Find Specific Hierarchical Grid When Clicking Button in CommandItemTemplate

[john81]

I have a Hierarchical Grid with a CommandItemTemplate defined in the GridTableView so that each child table has the same Button control that when clicked will reset its filter columns.  What I can't figure out is how to get a reference to the parent GridTableView of the button in the server side button click.

I know how to traverse the ALL the child GridTableViews but I just want to reset the column filters on the GridTableView that the button was clicked in.  To do that I need a reference to the parent GridTableView of the button.  Any ideas how I can get a reference to that?

Hi,

I guess you want to access the parent table from the detail table on the CommandItemTemplate button click. Please try the following code snippet.

C#:

protected void RadGrid1_ItemCommand(object sender, GridCommandEventArgs e)
{
  if (e.CommandName == "ClearFilters" && e.Item.OwnerTableView.Name == "GridTableViewName")
   {
     GridDataItem parentItem = (GridDataItem)(e.Item.OwnerTableView.ParentItem);//Accessing the parent row
     string value = parentItem.GetDataKeyValue("ID").ToString(); //Access parent datakey value
     //Your code
   }
}

Thanks,

Not quite what I'm looking for.

If I have say 20 parent records and 20 child GridTableViews, I will have 20 Clear Filter buttions, one for each child GridTableView.

I need to get a reference to the specific GridTableView so I can clear the filters on it using this code below.  I don't want to clear the filters on all the GridTableViews, just the one where the Clear Filter button was clicked.  So the object "gridTableView" in the code below needs to be a reference to the GridTableViews where the button click occurred.

foreach (GridColumn column in gridTableView.Columns)
{
    column.CurrentFilterFunction = GridKnownFunction.NoFilter;
    column.CurrentFilterValue = string.Empty;
}
gridTableView.FilterExpression = string.Empty;
gridTableView.Rebind();

Hi,

You can try the following code snippet to clear the current DetailTable filter.

C#:

if (e.CommandName == "ClearFilters" && e.Item.OwnerTableView.Name == "GridTableViewName")
{
  foreach (GridColumn col in e.Item.OwnerTableView.Columns)
  {
      col.CurrentFilterFunction = GridKnownFunction.NoFilter;
      col.CurrentFilterValue = String.Empty;
  }
  e.Item.OwnerTableView.FilterExpression = String.Empty;
  e.Item.OwnerTableView.Rebind();
}
