Grouping - Count Checked Items?

[Daniel]

I simply cannot figure out how to do this, and feel like I'm probably missing something pretty basic, but I can't figure it out or find anything in the help/forums.

I've got my grid. Each row has a checkbox.

In my header, i'm counting the total records, but I'd also like the count the total that are checked.

HELP!!

That helps, but I need to be able to display this in a group header. (and I've got multiple levels of grouping).

Hi Daniel,

Try the following code snippet in order to show the number of the checked rows in the GroupHeader.

CS:

protected void Button1_Click(object sender, EventArgs e)
{
    foreach (GridGroupHeaderItem groupHeader in RadGrid1.MasterTableView.GetItems(GridItemType.GroupHeader))
    {
        int count = 0;
        GridItem[] children = groupHeader.GetChildItems();
        foreach (GridItem child in children)
        {
            GridDataItem dataItem = child as GridDataItem;
            if ((child.FindControl("checkbox") as CheckBox).Checked)
                count++;
        }
        groupHeader.DataCell.Text = count.ToString();
    }
}

Thanks,
Shinu.

Your code worked, but I had a moment of ingenuity and figured how to do it without any code:

I added a field to my SQL that took my bit and cast it to a tinyint:

cast(Abstracted as tinyint) as AbsNum

From there, I was able to add a column and do a true sum on it.

Just wanted to post for others, if you can't see the forest for the trees like myself!
