Tooltip in datagrid

lily611 · August 30th, 2004, 12:55 AM

Hi,

I would like to set tool tips for the data grid column. The
functionality should allow an help tooltips to be displayed whenever
the user moves mouse over each column.

every webcontrol has a string property that called ToolTip,
you can set this property for every DataGridItem object ...
or you can bind it(i.e to a column in your datasource) in ItemTemplate
HtH.

I can the property with datagrid but how to set with a particular column of the datagrid, please write in detail.

you cant assign a ToolTip to a column of the grid,you should work only with DataGridItem objects,
work with DataGridItems of a specific column and assign them a joint value ...

something like below

Code:

private void BindGrid()
{
   //...
   DataGrid1.DataSource=ds//a simple DataSet
   DataGrid1.DataBind();
   //...
   foreach(DataGridItem dgItem in DataGrid1.Items)
   {
           dgItem.Cells[0].ToolTip="Column0";
           dgItem.Cells[1].ToolTip="Column1";
           dgItem.Cells[2].ToolTip="Column2";
           //....other cells like above
   }
}

The appropriate place to put this code is in the ItemDatabound event of the grid. It will fire for each row of the grid. You dont need to iterate through the items in the grid.

private void DataGrid1_ItemDataBound(object sender, System.Web.UI.WebControls.DataGridItemEventArgs e)
{
     e.Item.Cells[0].ToolTip = "Column0";
     e.Item.Cells[1].ToolTip = "Column1";
     e.Item.Cells[2].ToolTip = "Column2";
     //....other cells like above
}

Hello Ganesh,
yes great place ,but consider a grid including rows arent going to be bound ....
just in that situation we have to iterate through the items in the grid,

You are right Mehdi.. Can you give me an example in which a datagrid is used without databinding.

I didnt mean a DataGrid object,I dont think a DataGrid(or DataList or Repeater) could work correctly without databinding!!!?...
I meant something like Table objects without any databinding
