my gridview is displaying two rows, among whihc i have to validate whether VALID (1) or invalid (0) from dropdown but it throws error but sometimes it doesn't.
ERROR:
Index was out of range. Must be non-negative and less than the size of the collection.\r\nParameter name: index"}
Your grid doesn't always have at least 5 rows so trying to index into the Rows collection causes your out of bounds exception. Looks a little odd to me that you're currently exepcting exactly 5 rows but if you're getting this error it is not the case.
To avoid the error change your code to this:
for (int i = 0; i < GridViewSmsComplaints.Rows.Count; i++)
{
int ID = Convert.ToInt32(GridViewSmsComplaints.Rows[i].Cells[0].Text);

Below is the code where The four columns("Challan Number","Proposal Number","CTS Number" and "Amount") is obtained from Sql-Database, and the ("Land" and "Ward") values are obtained from respective methods. The values obtaines are correct but still the "ChallanGridview" is not getting populated.
The datarow "dr1" gets populated with the correct required values, but the "ChallanGridview" doesn't shows anything.

When I execute this program the Excel part generates and string array: cellValue just fine.
When it inserts into the SQL MDF Database: MDFExcel every cell displays: "System.__ComObject".
How do you display the string value instead of the "System.__ComObject"?
protected void Button1_Click(Object sender, EventArgs e)
{
DataSet ds = new DataSet();
//From Excel
Microsoft.Office.Interop.Excel.Application exlApp = new Microsoft.Office.Interop.Excel.Application();
Microsoft.Office.Interop.Excel.Workbook exlWb = exlApp.Workbooks.Open(#"C:\Users\Optiplex760\Documents\a Excel\ExcelToMDF.xls");
Microsoft.Office.Interop.Excel.Worksheet exlWs= exlWb.Sheets["Sheet1"];
Microsoft.Office.Interop.Excel.Range usedRange = exlWs.UsedRange;
int col = Convert.ToInt32(usedRange.Columns.Count);
int row = Convert.ToInt32(usedRange.Rows.Count);
exlApp.Visible = true;
string[,] cellValue = new string[row + 1, col + 1];
for (int j = 1; j <= row-1; j++)
{
for (int k = 1; k <= col-1; k++)
{
cellValue[j, k] = exlWs.Cells[j+1,k+1].ToString();
}
}
exlWb.Close();
exlWs = null;
exlWb = null;
exlApp.Quit();
exlApp = null;
//To MSSQL
String connStr, cmdStr;
connStr = ConfigurationManager.ConnectionStrings["MDFExceldb"].ConnectionString;
for (int h = 1; h<row; h++)
{
cmdStr = "INSERT INTO [Table1] (col1,col2,col3) VALUES (#col1,#col2,#col3);";
try
{
using (SqlConnection conn = new SqlConnection(connStr))
{
using (SqlCommand cmd = new SqlCommand(cmdStr, conn))
{
conn.Open();
cmd.Parameters.AddWithValue("#col1", cellValue[1, h]);
cmd.Parameters.AddWithValue("#col2", cellValue[2, h]);
cmd.Parameters.AddWithValue("#col3", cellValue[3, h]);
cmd.ExecuteNonQuery();
conn.Close();
cmd.Dispose();
conn.Dispose();
}
}
}
catch (Exception ex)
{
Label2.Text = ex.ToString();
}
}
}
Worksheet.Cells returns a Range and not a single value - and a Range (an RCW object) does not implemented a sensible ToString; thus it defaults to the "System.__ComObject" value shown.
Use the Text property of the Range, eg.
cellValue[j, k] = Convert.ToString(exlWs.Cells[j+1,k+1].Text);
While this should fix the immediate problem, it is also an inefficient process. See this response (using the Value/Value2 property) for how to access the Range values as a 2-dimensional array and reduce excessive range-slicing.
