Forms Data Controls :: Index Was Out Of Range - Must Be Non-negative And Less Than The Size Of The Collection
May 20, 2010
This is my first attempt at paging on a listview. The first time my page loads it loads the listview fine, but when I try to use the paging I get the following error:
Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index
Here's my code:
[code].....
When I take the following line out I don't get the error, but i need it to populate my controls:
DataKey currentDataKey = this.lvReports.DataKeys[currentItem.DataItemIndex];

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" .

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.

I have used the DataKeyNames property of the GridView to assign the column name whose visible property is set to false to get the cells value when the column is kept invisible. But, sometimes there is an error on this line of code - string cellValue = GridView.DataKeys[e.NewEditIndex].Value.ToString(); Following Error is generated -

A dataview is throwing an out of range exception when a page submit button is clicked. The strange part is if you change the data in the dataview by selecting a different person in the DDL the page works fine. Its only when the page loads and the default person in the DDL is when the DataView throws the exception.
The exception is thrown on the last line when I add DV.Rows(0).Cells(1).Text to the id_num parameter. I know there is a value in the dataview because it is displayed on the page. I can refresh the dataview with another person's information and the code works fine. This really has me confused. Here is a bit of the code behind.
Dim dashDataSource
As
New
SqlDataSource()
dashDataSource.ConnectionString =
ConfigurationManager.ConnectionStrings("SSSConnectionString2").ToString()
dashDataSource.InsertCommandType =
SqlDataSourceCommandType.Text
dashDataSource.InsertCommand =
"INSERT INTO tblAcadReferrals(all columns and parameter info here)"
dashDataSourceInsertParameters.Add("id_num", DV.Rows(0).Cells(1).Text)
