Hope this helps UPDATE: I've had some requests to add more data controls and to convert the code to VB etc.
So I decided to instead put the code in an assembly and make available for download here.
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 which allows the user to write some special syntax to bind against property values they would like to extract from a control.
There is alot of magic going on behind the scenes (which I will blog about in a separate post), but you do not need to know how it works to use it, e.g expression then the value of the Text property is pushed into a dictionary which the data control can retrieve later.
Forgive me for the variation in my code formatting I'm trying to find the right one.Here is a mapping of data control to method used to extract values: Grid View = public Extract Item Values As we can see with the exception of List View these oh so useful methods are protected, that means we can't call them from our code if we are using these built in controls.What can we do to surface these methods: The method itself is pretty simple.This code demonstrates how to Add/Insert, Update, delete, edit in Devexpress aspxgridview.
Sorting and changing position of columns is by default enabled. Note : You can download Devexpress controls from have tried this with versions 9.2.3 and 9.3.2.
NET 2.0 Grid View control allows us to quickly edit and delete records.
