Forms Data Controls :: Way To Select Item In A ListView - How To Get Appropriate Index Number

Sep 7, 2010

I've implemented a ListView to display selected data from a DataTable. My listview is one row high and 4 columns wide. I've setup a DataPager to the left of it and another to the right to allow the user to access any item in the ListView.My problem is simple: When the user adds a new item to the DataTable, I rebind the data again { e.g. listView1.DataBind() }, and then I proceed to select that newly added item. BUT no matter what I try, nothing works! More precisely, I do this: listView1.SelectedIndex = #; where "#" is the appropriate index number.

Forms Data Controls :: Refer To Cells By Column Name Rather Than Index?

Jan 4, 2010

When I use code from this thread: [URL] (converted to VB.net), the result for lblStatus is always "nothing"?

It's not clear for me why you use "label", because the fieldtype I am searching for in the gridview, is boundfield.

Data Controls :: How To Make A Column Invisible In GridView Control

Jan 25, 2013

I bound the gridview having some fields(ID, StudName, City)  and Display Button. When I click on the Disply button I approve the student and updation will happen. 

Bu what happen the column ID is not in the sequence. Sometime it displays 1,2,3,4,5,6 ...  next time it will display 7,8,9,10,11.... I want a sequence for the column ID. For that I used : 

<%# Container.DataItemIndex+1 %>

and it is working fine.. But again I realize that these numbers are generating at runtime and i can't refer to that student. Also I don't want to display ID column on the grid view but I want to use on runtime generated column. [ i am using RowCommand for ID column ] How it is possible?
