It seems like you are using a wrong hierarchy. You are putting the update panel direct under the template field?. Inside template field only templates has to be there. Inside the template you can have any fields.

                                               Text='<%#Eval("IsFresher")%>' runat="server"></asp:HyperLink>

My problem is not getting the value in Eval("Subject") in item template

Mahendra.p25 8-Apr-11 7:59am

Check in the DataSet table Column Name is Same as (Subject) or not and It has values in it or not.

i have tried this and its working <asp:LinkButton ID="LinkButton1" runat="server"><%#Eval("IsFresher")%>

Rajisha Aravind 8-Apr-11 8:03am

The dataset column name is also Subject and also it has values.But I can't understand the why don't get the value

Rajisha Aravind 9-Apr-11 1:11am

for checking,I give a textbox in itemtemplate with text.
ie,
<itemtemplate>
<asp:TextBox ID="TextBox1" runat="server" Text="Testing">

But even the textbox also not displaied

your link button end tag is missed:

<asp:linkbutton id="LinkButton1" runat="Server" commandname="Select" >
<%#Eval("Subject")%>

and if you call your bind method from repeter Item command or any other repeter event then one post back needed to bind it.

ScriptManager.RegisterStartupScript(this, this.GetType(), "Postback", "postback();", true);

javascript:

postback()
{
  _dopostback('LinkButton1','');
}

You may wrap in this hierarchy

XML

<asp:TemplateField>
    <ItemTemplate>
            <asp:UpdatePanel runat="server">
                <ContentTemplate>
                    <asp:LinkButton id="LinkButton1" runat="Server" CommandName="Select" ><%#Eval("Subject")%></asp:LinkButton>
                </ContentTemplate>
            </asp:UpdatePanel>
      </ItemTemplate>
</asp:TemplateField>

Put everything inside an outer item template. If the subject is present in your result set it supposed to be bound, else debug your data source

I gave the update panel with in the itemtemplate. But not get the value in linkbutton

Albin Abel 9-Apr-11 0:47am

That means your result doesn't has the subject. One of your previous replay says "In Pageload with in the (!ispostback) , I bind the datasource with the schedulecalendar", this means only one time the data source is available. when post back the grid will be empty. You need to debug the data source and check the datasource contains the necessary information.

Rajisha Aravind 9-Apr-11 1:00am

You say that the datasource available at one time.It fine . But at that time the dataset value could not bind in itemtemplate of schedulecalendar

Item template can't bind value
