No alt text for binary image column

[miksh]

If a field used to display the image alt text is NOT type of string (e.g. int) then the alt text is not generated
E.g.

<telerik:GridBinaryImageColumn
        DataField="MyImage"
        DataAlternateTextField="MyId" DataType="System.Int32"
        DataAlternateTextFormatString="{0}"
        ImageAlign="Middle"
        HeaderText="Image" FooterText="Image"
        HeaderStyle-Width="50"
        AllowFiltering="false" AllowSorting="false"
        Groupable="False"  ResizeMode="Fit" ImageHeight="50px" ImageWidth="50px"
        ReadOnly="True" DefaultImageUrl="../img/noimage.png">
</telerik:GridBinaryImageColumn>

Hi,

Please take a look into the following code snippet I tried to give Alternate text as integer for GridBinaryImageColumn.

C#:

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
{
    if (e.Item is GridDataItem)
    {
        GridDataItem ditem = (GridDataItem)e.Item;
        RadBinaryImage image = (RadBinaryImage)ditem["MyImage"].Controls[0];
        if (image.DataValue == null)
        {
            image.AlternateText = DataBinder.Eval(ditem.DataItem, "MyId").ToString();
        }
    }
}

Thanks,
Shinu.

Thanks Shinu but my point was that it sounds like a bug in RadGrid.

Hi Michael,

Indeed I verified that the described issue exists into the current version of our controls. However our developers are aware and they will start working on the resolution of this issue.
