Hi,
Sorry for the delay...there was a problem in the site..
You need to raise an event to the page. Here is how to do it.
First let’s create delegate and define an event of type of the delegate. And call that event in the button click event.
Add this code your ascx.cs file
public delegate void LoadGridHandler();
public event LoadGridHandler LoadGrid;
protected void Button1_Click(object sender, EventArgs e)
{
this.LoadGrid();
}
Now, in your aspx file, raise that event during the page load of your page.
Take this code..
protected void Page_Load(object sender, EventArgs e)
{
MyControl1.LoadGrid += new Controls_MyControl.LoadGridHandler(MyControl1_LoadGrid);
}
void MyControl1_LoadGrid()
{
//write the method to load you grid
Response.Write("Hi from Gayani");
}
Hope it works
Thx,
Gayani

Hello!
I've got an aspx-file which I use for AJAX to return different stuff depending on querystring. I one case I return an webusercontrol(.ascx) with a bunch of controls including a couple of validators. When I try to do this:
myWebUserControl.RenderControl(myHtmlTextWriter)
none of the asp:validator-controls gets rendered in html. This includes asp:RequiredFieldValidator and asp:ValidationSummary. What do I have to do in order for those controls to also be rendered?
|
|
|
|
|
In design mode drag the .ascx onto the form. put the control inside a panel
in the page load set panel.style.value = "display:none";
in ajax event when you want to display the ascx set panel.style.value = "";
Did that help?
I didn't get any requirements for the signature

Hello and thanks for your reply! Actually this did solve part of the problem. Now I do get html for the validators like this:
span id="Login1_validatorReqFieldUserName" style="color: Red; display: none;"
but I don´t seem to get the javascripts that makes the actual validation work.

check this out:

your error is a big clue, which line of the code does it have a problem with, is it this line:
TextBox1.Text = cClass.dataReader.Item("Type").ToString

yeah i put my class in App_Code folder....should i make dll for my class...i didn't make that....please help me
|
|
|
|

It depends how your website functions.
Have you previously copied a dll across?
I know that if you write the c# in visual studio and then upload dll then the most updated pages of code must be in that dll
To answer your question then yes put it in the dll
