Setting Datagrid Column to invisible when Column is an AutoGeneratedColumn NOT a bound Column
Just like the title says, I'm trying to set a column to invisible but I'm unable to do so.
If I bound the column I can used the code:
me.datagrid.Column.Item(1).Visible = False
But since I'm wanting the column NOT to be bound (there are a number of sql scripts that populate the same datagrid so I cannot bound all the columns since the columns are different for each script etc etc etc) how do I set an AutoGeneratedColumn to invisible??
I have a datagrid with a bound column and a template column as given below.When I scan through the grid, I get the value of the first column (bound column). However, I cannot get the value of the second column (Template Column). I can see the data in both columns though.////////////////////////////////////////////////////////////////////////////////////<AlternatingItemStyle BackColor="#e0e0e0"></AlternatingItemStyle><Columns><asp:BoundColumn DataField="Facility" HeaderText="Facility"> </asp:BoundColumn><asp:TemplateColumn HeaderText="Facility2"><ItemSty...datagrid columns bound to columns from different tables
I have a dataset with multiple tables. Is there a way to bind each of the datagrid's columns to a column from a different tables?
Thanks in advance!
The bottom line, yes you can, but it would take some custom methods getting called from a template column and some other fancy tricks.
But, the datagrid is designed and works best when it's given it's one datasource. If you need data from different columns in different tables, I would make a custom datatable that reflects the columns you need and use that custom datatable has the datagrid's datasource.

I'm nuts - what I've used before isn't working. Have a datagrid with add, edit, update, delete functions. Everything works except the update function - getting blank when trying to retrieve the indexItem key. (set keyfield in datagrid, also have first column as bound column) On the edit button click, I can write the bound column value to a label and then reference that, but surely there's a clearn er way? Any help?

I create few template column and bound column in datagrid. One of the template column contain the StudentMark. I want to know how to change that column to (Read only) or "Not" (Read only) when click the edit button. It is based on a dropdownlist to determine to read only or not.

I have a dataset being filled by an adapter and stored procedure.
My datagrid is bound to the dataset.
If a blank field is returned from the database, I do not want the relevant bound column in the datagrid to be displayed.
Does anyone know how to do this....?? Thanksss
You can hide the column or cell in the ItemDataBound event.
Do you mean that if none of the rows contain a value for a particular column, then you want to hide the column? If so then your best option would be to remove the column from datasource before performing the databinding.

hopefully a quickie :-)
I have a datagrid with a bound column displaying a value returned from a database. I wanted to sort the value in the grid numeric ascending when the column is clicked, so I added a sort procedure and this works fine.
Next, I decided to replace the text header to be an image. So I added a headerimageurl:
<asp:datagrid id="grid1" onsortcommand="grdSort" onItemCommand="grdItem" ... >
<asp:boundcoumn ... headerimageurl="\image.jpg" sortexpression="counter">
