I've got the following code in place to check the GridClientSelectColumn from my code behind and it indeed fires and the check boxes are checked but when the page finally renders none of the check boxes are checked. I've tried both the ItemDataBound and the ItemCreated events and neither produce a different result. The following article is were I got my code: http://www.telerik.com/community/code-library/aspnet-ajax/grid/gridclientselectcolumn-select-all-rows-with-enabled-check-boxes-only.aspx

Code behind:

protected

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

{

// get the package guid for the current iteration

if (e.Item is GridDataItem)

{

DataRowView dataRow = (DataRowView)e.Item.DataItem;

GridDataItem item = (GridDataItem)e.Item;

CheckBox checkBox = (CheckBox)item["SelectedCheckbox"].Controls[0];

checkBox.Checked = (((

int)dataRow["Selected"]) == 1);

if (checkBox.Checked)

{

string t = "";

}

}

}

protected void StepsGrid_ItemCreated(object sender, GridItemEventArgs e)

{

// get the package guid for the current iteration

if (e.Item is GridDataItem)

{

DataRowView dataRow = (DataRowView)e.Item.DataItem;

GridDataItem item = (GridDataItem)e.Item;

CheckBox checkBox = (CheckBox)item["SelectedCheckbox"].Controls[0];

checkBox.Checked = (((

int)dataRow["Selected"]) == 1);

if (checkBox.Checked)

{

string t = "";

}

}
