string[] cwidth = Session["width"].ToString().Split(',');
int colcount = coln.Length;
for (int i = 0; i <= colcount - 1; i++)
{
Gridview1.Columns[i].HeaderText = coln[i].ToString();
int swidth = Convert.ToInt32(cwidth[i]);
Gridview1.Columns[i].HeaderStyle.Width = Convert.ToInt32(cwidth[i]);

I have an array called"List" with 1 item and a gridview "grdWorkingDays" with two columns.
In the First column, I want to display the working days dynamically from the arraylist and in the second column I need to display a dropdown with CL/PL/Halfday(Which has values from a database table and is already written in a method) against each date of array list.
The code is:
int NoOfWorkingDays = List.Count;
for (int j = 0; j < NoOfWorkingDays; j++){
String Date = ((Label)grdWorkingDays.Rows[j].Cells[0].FindControl("lblLeaveType")).Text;
Date = List[j].ToString();
[Code] .....
When I run this, I am getting error as:
"Index was out of range. Must be non-negative and less than the size of the collection." pointing to the 1st row of for loop.
I am struggling with this for past few days and count find what the error is.
FYI, the array count is being calculated correctly as "1" .

HTML:
<asp:RangeValidator ID="RangeValidator1" runat="server" MaximumValue="1" MinimumValue="-1" Text="value between 1 to -1" ErrorMessage="value between 1 to -1" ControlToValidate="TxtY" ValidationGroup="usrvalid"></asp:RangeValidator>
<asp:TextBox ID="TxtY" Text='<%#Eval("Y") %>' runat="server" Width="30%"></asp:TextBox>

I have the following problem, i am using gridview to display some table info,, and during RowDataBound event i am binding another DataList control placed on gridview template column,,, the problem is that the DataBind() event of the gridview gives "Index 1 is either negative or above rows count." error.
I debugged alot,, when you disable the DataList binding it works,, but why the 2 not working together i dont know!!.

gvOff.DataSource = o.ViewData(dCity.SelectedValue);
gvOff.DataBind();
gvOff.Columns[0].HeaderText = "ZZZZZZZZ";
gvOff.Columns[1].HeaderText = "YYYYYYYY";
gvOff.Columns[2].HeaderText = "XXXXXXXX";
Header count is correct.
AutoGenerateColumns: Flase/True ( i tried both)
If i remove the gvOff.Columns[index].HeaderText portions, GridView works fine, but when i put the gvOff.Columns[0].HeaderText, i get the exceptional error.
, i couldn't solve it. If you need further info, inform me.
EDITED:
Hold on! I commented the HeaderText portion and tested
int i = gvOffer.Columns.Count;
I found count is 0 eventhough the columns print out with DataBind()... Why?
NOTE: AutoColumn in this case is set to true. I guess i will have to edit the column
names from DataTable.

I'm stumbling on a basic LinqDataSource insertion problem. For some reason, I cannot insert records. The run-time returns the following error: Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index The mark-up is as follows with the InsertParameters group. Adding or removing the group leads to the same error. (Note that updating works fine):
[Code]....
The events are void (just a convenient way to to troubleshoot). However, the run-time error occurs before the events are fired.

I'm having a problem when trying to add a new row to a grid view when the grid view paging is "2" for example. Basically, when the data I'm trying to add will be on page number two of the grid, the drop down list I'm trying to bind raises an exception saying that the index is out of range.
How can I add a new grid row with paging and how to tell the drop down list that the row it is looking for is no longer 11, but 1 on the second page?

I'm building a web app that to build a report, but there are too many arguments to give each one a name, and I want to save them indexed by numbers so I can handle them with loops later on throughout the application.However, I'm getting an index out of range on the very first session item(0)...as I understand it, I don't have to instantiate a session myself and this should work right?
Session[0] = txtComplianceCaseID.Text;

I recently had to remove a field from my datakey on all three gridview tables. On the top level table the field (ignum) remains as a non key field. On the two lower level tables it was removed completely. Now, the top level gridview opens correctly, but when I click on select this should bring up all the records in the second gridview associated with the selected row in the first gridview, but I get the following error:
[Code]....
I've looked at everything I can thing of and everything looks ok. The tables look good, I've removed all references to the removed field and I've restructured all the code to account for the changes. I'm missing something, but I don't know what. I've gone through debug step by step and the error occurs as I leave the GridView1_SelectedIndexChanged code. It goes down to the End Sub line with no errors, but when I step again it errors out. Here is that section of code.
