[Solved] hide / show grid footer on expand colapse

[Mike]

Hi I am trying to hid / show the footer when a user expands or collapses and item in the grid view, how can I achieve this 

ok so I now have this code

if (gvTakeoff.Items.Expanded == false)
           {

               gvTakeoff.MasterTableView.ShowFooter = false;

           }
           else
           {
               gvTakeoff.MasterTableView.ShowFooter = true;
           }

if (gvTakeoff.Items[0].Expanded == false)
           {

               gvTakeoff.MasterTableView.ShowFooter = false;

           }
           else
           {
               gvTakeoff.MasterTableView.ShowFooter = true;
           }

this is only checking the first item in the grid I would like it to test if any items are expanded

I would like it to check if any items are expanded if they are hide the footer, if the item is collapsed then show the footer

thanks

Hi Mike

Try the following code snippet to hide/show footer on Expand or collapse click.
C#:

protected void RadGrid1_ItemCommand(object sender, Telerik.Web.UI.GridCommandEventArgs e)
   {
       if (e.CommandName == "ExpandCollapse")
       {
           if (e.Item.Expanded)
           {
               RadGrid1.ShowFooter = false;
           }
           else
           {
               RadGrid1.ShowFooter = true;
           }
       }
   }

Thanks,
Princy.

Hi,

Please try the following code snippet to hide the footer on expanding.

C#:

protected void RadGrid1_ItemCommand(object sender, Telerik.Web.UI.GridCommandEventArgs e)
   {
       if (e.CommandName == "ExpandCollapse")
       {
           if (e.Item.Expanded)
           {
               RadGrid1.FooterStyle.CssClass = "show";

           }
           else
           {
               RadGrid1.FooterStyle.CssClass = "hide";

           }
       }
   }

CSS:

<style type="text/css">
.hide
{
    display:none !important;
}
.show
{
    display:;
}
</style>

Please ignore the previous attachment.

Hi I have tried your code but that just stopped any of my rows in the grid view from being displayed. 

This code works fine for hiding the first row which I have added to the Grid_DataBound

if (gvTakeoff.Items[0].Expanded == false)
           {

               gvTakeoff.MasterTableView.ShowFooter = false;

           }
           else
           {
               gvTakeoff.MasterTableView.ShowFooter = true;
           }

It does not hide the footer when the row is closed

Hi Mike,

Can you please try the following code snippet?

C#:

public static bool anyItemExpanded = false;
  protected void RadGrid1_ItemCommand1(object sender, GridCommandEventArgs e)
  {
      if (e.CommandName == "ExpandCollapse")
      {
         if (e.Item.Expanded)
          {
             foreach (GridDataItem item in RadGrid1.MasterTableView.Items)
              {
                  if (item.Expanded && item.ItemIndex != e.Item.ItemIndex)
                  {
                      anyItemExpanded = true;
                      break;
                  }
               }
          }
          else
          {
                anyItemExpanded = true;
          }
      }
  }
  protected void RadGrid1_PreRender(object sender, EventArgs e)
  {
      if (anyItemExpanded)
      {
          RadGrid1.MasterTableView.ShowFooter = false;
          anyItemExpanded = false;
      }
      else
      {
          RadGrid1.MasterTableView.ShowFooter = true;
          RadGrid1.MasterTableView.Rebind();
      }
  }

Thanks,
Princy.

        WDBDataContext dc = new WDBDataContext();

        long takeoffItemId = (long)e.Command.Parameters["@ID"].Value;

        takeoffSectionId = dc.TakeoffSectionItems.Where(a => a.ID == takeoffItemId).Select(a => a.TakeoffSectionID).Single();

    }

Hi Mike ,

I tested any of the suggestions Princy has provided in this thread and all of them work properly on my end. Therefore could you please open a regular support ticket and send us a sample application with the mentioned suggestions implemented which shows that they does not work on your end? Thus we will be able to revise the application locally and isolate the scenarios specifics that are causing this solutions to fail for you.

Kind regards,
