Hello Balaji,

Use the same logic as desribed in documentation for craeting the GridTemplateColumn. Now access the control in ItemDataBound event and set the DataSource from code behind.

Sample code:

protected void RadGrid1_ItemDataBound(object sender, Telerik.Web.UI.GridItemEventArgs e)

{

if (e.Item is GridEditFormItem && !e.Item.IsInEditMode)

{

GridEditFormItem editItem = (GridEditFormItem)e.Item;

RadComboBox combo = (RadComboBox)editItem.FindControl("controlID");

combo.DataSource = dt; // set the datasource here

}

Thanks,
Princy.

hi princy

thanx again for your reply. i've gone through the document

this is how i made template column for edit and item. I 'm not able to make this work in edit mode.

GridTemplateColumn templateColumn = new GridTemplateColumn();

templateColumn.EditItemTemplate = new MyEditTemplate(templateColumnName);

templateColumn.ItemTemplate = new MyTemplate(templateColumnName);

templateColumn.HeaderText = _i2Object._i2Arguments[i].DisplayName;

templateColumn.DataField = _i2Object._i2Arguments[i].DataTextField;

this.RadGrid1.MasterTableView.Columns.Add(templateColumn);

public class MyTemplate : ITemplate

{

protected RequiredFieldValidator validatorTextBox;

protected TextBox textBox;

private string colname;

public MyTemplate(string cName)

{

colname = cName;

}

public void InstantiateIn(System.Web.UI.Control container)

{

textBox = new TextBox();

textBox.ID = "templateColumnTextBox";

textBox.DataBinding += new EventHandler(textBox_DataBinding);

validatorTextBox = new RequiredFieldValidator();

validatorTextBox.ControlToValidate = "templateColumnTextBox";

validatorTextBox.ErrorMessage = "*";

container.Controls.Add(textBox);

container.Controls.Add(validatorTextBox);

}

public void textBox_DataBinding(object sender, EventArgs e)

{

TextBox txt = (TextBox)sender;

GridDataItem container = (GridDataItem)txt.NamingContainer;

txt.Text = ((DataRowView)container.DataItem)[colname].ToString();

}

Hi Eyup,

Thanks for your replay .

I am using GridClientSelectColumn to select row of rad grid . using the this column i am able to select single row and multiple row and these rows are persistence during the various operation or rad grid such as paging ,sorting and grouping .
i have one button on page that gets all selected rows of radgrid ,but i am not able to get all these row .
to get all selected rows, i am using following code

_grdDataListView.MasterTableView.AllowPaging = false;
                _grdDataListView.Rebind();
                int aas = _grdDataListView.Items.Count;
                foreach (GridDataItem item in _grdDataListView.MasterTableView.Items)
                {

                    CheckBox _chkBox = (CheckBox)item["ClientSelectColumn"].Controls[0];
                    if (_chkBox.Checked == true)
                    {
                        _temp.Add(Convert.ToInt32(item.GetDataKeyValue(this.DataKeyNames[0].ToString())));
                    }
                    //String str = item["ColumnUniqueName"].Text;

                }
                _grdDataListView.MasterTableView.AllowPaging = true;
                _grdDataListView.Rebind();

Hi Jack,

The forum thread (Creating EditItemTemplate of GridTemplateColumn programmatically) you are looking for is not active anymore since it was for RadControls for ASP.NET which was discontinued in 2009 in favor of RadControls for ASP.NET AJAX - now called Telerik UI for ASP.NET AJAX.

For your convenience, I pasted the forum thread discussion in a Word file and attached it to my reply.
