Image through Code Behind in a Repeater

Using the ItemDataBound event limits your flexibility in terms of controlling the rendering of the items. If you have complex logic or dynamic behavior that needs to be applied to the items, it can become challenging to manage within the event handler. 

Handling the ItemDataBound event for each item in the Repeater control can have a performance impact, especially when dealing with a large number of items. The event handler is executed for each item during data binding, which can result in slower page rendering. 

Hi ramo 

you can modify your code as follows:

1. Add an Image control to your markup code:

in your code-behind file, handle the ItemDataBound event of the Repeater control:

protected void rptData_ItemDataBound(object sender, RepeaterItemEventArgs e)
{
    if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
    {
        // Find the controls within the current item
        Literal ltrlBookTitle = (Literal)e.Item.FindControl("ltrlBookTitle");
        Image imgThumb = (Image)e.Item.FindControl("imgThumb");

        // Retrieve the data item bound to the current item
        DataRowView rowView = (DataRowView)e.Item.DataItem;

        // Set the BookTitle value to the Literal control
        ltrlBookTitle.Text = rowView["BookTitle"].ToString();

        // Set the ThumbImage value to the Image control's URL property
        imgThumb.ImageUrl = rowView["ThumbImage"].ToString();
    }
}
