Error - Index Out Of Range Exception When Storing Into .net Session?
Oct 7, 2010
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;
Session[1] = ddlState.SelectedValue;
Session[2] = txtActingSupervisor.Text;
Session[3] = ddlRiskTolerance.SelectedValue;

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 -
Server Error in '/' Application. Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

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)

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 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.
