I have a Gridview with AutoGenerateColumns= true and AllowSorting=trueBelow is the code snippet I have in RowEditing. This works fine if I dont change the column order in future.Is there a way I can access the headertext and do something like this
If headertext="Start_StateID" Then
dim Start_StateID As Integer = TheRowinEditMode.cells(this headercolumns index).text
end if
[Code]....
I have the following function that translates the header row in a gridview:
[Code]....
When I added sorting to the gridview cell.Text does not work anymore. How can I access the header text in the cell?
I've searched for this problem on Google and also on this forum (and also this forum using Google) so if there is another topic dealing with this I apologize but I couldn't find it! :)
My problem is that when I try to access the HeaderRow property ASP freaks out and gives me the infamous 'Object variable or With block variable not set.'
error. Here is the code in question:
Public Sub gvwResults_DataBound(sender As Object, e As EventArgs) Handles gvwResults.DataBound
gvwResults.HeaderRow.Cells(7).Visible = False
For Each gvr As GridViewRow In sender.Rows
gvr.Cells(7).Visible = False
Next
End Sub
The line 'gvwResults.HeaderRow.Cells(7).Visible = False' is what raises the error. When I remove it, the code works just like expected except that the header row of the 8th column isn't invisible like I'd like it to be.
I'm pulling my hair out here, this is the very last thing that needs to be finished before this app is usable haha. :)
How to get HeaderRow text when sorting is enabled? (Columns are AutoGenerated and the column that I'm trying to access is set to invisible in the RowCreated Event.)
View 3 RepliesI've read a few articles on this, but I keep doing something wrong, and I'm not sure what. I took out all of my customization and just want to add a single header row to the very top of my GridView... Can someone show me how I'm screwing up? This is the code I'm trying to use...

I have tried a few different ways of referring to the GridView table... e.row.parent, gv1.controls[0], etc, but nothing seems to work.
I don't get any errors, just nothing ever shows up when the GridView is rendered. I can't find the code using Firebug to look at the HTML either... what am I doing wrong?
(have also tried using "0" for the rowIndex when creating the new GridViewRow)

I've got a gridview that returns student order history which works just fine. It pulls the StudentId from a hidden field on page load. I have a link button that ADDS AN ORDER when clicked. It calls a stored procedure, inserts the record, then rebinds the gridview and displays the new record at the top of the list.
Problem is when I go to EDIT it, i get this error... "The GridView 'GridViewOrderHistory' fired event RowEditing which wasn't handled." But the interesting thing is the error doesn't occur if I close the browser and reload the page and then click on that new record that was created. Obviously I'm missing something in my code when the new order is created. Here are the 2 subs involved in the process.

I am populating the gridview on the basis of listbox selection . However, I am setting the datasource in the click event after listbox entry. When i am trying to update any record in the gridview this error gets thrown because the datasourceid from the aspx page has been removed. Code for reference -
protected void btn_save_Click(object sender, EventArgs e)
{
ArrayList list = new ArrayList();
foreach (object o in ListBox2.Items)
{
list.Add(o);
}
string str2 = null, str, host;
string str1 = "SELECT SYSTEMNAME, DATETIME, PDOWNTIME, UDOWNTIME, SYSDOWNMINS, REASON FROM PLANNED_DOWNTIME where ";
host = Convert.ToString(list[0]);
str2 = " ( SYSTEMNAME like '" + host + "'";
for (int i = 1; i < list.Count; i++)
{
host = Convert.ToString(list[i]);
str2 = str2 + " or SYSTEMNAME LIKE'" + host + "'";
}
str = str1 + str2 + " )";
string connectstring = "Data Source=SRCPA035\ovops;Initial Catalog=reporter;Persist Security Info=True;User ID=sa;Password=ril123";
DataTable dt = new DataTable();
SqlConnection connection = new SqlConnection(connectstring);
try
{
connection.Open();
SqlCommand sqlCmd = new SqlCommand(str, connection);
SqlDataAdapter sqlDa = new SqlDataAdapter(sqlCmd);
sqlDa.Fill(dt);
if (dt.Rows.Count > 0)
{
GridView1.DataSource = dt;
GridView1.DataBind();
}
GridView1.DataSource = SqlDataSource1;

View 1 RepliesBasically, I have a gridview and it has RowEditing function, which to be fair has two lines of code
GridView1.EditIndex = e.NewEditIndex;
GridView1.DataBind();
When I press the edit button from one of the row in gridview, it hides the whole gridview!
To bring it back, I have to call the function which does the binding and suprisingly, it loads back in edit mode!
I want to access the header text of bound fields programatically. suppose i have GridView1 with following bound fields:
<asp:BoundField Visible="false" DataField="ID" HeaderText="ID" /> <asp:BoundField DataField="Title" HeaderText="Title" /> <asp:BoundField Visible="false" DataField="Description" HeaderText="Description" />
how can I access their header text programmatically ( display it(either using response.write or any label)
How can i access data from text area as it is formatted.
