I currently am using a listview to edit and update data. When I click edit it goes into the edit format that I want it to. I want to be able to exit the entire edit mode after the update button is clicked. Is this possible?
When I use ListView1.EditIndex = -1 it doesn't go back to the regular view.
protected void ListView1_ItemUpdating(object sender, ListViewUpdateEventArgs e)
{
updateButton = true;
ListViewItem lvl = ListView1.Items[e.ItemIndex];
var formTitleListBox = (ListBox)lvl.FindControl("ListBox1");
var controlTypeListBox = (ListBox)lvl.FindControl("ControlType");
var formSectionListBox = (ListBox)lvl.FindControl("formsection");
var sortOrderTextBox = (TextBox)lvl.FindControl("SortOrderTextBox");
var subsectionListBox = (ListBox)lvl.FindControl("subsection");
var subSectionTextBox = (TextBox)lvl.FindControl("SubSectionOrderTextBox");

var sectionSortOrderTextBox = (TextBox)lvl.FindControl("SectionSortOrderTextBox");
var validationRuleListBox = (ListBox)lvl.FindControl("RuleDesc");
var crossItemListBox = (ListBox)lvl.FindControl("CrossItem");
var hiddenID = (HiddenField)lvl.FindControl("HiddenPrimaryID");
using (SqlConnection connection = new SqlConnection("Data Source=RCK-HRSA-DB01;Initial Catalog=ORHP_Dev03182014;User ID=ohitrural;Password=0h!trural"))

I want to select multiple item from checkbox list and then fill another check Box list on select index changed event of First check box list but after one selection its not working for another selected items because of "Auto Post Back = true" while debbuging i can see pointer start from page load event. I want after selection of all Item it should be fire "ddlregion_SelectedIndexChanged" so that I can able see all selected Item related value in another check Box List.
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
BindRegion();
}
}
Due to this its not fetching data for another selected Items how to solve this issues Please help me.

You need to build your region list for the SQL, then once done call your SQL and Bind.
string regions = "";
bool regionSelected = false;
foreach (ListItem item in ddlregion.Items)
{
if (item.Selected == true)
{
regions += item.SelectedValue + ",";
regionSelected = true;
}
}
// looping done so clean up string for SQL
regions = "(" + regions.TrimEnd(',') + " )";
//only run if a region is selected
if(regionSelected)
{
string str = "select d.depot_code, d.depot_description from regions r, sub_regions sr,
depots d where r.region_code = sr.region_code and
sr.sub_region_code = d.sub_region_code and active = 'Y' and r.region_code
in " + regions;
OracleCommand Cmd = new OracleCommand(str, con);
Cmd.CommandType = CommandType.Text;
OracleDataAdapter da = new OracleDataAdapter();
DataSet ds = new DataSet();
da.SelectCommand = Cmd;
da.Fill(ds);
ddlDepot.DataSource = ds;
ddlDepot.DataTextField = "DEPOT_DESCRIPTION";
ddlDepot.DataValueField = "DEPOT_CODE";
ddlDepot.DataBind();

I have a method that reads data from a database table using SqlDataReader.
i assign data retrieved by SqlDataReader into a List and return it.
when i want to assign the List data from method into the List on Code behind file,
i encounter the following error:

