tooltip in grid

[Patxi]

Hello,

I need to use a tooltip for a concrete part of a grid. Concretely, I have a GridClientSelectColumn and I want to show the tooltip when a mouse is over the header. I could use HeaderToolTip but I want to apply a skin. Let´s see it with this code sniplet:

<MasterTableView...>
      <Columns>
              <telerik:GridClientSelectColumn ...>
                    <HeaderStyle Width="25px" />
              </telerik:GridClientSelectColumn>

The header is a checkbox and when is checked all the rows are selected. The tooltip must be shown when a mouse is over this checkbox. How can I make a relation if I can´t use an ID  for gridclientselectcolumn and thus aTargetControlID? do I have to do it in code behind?

Thank you in advance.

Hello Patxi,

You can add the RadToolTip to the HeaderCheckbox in the GridClientSelectColumn from code behind which seems rather simple. I implemented the same same scenario using the following code:
aspx:

 <telerik:RadToolTip ID="RadToolTip1" Text="Selects all Rows" Title="SelectAll" runat="server">
 </telerik:RadToolTip>

<telerik:RadGrid ID="RadGrid1" runat="server" DataSourceID="SqlDataSource1" OnItemDataBound="RadGrid1_ItemDataBound" >
      <MasterTableView DataSourceID="SqlDataSource1" >
       <Columns>
       <telerik:GridClientSelectColumn UniqueName="SelectColumn"></telerik:GridClientSelectColumn>
         .....
       </Columns>
     </MasterTableView>
</telerik:RadGrid>

cs:

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
    {
        if (e.Item is GridHeaderItem)
        {
            GridHeaderItem header = (GridHeaderItem)e.Item;
            ((CheckBox)header["SelectColumn"].Controls[0]).ID = "SelectCheckBox";
            RadToolTip1.TargetControlID = "SelectCheckBox";
        }
    }

Thanks
Princy.

Hi Patxi / Princy ,

Also you can try this route -

UI .aspx file:  
.
.

<

 

Columns>  

 

 

    <telerik:GridClientSelectColumn UniqueName="SelectAll" ItemStyle-Width="10px">  

 

    </telerik:GridClientSelectColumn>  

 

.
.

code behind .cs file: 

protected

 

void RadGrid_ItemCreated(object sender, GridItemEventArgs e) 

 

 

{

 

 

 

  if

 

(e.Item is GridHeaderItem) {

 

 

 

GridHeaderItem headerItem = e.Item as GridHeaderItem;
  foreach

 

(GridColumn column in RadGrid.MasterTableView.RenderColumns) {

 

  if (column.UniqueName == "SelectAll") {    

 

          (

headerItem[column.UniqueName].Controls[0] as CheckBox).ToolTip = "Select all rows";  

 

       }
   }
  }
}
Hope it helps.

Thanks,
Arif
