Value in rowupdating
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.
My guess is that I am not using the correct VB to retrieve the value from the dropdown list.I just want to set a database field to a value, in code, in a grid event, the field is hidden in de editform. I think we are talking in circles, so i'm changing tactics.. By his account the system knows he is from the company "PROOVIT".bacause the user is not allowed to set it, the application must provide it, a client id for i.e. So, orders inserted by him must, whem saved, also save the client ID.The suggestion shinu made, does not provide a aolution because i can't SET the new value, i can only RETRIEVE it.Binding (Bind("") ) is no solution, because it is NOT a fill-in field, its a auto updated field. Then you can handle the Update Command event of the grid and do the same as in the Row Updating event handler of the Grid View. Sincerely yours, Iana the Telerik team I spend hours trying different ways, but still no solution...I have my code working so that the current value shows in the first of the two True/False columns (trying one as a test).
When I go to edit the column, the drop down list appears correctly.
Row Index; so i contain rowindex now u can update appropriate row according to u r Stored Procedure I know how to update with HTML, But I want in C# How To Update protected void Price Ep_Row Updating(object sender, Grid View Update Event Args e) How to Update with The Help Of Csharp. Regards atul singh Thank you very much Sri Lakshmi Infact i had posted a query regarding the same a few backs ago.
Hi, I've been working with the grid now for a week, nice features! I changed the edit template, but had some problems with the radcombo, because of faulty data. Hi Proovit, The selected value of the combobox would be available in the extracted values collection in case you bind it with the two-way binding method, e.g. Otherwise you can try the suggestion that Shinu provided. Regards, Iana the Telerik team Thanks Iana for your reply, It seems a simple question...
