I am using Template Field’s Item Template and Edit Item Template for providing read only and editing interface of the same column in the Grid View.
There are also two events associated with this that you can use � Row Updating and Row Updated. in the absence of batch update, both of these events are raised for each and every row being updated.
For example, if we are updating 100 rows, both of these rows are raised for 100 times.
Thanks a bunch to you and the Regards Hema '''''''''''''''''''''''''''''''''''''''''''''''''' ''''''''''''''''''''''''''''''''''''''''' reply From Brianbk [email protected] The code it update Datagridview believe me was running try this one Dim constr As String = "Data Source=localhost; Integrated Security=True" Dim sqlstr As String = "select * from Customers" Dim dt As New Data Table() Private Sub btn Load_Click(By Val sender As System. Clear() 'fill the datatable with data in the Database Dim dpt As New Sql Data Adapter(sqlstr, constr) dpt. Dispose() 'display the Table in the datagrid datagridview1. i have a problem with this code which i used it before and it really works. Now the code of Grid View rowupdating events is: Text Box txt City = (Text Box)Grid View1.(Text Box)Grid View1. Text was the updated value but the old value returns. i compared also my source code into the other which is working but there is no difference from it. Related to this problem, but much worse: I have a Grid View, which isn't bound in the ways mentioned above; I need to use a custom data source, and create the data grid cells programmatically from it. But within the Row Update event handler, everything goes null. Sorry for the wrapping in the second snippet, I just don't think there's a way to make it more eye-friendly, even if I'd raze the leading spaces. protected void Grid View1_Row Updating(object sender, Grid View Update Event Args e) please help me.
i went through for loop and if loop and did all things which were of total failure i came across this right now. The code which you provided roughly a fortnight has done wonders for me. Click 'Display the Table with data in the gridview 'clear the current content of the Table dt. Find Control("txt City"); and i assume that the txt City. Old Values and New Values both have length 0, and the Text Box approach described above gives a null reference after conversion. I've posted the ASP Code, and decided to skip the actual binding code, since it works great; checked it with the debugger.
If your data source cannot be automatically updated by Web Data Grid, you must handle the update events and update the data manually.
