tr>

ItemTemplate>asp:Repeater>

In code behind if I have data in
 <asp:HiddenField
Value='<%#
XPath("./NetworkCode")%>'
ID="hiddenNetworkCode"
runat="server"
/>
value I need to display the Column i.e.
 <asp:HiddenField
Value='<%#
XPath("./NetworkCode")%>'
ID="hiddenNetworkCode"
runat="server"
/>.
How can I achive this in my code behind. Below is my code behind in .aspx.cs page

protected
void
rptSearchResults_OnItemDataBound(object
sender, RepeaterItemEventArgs
e)

 {

HiddenField
hiddenEtin = e.Item.FindControl("hiddenNetworkCode")
as
HiddenField;

if
(e.Item.ItemType == ListItemType.Header
&& hdnHeader.Value.Contains("ADVN")
&&                     WorkflowState.StateData.SearchParameters.ProviderType.Value =="Facility")

 {

               TierIndicator.Visible =true;

       HtmlTableCell
thTierFacility = (HtmlTableCell)e.Item.FindControl("PFacility");

      
if (thTierFacility !=
null)
{ thTierFacility.Visible =true; 
}

 }

 if
(hiddenEtin != null)

  {

 
string strNetworkCode = hiddenEtin.Value;

 
if ((e.Item.ItemType ==
ListItemType.Item
|| e.Item.ItemType == ListItemType.AlternatingItem)                        
&& WorkflowState.StateData.SearchParameters.ProviderType.Value =="Facility") 
{

HtmlTableCell
tdTierImage = (HtmlTableCell)e.Item.FindControl("Image");

if
(!string.IsNullOrEmpty(strNetworkCode)
&& strNetworkCode.Contains("ADVN")) 
{

                      TierIndicator.Visible =true;

     
HtmlTableCell thTierFacility = (HtmlTableCell)e.Item.FindControl("PFacility");

     
if (thTierFacility !=
null) 
{    thTierFacility.Visible =true;   
}

     
if (tdTierImage !=
null) 
{ tdTierImage.Visible =true;

     
HtmlImage tImage =
new
HtmlImage();  
tImage.ID =Guid.NewGuid().ToString().Substring(0,
6);

            tImage.Alt ="";

                           tdTierImage.Controls.Add(tImage);                       }                    }

       
else   {if
(tdTierImage != null)

                      {    tdTierImage.Visible =false;

                           tImage.ID =Guid.NewGuid().ToString().Substring(0,
6);

                            tImage.Alt ="";              
tImage.Src ="";

                            tdTierImage.Controls.Add(tImage);

                        }                   }                }        

           }return;

           }

   return;           
}

 

In the above code if I have data in Item template then I need to dispaly Image in the Item and same time need to display the

Preferred
<br/>Facility?
Column Header.

Thanks,

Sureya

          

 

Ok, here you need to take a look from a little bit different angle of vision. There is model that you retrieved from database and you bind it to UI in order to display model's data in some special way. The UI may be changed as much as needed, i.e. replaced
by GridView or splitted up to several controls, hence you should not rely on it. This means you do not need to search for hidden controls (markup-specific things) in item template, rather than that use the data in your model:

protected void outerRepeater_ItemDataBound(object sender, RepeaterItemEventArgs e)
{
    if (e.Item.ItemType == ListItemType.Header)
    {
		//extract NetworkCode value from underlying model
		IXPathNavigable x = (IXPathNavigable)e.Item.DataItem;
		XPathNavigator nav = x.CreateNavigator();
		XmlElement root = (XmlElement)nav.UnderlyingObject;
		string networkCode = root.SelectSingleNode("NetworkCode").InnerText;
		//hide/display the column in header
		var isVisible = networkCode.ToUpper().Contains("ADVN");
		var column = e.Item.FindControl("PFacility") as Control;
		if (column != null)
		{
			column.Visible = isVisible;
		}
     }
}
