ASP.NET GridView - Format Template column data using format strings and Custom Methods

This article contains GridView template column formatting through Data Format String, ternary operator blocks and custom methods.

Using Format String
Date time


<itemtemplate>
<asp:Label ID="lblDOB" runat="server" Text='<%# Eval("DOB","{0:d}") %>'></asp:Label>
</itemtemplate>
</asp:TemplateField>

For Long Date,

<itemtemplate>
<asp:Label ID="Label8" runat="server" Text='<%# Eval("DOB","{0:d}") %>'></asp:Label>
</itemtemplate>
</asp:TemplateField>

Using ternary operator

<ItemTemplate>
<asp:Image
ID="ImageOpenPending" runat="server"
ImageUrl='<%# Convert.ToInt32(Eval("StateId")) == 1 ? "~/images/icons/DashBoard_Green_Bullet.gif" : "~/images/icons/DashBoard_Red_Bullet.gif" %>' />

<asp:HyperLink ID="HyperLinkWorkOrderSummery" runat="server"
NavigateUrl='<%# "~/AuthUser/WorkOrder_Main.aspx?Id=" + HttpUtility.UrlEncode(DataBinder.Eval(Container.DataItem,"Id").ToString()) + "&mode=View" %>' > <%#Convert.ToDateTime(Eval("StartDate")).ToShortDateString().ToString() + " ," %>
</asp:HyperLink>
</ItemTemplate>

Using a code behind custom method



<ItemTemplate>
<asp:Label ID="LabelPublicComment" runat="server" ToolTip='<%# Eval("PublicComment") %>'
Text='<%# FormatName(DataBinder.Eval(Container.DataItem, "PublicComment")).ToString() %>'>
</asp:Label>
</ItemTemplate>


Write this method in code behind

protected string FormatName(object description)
{
string desc = Convert.ToString(description);
if (desc.Length > 25)
return desc.Substring(0, 25) + "..";
else
return desc;
}

How to find the control that caused the Page Submit in FormLoad event - ASP.NET

This function would be useful when someone needs to identify button clicks outside the respective button event
Changing the selected object type, it's possible to find other controls as well.


public static System.Web.UI.Control GetPostbackControlObject(System.Web.UI.Page pageReference)
{
System.Web.UI.Control returnObj = null;
if (pageReference.IsPostBack)
{
//- Find postback control's Name in form __EVENTTARGET field...
object eventTarget = pageReference.Request.Form["__EVENTTARGET"];
//- if __EVENTTARGET has a value (not null or an empty string), return the control with that name
if ((eventTarget != null) && eventTarget.ToString().Trim().Count()>0)
{
return pageReference.FindControl(eventTarget.ToString().Trim());
}
//- That is not working if the postback is trigered by a standard Buttons.
// Get the control from the Page.Form collection.
foreach (string keyName in pageReference.Request.Form)
{
System.Web.UI.Control selectedControl = pageReference.FindControl(keyName);
// Found & a Button
if ((selectedControl != null) && (selectedControl is Button))
{
returnObj = selectedControl;
break;
}
}
}
return returnObj;
}
