Get value from current Gridview column on button click

 I am searching for the answer to this, should be easy, but I just can't get it.

I have a Gridview.  I placed a button column on it.  Now each row has a button.  When they click the button I want to grab the value of one of the columns and do some stuff.  I made it a template field with a button, on in the on_click of that button I put:

myString = me.GridView1.SelectedRow.Cells("mycolumn").text

That said it was a nullRefernceException.  I know there is data in that column.  So I tried

 myString = me.GridView1.SelectedRow.Cells(1).text

Got the same thing.

What am I missing?

Thank You

You should use the RowCommand event of the GridView Control to get the cell's text.

eg. protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)




Hope this helps.

Bind the data item to the button's CommandArgument field something like this:

<asp:Button runat="server" CommandName="DoSomething" CommandArgument='<%#Eval("ID")%>' Text="DoSomething" />

Then in your RowCommand event handler you will have access to the data through the CommandArgument property like this:

protected void grid_RowCommand(object sender, GridViewCommandEventArgs e)
if (e.CommandName == "DoSomething")
// Response.Write is an example,
// but data item bound will be passed when clicked
Response.Write(e.CommandArgument); } }

How to access GridView hidden Column value by clicking a template column button?
Hi: My GridView contains(for simplicity sake) three columns: a hiden template column that contains the DocID (the DataKey), a template column that contains DocTitle and a template button column that contains a button called btnDetails. When the GridView is loaded with data, the user may click the button on a row and obtain the DocID from the hidden column of that row. This seems to be simple enough. However, when the button is clicked, the GridView always returns blank. Any idea why this happens? My code is as follows: ASPX <asp:GridView ID="gvList" runat=&...

Get Value from Hidden Column in Gridview control
I have managed to get the value from my hidden field by using the SelectedIndexChanged event and the following line of code:string keyValue = GridView1.SelectedDataKey.Value.ToString()I would however prefer to get access to the hidden column value on the GridView1_RowDataBound event, so that I can then evaluate each row against the hidden columns value and decide whether or not to display the edit button in each row. Can I do this a different way? You can use e.Row.DataItem("field name") in the RowDataBound event -  as long as the field is in your SQL statement doesn't m...