I have created a function which displays a bus seat layout, dynamically. Now after adding all this dynamically created table and cells into a tag, I want to know which imagebutton was clicked.I have also mentioned proper ID to each imagebutton in cell.
public void DisplaySeatLayout(ListBus _listBus) {
//fetching data from database
SeatBUS _seatBUS = new SeatBUS();
DataTable dt = _seatBUS.GetAllSeatByBusRouter(_listBus);
//Layout generation code
ImageButton img ;
HtmlTable table = new HtmlTable();
table.Attributes.Add("runat", "server");
table.Attributes.Add("id", "LayoutTable");
HtmlTableRow [] tr = new HtmlTableRow[] { new HtmlTableRow(), new HtmlTableRow(), new HtmlTableRow(),new HtmlTableRow(),new HtmlTableRow()};
HtmlTableCell tc = null;
int SeatNo=0;
//Getting Total no of seats.
int MaxSeatNo = dt.Rows.Count;
//Iterating datatable
//Displaying labels for displaying column names in the table
for (int columnCounter = 0; columnCounter < 8; columnCounter++){
for (int rowCounter = 0; rowCounter < 5; rowCounter++){
if (SeatNo < MaxSeatNo){
if (rowCounter == 2 && columnCounter < 7){
tc = new HtmlTableCell();
Label lbl = new Label();
lbl.Text = "";
lbl.ID = "lbl " + rowCounter.ToString() + columnCounter.ToString();
tc.Controls.Add(lbl);
tr[rowCounter].Controls.Add(tc);
//reducing seat number for sake of sequence.
}
else{
//adding label in each cell.
tc = new HtmlTableCell();
Label lbl = new Label();
lbl.Text = dt.Rows[SeatNo]["NumberSeat"].ToString();
lbl.ID = "lbl " + rowCounter.ToString() + columnCounter.ToString();
tc.Controls.Add(lbl);
//adding imagebutton in each cell .
img = new ImageButton();
img.Attributes.Add("type", "image");
img.Attributes.Add("id", rowCounter.ToString());
img.CssClass = "seatRightMostRow1";
img.ImageUrl = "../Images/available_seat_img.png";
img.ID = dt.Rows[SeatNo]["NumberSeat"].ToString();
img.Click += new ImageClickEventHandler(Imagebutton_Click);
tc.Controls.Add(img);
tr[rowCounter].Controls.Add(tc);
SeatNo++;
}
}//SeatNo < MaxSeatNo
table.Controls.Add(tr[rowCounter]);
}
seatArranngement.Controls.Add(table);
}
}
this is complete code after suggestion.
function that is displaying dynamic table is inside Page_load
protected void Page_Load(object sender, EventArgs e)
{
_listBusBUS = new ListBusBUS();
_routerBUS = new RouterBUS();
_listBus = new ListBus();
_promoteBUS = new PromoteBUS();
if (!Page.IsPostBack)
{
LoadData();
}
DisplaySeatLayout();
}
Also here i have copied code in prerender
protected override void OnPreRender(EventArgs e)
{
if (MultiView1.ActiveViewIndex == 1)
{
int listBusID = int.Parse(hdlListBusID.Value.ToString());
_listBus = _listBusBUS.GetAllListBusById(listBusID);
litListBusID.Text = _listBus.ListBusID.ToString();
litRouterID.Text = _listBus.RouterID.ToString();
litArrival.Text = _listBus.Arrival.ToString();
litDeparture.Text = _listBus.Departure.ToString();
litPrice.Text = _listBus.Price.ToString();
}
else if (MultiView1.ActiveViewIndex == 2)
{
//original code starts from here
litListBusIDS.Text = litListBusIDS.Text;
litRouterIDS.Text = litRouterID.Text;
litArrivalS.Text = litArrival.Text;
litDepartureS.Text = litDeparture.Text;
litSeat.Text = hdlSeat.Value;// chkSeat.SelectedItem.Text;
litPrices.Text = litPrice.Text;
//hdlSeat.Value = chkSeat.SelectedItem.Text.ToString();
}
else if (MultiView1.ActiveViewIndex == 3)
{
litCustomerNameStep4.Text = txtcustomername.Text;
litSeatStep4.Text = litSeat.Text;
litPriceStep4.Text = litPrices.Text;
}
base.PreRender(e);
}
Also, layout is getting created twice if i click on any imagebutton.
All you have to do is get the value that you already placed inside the "id" attribute.
You can do this inside the Imagebutton_Click even you created:
protected void Imagebutton_Click(object sender, EventArgs e)
{
ImageButton b = sender as ImageButton;
string id = b.Attributes["id"]; // Returns the id
}
I have placed grid view in update panel with first row as empty and it is not bound with any data base. Rather I have bound grid view with data table. Whenever I click on 'Add New Row' button, a new row is created in grid view there by retaining the data field in old rows but my problem is whenever I click on save button, at that time data of first row is not retried but I can get the data that is filled in second row and onwards. I have saved my data table in session and again retrieving it after each post back.
