I'm trying to throw the exception back to Page_Load but the throw statement causes error: ArgumentNullException was unhandled by user code. How can that be fixed? Also, I can't see Label1.Text displayed on the page after the ArgumentNullException occurs because the page is not re-load. If there is no exception, it's fine to not reload the page. How can I see the Label1.Text displayed?
protected void Page_Load(object sender, EventArgs e)
{
try
{
...do something here...
}
catch (ArgumentNullException ae)
{
System.Diagnostics.Debug.Write(ae.Message);
Label1.Text = ae.Message;
Label1.Style.Add("visibility", "visible");

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'm working on having two forms that communicate together. In order to do this, I am passing public value from the source page. Here's how I did it:
In the source page I have:
Public ReadOnly Property CurrentCity() As String
Get
Return txtboxfake.Text
End Get
End Property
Then under page_load of the page I have:
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
txtteam.Text = PreviousPage.CurrentCity
txtboxdate.Text = Calendar1.SelectedDate
End Sub
For some reason I keep getting an error that says "NullReference exception unhandled by user code" that points to txtteam.text = PreviousPage.CurrentCity.
I did executed a db - contact form page successfully in the same project with the same connection string, but for this page its doing error and so I commented the binary file saving codes and all and put just simple 2 fields to see if the db is connecting and surprisingly getting sqlexception error and no data is written to the db.

View 6 RepliesA 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.

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 downloaded a sample Rolodex from here: [URL] the file to download is at the bottom of the page and it is called 'RolodexDatalist.zip (6.71 kb)' So I changed the HTML to it points to my SQL Server DB. I changed the ConnectionString to this:

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.
