Is there a way to find out which column is selected in the Gridview row command? When I click on a gridview row in a specific column, is there a way to get the column index of the selected row?

View 1 RepliesI have a column in SQL Server 2008 called MapLocation which is stored as the geography data type. This column is used to store the location of a building in one table, and the location of landmarks in another table. I have to list all landmarks within 4 miles of a building.
I have a clustered primary key on an automatically generated int column in each table. I assume that I need to create a spatial index on the MapLocation column in the landmarks table. This I guess would aid finding all landmarks within 4 miles.
My problem is that I am not sure what settings to use for this spatial index. I have set the spatial index to have the following settings:
Cells per object: 16 Level 1: Medium Level 2: Medium Level 3: Medium Level 4: Medium Tessalation Scheme: Geography gridAre these the best settings? Am I doing the right thing?
I have a gridview with the following information

index = Convert.toInt32( GridView1.FindControl("Name").toString())
but that isnt working. Kindly note, I do not want to hardcord the position as 0, instead I would like to find it

View 3 RepliesI have a listview control which is bound to DataTable object. When a user clicks "Add", I am creating a new row in the underlying datasource and refreshing the datatable so that it includes the new row and displaying the listview. My requirement is to "select" the newly added row after listview is refreshed. I have the ID of the newly created row and it is bound as one of the columns in the datatable.Now my question is, how can I get the index of that particular row which was newly created from the Listview so that I can set its SelectedIndex.

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

View 9 RepliesHow to add a button at first column of gridview and get cell value in another column?
For example, add a button named it as "Click me". Once user clicks will get third column cell's (ID) value.
I have a gridview and the OnRowDataBound event is linked to this function:
if (e.Row.RowType == DataControlRowType.DataRow)
{
ThisRow = e.Row.DataItem as MyObjectModel;
if (ThisRow.Property1 == null) { e.Row.Cells[5].Text = "-"; }
This code looks at the value of a property of the object in the data source and if it's null, converts the null to display "-" in column 5. The problem I'm having is that if I change the order of the columns of the gridview, then I need to change the index of every other modification. What I'd like to do is change the statement "e.Row.Cells[5].Text" to something that says "the cell whose column header is xyz".

I am trying to write a small method to loop through and find a GridView Column by its Index, since it can change position based on what might be visible.

{
if (col.ColumnName.ToLower().Trim() == name.ToLower().Trim()) return col.Ordinal;
