Siva/Vince,

I am trying to add a templated link button to the second column of the bound webgrid at run time, but it always getting added to the first column. I have the following code.

DataTable

tblShipment = new DataTable("Shipment");

tblShipment.Columns.Add(

new DataColumn("Day", typeof(string)));

//Add templated cloumn

"Templated";

tc.Header.Caption =

"Date";

tc.CellTemplate =

new PlaceHolderTemplate();

new DataColumn("Total Cartons", typeof(string)));

tblShipment.Columns.Add(

new DataColumn("Total Weight", typeof(string)));

private

class PlaceHolderTemplate : ITemplate

ITemplate Members

public void InstantiateIn(Control container)

{

CellItem ci = (CellItem)container;

if (ci.Cell.Column.Key == "Templated")

{

LinkButton lnk = new LinkButton();

lnk.ID =

"LinkButton1";

"onClick", "ClientClick();");

ci.Controls.Add(lnk);

}

}

}

protected

void wbgData_InitializeRow(object sender, RowEventArgs e)

{

"test";

}

How do I assign a value from datareader to templated link button.

Appreciate your help.

Thanks.

Hi Vince,

I changed my code based on your suggestion.

Now it is working fine.

Tnak you very much for your support

Siva,

A row's Index property reflects its position in the Rows collection that contains it.  Each data island (a set of rows with the same parent row) has its own Rows collection.  Because of this, the first row in each data island has an index of 0.  So, given what code you've written, the result is correct.

Instead, I recommend that you use the row's BandIndex property instead.  This property reflects the row's position with respect to all other rows in the same band, regardless of which parent row to which they belong.  So, your code to get your "item" variable would be updated to:

CellItem item = ((CellItem)((TemplatedColumn)e.Row.Cells[4].Column).CellItems[e.Row.BandIndex]);

Hi,

The problem is when getting CellItem I made a mistake in InitializeRowEvent

CellItem

item = ((CellItem)((TemplatedColumn)e.Row.Cells[4].Column).CellItems[e.Row.Index]);

LinkButton  lnk = item.FindControl("lnk") as LinkButton ;

For example grid is binded like this

First Band

        SecondBand

                 Third Band

                        Fourth Band  --- In this band i had Templated column and i need to attach Javascript function for the link button which is in this templated column.

In order to get cellitem i am using above logic

Javascript function is attaching but the problem is grid is binding like this.

Parent1

       Child11

             Child111

                    Child1111   --- RowIndex - 0

                    Child1112   --- RowIndex - 1

                    Child1113   --- RowIndex - 2

Parent2

      Child22

           Child222

                  Child2221   --- Again Row Index is initializing to 0, so same cellitem it is referrencing

                  Child2222

                 Child2223              

Please correct me where i made mistake?
