C# syntax to get value from Grid row

I have a Rad Grid with a Hyperlinkcolumn that I would like to have a conditional image displayed based on the value of another field. I am getting all kinds of errors and was hoping for some guidance.

My ASPX page is

                <telerik:GridHyperLinkColumn AllowFiltering="False" AllowSorting="False" DataNavigateUrlFields="AUTOID" DataNavigateUrlFormatString="MCDPermitView.aspx?ID={0}" DataTextField="AUTOID" EditFormHeaderTextFormat="test {0}:" FilterControlAltText="Filter AUTOIDCOLUMN column" HeaderText=" " ImageUrl="/images/Info-Small.png" UniqueName="AUTOIDCOLUMN">

                    <HeaderStyle Width="30px" />

                </telerik:GridHyperLinkColumn>





                <telerik:GridBoundColumn DataField="GIS" Display="False" FilterControlAltText="Filter GIS column" HeaderText="GIS" ReadOnly="True" UniqueName="GIS" Visible="False">
                </telerik:GridBoundColumn>

My Code behind

 protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
        {
            if (e.Item is GridDataItem)
            {
                GridDataItem dataItem = e.Item as GridDataItem;

             

                if (dataItem["GIS"].Text == "yes")
                {
                     (dataItem["AUTOIDCOLUMN"].Controls[0] as Image).ImageUrl = "/images/YES.png";

                }
                else
                {
                     (dataItem["AUTOIDCOLUMN"].Controls[0] as Image).ImageUrl = "/images/NO.png";
                }
            }
        }

if (e.Item.ItemType == GridItemType.Item || e.Item.ItemType == GridItemType.AlternatingItem || e.Item.ItemType == GridItemType.SelectedItem)   
            {   
                GridDataItem item = (GridDataItem)e.Item;   
                Image img = (Image)dataItem["AUTOIDCOLUMN"].Controls[0];     
                if (item ["GIS"].Text == "yes")
                {     
                   img.ImageUrl =  "/images/YES.png";
                }

Thanks for the help and code.. A copy/paste of your code I am getting a syntax error on the "if" line that dataItem does not exist in the current context

After all day I have figured out a working solution. there was more to the error, which by the way                 GridDataItem item = (GridDataItem)e.Item;  
need to be changed to                 GridDataItem dataitem = (GridDataItem)e.Item;   hence the first error.  The 2nd problem I found was the Column type. Since it is a Hyperlink type this changed the way the code had to be written too.  

Hope this helps anyone else



 if (e.Item is GridDataItem)
            {
                GridDataItem dataitem = (GridDataItem)e.Item;
                TableCell cell = (TableCell)dataitem["GIS"];
                
                HyperLink hyplnk = (HyperLink)dataitem["AUTOIDCOLUMN"].Controls[0];

              
                if (cell.Text == "yes")
                {
                    hyplnk.ImageUrl = "/images/Info-Small.png";
                }

                else
                {
                    hyplnk.ImageUrl = "/images/NO.png";
                   //  Or hide all together...    hyplnk.Visible = Convert.ToBoolean("False");
                }

            }
