColumn(ListItemType type, string column)

Can you try using row index of GRIDVIEW control
var rowIndex = int.Parse(e.CommandArgument)
GridView1.Rows[rowIndex].FindControl("id")

I would like somebody to help me to solve the following issue.
I have a gridview, where the fields are created dynamically from codebehind.
I would like to create with the same way(dynamically) a templateField which, if it is possible, to hold in it two button controls, having also and commandName.
To be more clear:
Headers-->> First Name, LastName, Print(Daily/Invoices)
Results -->> FooFName, FooLName, Daily | Invoice
The bold one text is what I am looking for.
I am posting also the methods and the way I use them to create the fields.
CreateBoundField(BillingSummaryGV, "Book_Date", "Date", "{0:dd/MM/yyyy}");
CreateButtonField(BillingSummaryGV, "Print", "Print(Daily)", ButtonType.Link,"");
BillingSummaryGV.DataSource = billingSummaries;
BillingSummaryGV.DataBind();
protected void CreateBoundField(GridView gv, string dataField, string headerText, string arrFormatingString) {
var bf = new BoundField {
DataField = dataField,
DataFormatString = arrFormatingString,
HeaderText = headerText
};
gv.Columns.Add(bf);
}
private void CreateButtonField(GridView gv, string text, string headerText, ButtonType buttonType, string commandName) {
var bfPrint = new ButtonField() {
ButtonType = buttonType,
Text = text,
HeaderText = headerText,
Visible = true,
CommandName = commandName
};
gv.Columns.Add(bfPrint);
}
I would appreciate any reply
thanks
You have to create a template class that implements ITemplate. See this example from MSDN. The code below extends my answer to this question to add a template column that displays Title|Author.
Markup:
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="false"
OnRowCommand="GridView1_RowCommand"
OnRowEditing="GridView1_RowEditing"/>
Code:
protected void Page_Load(object sender, EventArgs e)
{
BindGridView();
}
private DataTable GetBooksDataTable()
{
var dt = new DataTable();
dt.Columns.Add("ID", typeof(int));
dt.Columns.Add("Title", typeof(string));
dt.Columns.Add("Author", typeof(string));
for (int index = 0; index < 10; index++)
{
dt.Rows.Add(index, "Title" + index, "Author" + index);
}
return dt;
}
private void BindGridView()
{
var dt = GetBooksDataTable();
GridView1.Columns.Clear();
