Rowupdating in gridview in asp net
To cancel the update operation, set the collections, if necessary, before the values are passed to the data source.A common way to use these collections is to HTML-encode the values supplied by the user before they are stored in the data source. In my VB Gridview, I had bind several column from datatable into one single column of the gridview. The following is the VB code: Protected Sub Grid View1_Row Editing(By Val sender As Object, By Val e As Grid View Edit Event Args) 'Set the edit index. Bind Data() End Sub Protected Sub Grid View1_Row Canceling Edit(By Val sender As Object, By Val e As Grid View Cancel Edit Event Args) 'Reset the edit index. Edit Index = -1 'Bind data to the Grid View control. But I have no idea how to get those value when doing Row Editing & Row Updating. Bind Data() End Sub Protected Sub Grid View1_Row Updating(By Val sender As Object, By Val e As Grid View Update Event Args) 'Retrieve the table from the session object. My problem lies in that the click on the Update Image Button posts back, but neither the Row Command nor Row Updating events get triggered.I have set the requisite attributes in the Grid View tag. (Note, in the gridview the Enable View State="False" - if I set it to True I get the standard "Failed to load viewstate. error) One strange thing that I've noticed that makes me think it's a View State problem is that if I change the Command Name of the Update button to "Edit" that postback event does get captured in the Row Command event...
Sql Command Dim sql3 As String Dim reader3 As System.
New Edit Index 'Bind data to the Grid View control. Bind Data() End Sub Private Sub Create Data Table() Dim cmd As New System.
Dim dt = CType(Session("dt"), Data Table) 'Update the values.
I removed everything I did with View State and edited the original post again with what I currently got. I cannot sort the Grid View because I'm trying to sort with Your code doesn't have Data Source ID.
You're accessing so many items without null checks that it could be any number of things. Are you sure all of the controls exist in the cells you're specifying?
