Its very nice to get the auto generated column number in grid it will work like the serial number for grid with respect to the auto generated number in grid call the server side method in c# file and binding images into the grid.
HTML Code
<tr>
<td style="height: 5px" width="10%" align="center">
<img src='<%# GetText(Container.DataItemIndex + 1) %>' alt='<%# Container.DataItemIndex + 1 %>' /> </td><td style="width: 3px"></td>
Container.DataItemIndex + 1 its generated the unique value.
C# Code
GetText(Container.DataItemIndex + 1) GetText is calling the server side method.
server side Code
The method defined in server side it should be public and returning the string value.
public string GetText(int PropertyId)
{
return @"Images/Number/" + PropertyId + ".jpg";
}
by this method code is returning the image link already present in application.
