 I'm trying to add a tooltip for my custom column of the fileexplorer - here is the code:

void Grid_ItemDataBound(object sender, GridItemEventArgs e)         
{
    foreach (GridColumn column in RadFileExplorer1.Grid.MasterTableView.RenderColumns)                 
    {                     
        if ((column is GridTemplateColumn) && (column.HeaderText.Equals("Document Title")))                     
        {                         
            if (e.Item is GridDataItem)                         
            {                             
                GridDataItem gridItem = e.Item as GridDataItem;                             
                string text = gridItem[column.UniqueName].Text;  
                
                //this line will show a tooltip
                            
                gridItem[column.UniqueName].ToolTip = text;                         
            }                                              
        }                 
    }             
}


I'm unable to get the value of the cell - can you please help?

Hi Neepa,

I guess you want to show tooltip for a GridTemplateColumn.Please try the below sample code snippet.In the code snippet I have shown how to access a bound column,as well as a template column,and set the tooltip accordingly. In order to set the tool tip for a column for its datakey value,you can use
gridItem[column.UniqueName].ToolTip = "Column Name:" + gridItem.OwnerTableView.DataKeyValues[gridItem.ItemIndex]["UniqueName"].ToString();

ASPX:
<telerik:RadGrid ID="RadGrid1" runat="server"  onitemdatabound="RadGrid1_ItemDataBound">
    <MasterTableView DataKeyNames="OrderID">
        <Columns>
            <telerik:GridBoundColumn UniqueName="OrderID" DataField="OrderID" HeaderText="OrderID" />                  
                <telerik:GridTemplateColumn HeaderText="TemplateColumn" UniqueName="TemplateColumn">
        <ItemTemplate>
            <asp:Label ID="Label1" runat="server" Text=' <%# Eval("ShipCity") %>'></asp:Label>
        </ItemTemplate>             
    </telerik:GridTemplateColumn>
        </Columns>
    </MasterTableView>
</telerik:RadGrid>

C#:
protected void RadGrid1_ItemDataBound(object sender, Telerik.Web.UI.GridItemEventArgs e)
{
    foreach (GridColumn column in RadGrid1.MasterTableView.RenderColumns)
    {
        if (column is GridTemplateColumn)
        {
            if (e.Item is GridDataItem)
            {
                GridDataItem gridItem = e.Item as GridDataItem;
                string itemValue = gridItem["OrderID"].Text; //Access boundcolumn value
                Label labeltext = (Label)gridItem.FindControl("Label1");//Access template label value                  
                string text = labeltext.Text;
                gridItem[column.UniqueName].ToolTip = "OrderID: " +itemValue  //Gives the tool tip value of bound column
              // gridItem[column.UniqueName].ToolTip = "ShipCity: " +text;//Give the tooltip value of the template column
 
            }
        }
    }  
}

Hope this helps,
Let me know if any concern.

Thanks,
Princy

Princy,

It is actually the tooltip for my file explorer's custom column.  I'm able to get the tooltip to work but the value it is grabbing is not correct - I want to grab the value that is in the cell.

Hi Neepa,

To get the value of the cell for a template column,please try the following code snippet.If this doesn't help,can you please provide your full code.

ASPX:
<telerik:GridTemplateColumn HeaderText="TemplateColumn" UniqueName="TemplateColumn">
  <ItemTemplate>
    <asp:Label ID="Label1" runat="server" Text=' <%# Eval("ShipCity") %>'></asp:Label>
  </ItemTemplate>
</telerik:GridTemplateColumn>

C#:
protected void RadGrid1_ItemDataBound(object sender, Telerik.Web.UI.GridItemEventArgs e)
{
    foreach (GridColumn column in RadGrid1.MasterTableView.RenderColumns)
    {
        if ((column is GridTemplateColumn) && (column.HeaderText == "TemplateColumn"))
        {
            if (e.Item is GridDataItem)
            {
                GridDataItem gridItem = e.Item as GridDataItem;          
                Label labeltext = (Label)gridItem.FindControl("Label1");//Access template value                  
                string text = labeltext.Text;          
                gridItem[column.UniqueName].ToolTip = "ShipCity: " +text;
            }
        }
    }  
}

    RadFileExplorer1.Grid.ItemDataBound += new GridItemEventHandler(Grid_ItemDataBound);
}

void Grid_ItemDataBound(object sender, GridItemEventArgs e)