and it is working now ....
I am getting this error "Must Declare the scalar variable "Post_ID" if i try to update 2 different ID's in my table. In other words, i can update as many times as i need to for example ID # 25 but if i try to update ID # 26 then i get the error above. My insert function works fine only my update function. Pls. help and i appreciate your time. Note, the DateKeyNames = ID. Here is my code for the update only:
SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["MyConnectionString"].ConnectionString);
SqlCommand cmd = new SqlCommand();
cmd.CommandText = "UPDATE MyTable SET Post_ID=#Post_ID, Date=#Date, Description=#Description WHERE ID=#ID";
TextBox myTextBox11 = GV_InlineEditing.Rows[0].FindControl("GV_Post_ID") as TextBox;
TextBox myTextBox22 = GV_InlineEditing.Rows[0].FindControl("TextBox2") as TextBox;
TextBox myTextBox33 = GV_InlineEditing.Rows[0].FindControl("TextBox3") as TextBox;
if (myTextBox11 != null)
{
cmd.Parameters.Add("#Post_ID", SqlDbType.VarChar).Value = myTextBox11.Text;
}
else
{
TextBox GV_Post_ID = GV_InlineEditing.Rows[0].Cells[0].FindControl("GV_Post_ID") as TextBox;
}
if (myTextBox22 != null)
{
cmd.Parameters.Add("#Date", SqlDbType.VarChar).Value = myTextBox22.Text;
}
else
{
TextBox GV_Post_ID = GV_InlineEditing.Rows[0].Cells[0].FindControl("Date") as TextBox;
}
if (myTextBox33 != null)
{
cmd.Parameters.Add("#Description", SqlDbType.VarChar).Value = myTextBox33.Text;
}
else
{
TextBox GV_Post_ID = GV_InlineEditing.Rows[0].Cells[0].FindControl("Description") as TextBox;
}
cmd.Parameters.Add("#ID", SqlDbType.Int).Value = Convert.ToInt32(GV_InlineEditing.Rows[e.RowIndex].Cells[1].Text);
cmd.Connection = con;
con.Open();
cmd.ExecuteNonQuery();
con.Close();
}
GV_InlineEditing.EditIndex = -1;
BindData();
Your logic is somewhat faulty:
if (myTextBox11 != null)
{
//add paramter
cmd.Parameters.Add("#Post_ID", SqlDbType.VarChar).Value = myTextBox11.Text;
}
else
{
//declare a different textbox and do not add the SQL parameter
TextBox GV_Post_ID = GV_InlineEditing.Rows[0].Cells[0].FindControl("GV_Post_ID") as TextBox;
}
This pattern is repeated for myTextBox22 and myTextBox33.
I would suggest this logic instead:
SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings("MyConnectionString").ConnectionString);
SqlCommand cmd = new SqlCommand();
cmd.CommandText = "UPDATE MyTable SET Post_ID=#Post_ID, Date=#Date, Description=#Description WHERE ID=#ID";
TextBox myTextBox11 = GV_InlineEditing.Rows(0).FindControl("GV_Post_ID") as TextBox;
TextBox myTextBox22 = GV_InlineEditing.Rows(0).FindControl("Date") as TextBox;
TextBox myTextBox33 = GV_InlineEditing.Rows(0).FindControl("Description") as TextBox;
if (myTextBox11 == null) {
//try an alternate control for myTextBox11
myTextBox11 = GV_InlineEditing.Rows(0).Cells(0).FindControl("GV_Post_ID") as TextBox;
}
if (myTextBox22 == null) {
//try an alternate control for myTextBox22
myTextBox22 = GV_InlineEditing.Rows(0).Cells(0).FindControl("Date") as TextBox;
}
if (myTextBox33 == null) {
//try an alternate control for myTextBox33
myTextBox33 = GV_InlineEditing.Rows(0).Cells(0).FindControl("Description") as TextBox;
}
if (myTextBox11 != null & myTextBox22 != null & myTextBox33 != null) {
//all three textbox controls found
cmd.Parameters.Add("#Post_ID", SqlDbType.VarChar).Value = myTextBox11.Text;
cmd.Parameters.Add("#Date", SqlDbType.VarChar).Value = myTextBox22.Text;
cmd.Parameters.Add("#Description", SqlDbType.VarChar).Value = myTextBox33.Text;
cmd.Parameters.Add("#ID", SqlDbType.Int).Value = Convert.ToInt32(GV_InlineEditing.Rows(e.RowIndex).Cells(1).Text);
cmd.Connection = con;
con.Open();
cmd.ExecuteNonQuery();
con.Close();
}
UPDATE
Add else conditions to Throw New Exception("myTextBox11 is null"); for myTextBox11, myTextBox22, and myTextBox33.
That will allow you to see if both:
GV_InlineEditing.Rows(0).FindControl("Date") as TextBox;
and:
GV_InlineEditing.Rows(0).Cells(0).FindControl("GV_Post_ID");
are failing.
I always do something like this like this:
protected void Gridview1_RowUpdating(object sender, GridViewUpdateEventArgs e)
{
GridViewRow row = (GridViewRow)GridView1.Rows[e.RowIndex];
int id = Int32.Parse(GridView1.DataKeys[e.RowIndex].Value.ToString());
TextBox date = (TextBox)row.FindControl("date");
SqlCommand cmd = new SqlCommand();
cmd.CommandText = "update t_your_table " +
"set " +
"date = #date, " +
" time = #time where id = #ID "
cmd.Parameters.Add("#id", SqlDbType.VarChar).Value = id;
cmd.Parameters.Add("#date", SqlDbType.VarChar).Value = date.Text;
You have to get your datakeyname into the variables. That way it will use that field no matter what row is clicked.
I have a user control inside a webpart inside sharepoint that I add some linkbuttons dynamically during runtime. each one when clicked is supposed to download a certain file from the database. however when one of those linkbuttons is clicked, this file is downloaded for once and then i can't click any other buttons or links or even the same one again on this user control and webpart. but i can still click other things outside the user control and webpart. do u have any idea? please tell me which part of the code i can add here if you need to check something. thank you :)

the weird thing that it works well when i put the same code in an asp.net page!!
Ahmad,
Check out the following link on the MSDN forums, as I believe the situation is similar (if not identical) to what you're describing:
http://social.msdn.microsoft.com/forums/en-US/sharepointdevelopment/thread/107b2c17-07fe-4a15-ad81-dcb31e1e9c84/
A couple of different approaches/solutions are discusssed.
I hope this helps!
