Showing rows expanded in heirarchical grid

[Manoj]

Hi,

I am using a heirarchical grid which is nested till level 3 and want to show some rows in the inner detail grids to be expanded. I wish to do this programmatically if the rows match some criteria.

I tried the following but it does not seem to work-

protected void Page_PreRender(object sender, EventArgs e)
{
    foreach (GridDataItem masterItem in RadGrid1.MasterTableView.Items)
    {
        // loop through the element under each category
        foreach (GridDataItem detailitem1 in masterItem.ChildItem.NestedTableViews[0].Items)
        {
            foreach (GridDataItem detailitem2 in detailitem1.ChildItem.NestedTableViews[0].Items)
            {
                if (...my criteria..)
                {
                    detailitem1.Expanded = true;
                    //also tried the one below
                    //RadGrid1.SelectedIndexes.Add(masterItem.ItemIndex, detailitem1.ItemIndex, detailitem2.ItemIndex);
                }
            }
        }
    }
}

Can someone please help...

Thanks,

Hi Manoj,

I guess you want to expand the innermost table based on some condition in second details table. I can see that you looped through the inner detail table and tried to expand the second. Here I tried to loop through the element of second table and expanded inner table based on the criteria.

CS:

protected void RadGrid1_PreRender(object sender, EventArgs e)
{
    foreach (GridDataItem masterItem in RadGrid1.MasterTableView.Items)
    {
        if (masterItem.Expanded)
        {
            // loop through the element under each category
            foreach (GridDataItem detailitem1 in masterItem.ChildItem.NestedTableViews[0].Items)
            {
                if (detailitem1["OrderID"].Text == "10643") // check the criteria
                     detailitem1.Expanded= true;
            }
        }
    }
}

Thanks,
Princy.
