Hi Myriam,

Try the following work arround.

CS:

protected void RadGrid2_PreRender(object sender, EventArgs e)
    {
        foreach (GridDataItem dataItem in RadGrid2.Items)
        {
            foreach (GridColumn col in RadGrid2.Columns)
            {
                if (dataItem[col.UniqueName].Text == string.Empty)
                    dataItem[col.UniqueName].Text += " ";

            }
        }
    }

Thanks
Shinu.

Hello Myriam,

I suggest you another approach:

<telerik:GridBoundColumn
DataField="CategoryID"
DataType="System.Int32"
EmptyDataText="&amp;nbsp;"
HeaderText ...

Hello
I'm REALLY REALLY sorry, but I just saw that my problem is only with templatecolumns....
And it doesn't have a EmptyDataText property....

Does it have another property who does the same thing for a templatecolumn...

Thanks in advance

and sorry for that mistake, my fault

Hello Myriam,

Just add   tag in your ItemTemplate/EditItemTemplate.

<ItemTemplate>
&nbsp;<asp:TextBox ID="TextBox1" ... />
</ItemTemplate>

Dear Daniel,

I have try EmptyDataText function.
However, it only works when data is null.
The datatype is empty string ( String.Empty ), it won't work.
so, is it possible to support when data equal to empty string, emptydatatext function will work ?

thank you

In other words, when the data type is string and data is null or empty, it shows " "

Hello Jason,

You could add the non-breaking space tags manually on ItemDataBound as shown below:

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
{
    if (e.Item is GridDataItem)
    {
        foreach (TableCell cell in e.Item.Cells)
        {
            if (String.IsNullOrEmpty(cell.Text.Trim())) cell.Text = " ";
        }
    }
}

Dear Daniel,

Yes, I know it.
If the function would built in RadGrid, that will be great.
