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.
NET 2.0 databound control) with Data Source control, it won't automatically query and fill the parameters collection of the updating/deleting/... In such cases, we need to manually extract the field values from the Template control. In that case you can do it using the Extract Values From Cell method to make the New Values collection yourself.
EDIT: I found a piece of code in the comments of this blog: I'm not sure for I haven't tried but the statement says you need to use the Data Source ID property in binding with the Grid View.
To cancel the update operation, set the collections, if necessary, before the values are passed to the data source.
It's an event designed to give you an opportunity to validate the input and prevent the changes going forward if need be.
thank you :) event is fired the changes have not yet been committed back to the datasource.
Notice that the programing is not running the event Row Updated any help?
Close() End If End Sub the problem is that the event row Updating is returning the old values so how can i get the new values for the update?
You can not attach validation controls directly to these Text Boxes.
