Binding a datagrid

[syno]

Hi Guys

I have an editable datagrid with Edit, Update and Cancel controls shown as links within my datagrid. However when I click on the Edit, Update and Cancel links within my rendered table the table disappears. I know these link controls work because I have a push button that gets a dataset to bind to the datagrid and then databinds the datagrid to the data source. If I click on the push button (which effectively does a free text search) the table does appear. However when I press the Edit, Update and Cancel links the table disappears. The code I am using for the Edit option is as follows. Is there anything else I should be doing to bind the datagrid on selecting Edit:


Public Sub DataGrid_Edit(ByVal Source As Object, ByVal E As DataGridCommandEventArgs)
dgSearch.EditItemIndex = E.Item.ItemIndex
DataBind()
End Sub

Thank you

What does [tt]databind()[/tt] do? I guessing it gets your data and binds to the grid. You refer to your grid as a DataGrid not GridView... I assume your using .Net 1.1 and not 2.0. Is this correct?

Is viewstate enabled for the grid? If so, you should not need to bind the grid when changing the edit item index. Just change the EditItemIndex like you do and your done. Don't call [tt]DataBind()[/tt]

if you don't have viewstate enabled call [tt]DataBind()[/tt] first and then change the EditItemIndex.

Public Sub DataGrid_Edit(ByVal Source As Object, ByVal E As DataGridCommandEventArgs)
        DataBind()
        dgSearch.EditItemIndex = E.Item.ItemIndex
End Sub

If this still doesn't work there may be a problem within the method [tt]DataBind[/tt].

Are you databinding the DataGrid in your Page_Load method.

If so, is it wrapped in a PostBack block

Thanks Guys

That did it. The BindData method was not loaded incorrectly. I now have a BindData method that calls a post back block.

I used the following tutorial at:

Your advise was invaluable!
