Click Me in a UserControl. I downloaded the sample attached there and its working fine but i am trying to create UserControl out of it. No rows are getting loaded on scrolling down. I modified the code to look like this..
var lastProductId = $("#<%=Test1.GridView1.ClientID %> tr:last").children("td:first").html();
//get last table row in order to append the new products
var lastRow = $("#<%=Test1.GridView1.ClientID %> tr:last");
AND,
function GetRowsCount() {
//Count no. of rows except header row in the grid.
var rowCount = $('#<%=Test1.GridView1.ClientID %> tr').length - 1;
return rowCount;
Its giving me error: The name 'Test1' does not exist in the current context. Test1 is the Id of my USerControl. Test1 is the ID of UserControl. I found your tutorial on similar issue but i did not use it because i am not using stored procedure and i know nothing about XML. At this point i just want to make the sample attached in that article(one i provided) to work as a UserControl.

I am using a usercontrol which has two textboxes named txtUserName,txtPassword and a button named btnSubmit.I am using this usercontrol in my webpage.I want to show alert message in the webpage if the user didnot enter the username or password .
View 1 RepliesI am loading a control to a page dynamically with LoadControl("src to file"). In the usercontrol i have a validator and some other controls that i would like to access from my page. I canät get it to work, null pointer exception. Scenario is like this. I have a Edit.aspx page which loads the EditTemplate.ascx usercontroll. I would like to get information or find the controls in the EditTemplate from the Edit.aspx site. I have tried exposing the controls and validators as properties but how do i access them from my Edit.aspx?
Example code:
Edit.aspx, the control is later added into a
Control control = LoadControl("src to ascx");
TemplatePlaceHolder.Controls.Add(control);
EditTemplate.ascx
<asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server" ControlToValidate="CompanyImageFile" ErrorMessage="RequiredFieldValidator"></asp:RequiredFieldValidator>
CodeBehind
public partial class EditTemplate : System.Web.UI.UserControl, IEditTemplate {
public RequiredFieldValidator Validator {
get { return this.RequiredFieldValidator1; }
set { this.RequiredFieldValidator1 = value; }
}
From the Edit.aspx site i would like to check the validators isValid property. Isvalid is set in a Save method. The save button that saves the template is located in edit.aspx, so the post in done from that page. So the question is how to get a hold of the property from the usercontrol in the edit.aspx page, where and how should this be done?
I have the requirement to display the total of values entered in the textboxes inside the gridview.

</ItemTemplate>
</asp:TemplateField>
i need the sum of values entered in txtTotalPetitions(It is editable,not from the db)
