Hiding the 'Add New' button in DetailTables

[Martin]

Depending on a value in the expanded parent row, I want to display/hide the 'Add New' button in the DetailTable.  For instance, if 'Test A' in the MasterTableView is inactive, I don't want the 'Add New' button to appear if 'Test A' is expanded to show the DetailTable.  Any help would be appreciated.

Hi Martin,

You could hide the Add New Record button for a specific DetailTable by calling the code below:

this.RadGrid1.MasterTableView.DetailTables[detailTableIndex].CommandItemSettings.ShowAddNewRecordButton = false

Additionally, to check if a item in the RadGrid is expended you you could take a look at the code below:

foreach (GridDataItem item in this.RadGrid1.Items)
{
    if (item.Expanded)
    {
        //your code logic here
    }
}

I have created a little code demo to show a possible scenario that should be close to what you are requesting.

protected void RadGrid1_ItemCommand(object sender, GridCommandEventArgs e)
{
    if (e.CommandName == RadGrid.ExpandCollapseCommandName)
    {
        if (e.Item.Expanded)
        {
            e.Item.OwnerTableView.CommandItemSettings.ShowAddNewRecordButton = false;
        }
    }

}

All the best,
