I want to raise an checkbox check-changed event but its not firing :( . It Dosent raise even an command event.
My Requirement :
My Requirement is that i have a Datalist with header checkbox in headertemplate and a child checkbox in itemtemplate and a gridview control. Checking and unchecking will update the gridview control.
I've been reading up on the problems with dynamically created controls and how they have been solved. The posts I have come across are creating the controls in a panel or some other open place. I can't seem to get my checkbox to fire the event from inside a gridview. below is the code behind from inside the GridView PreRender event.
[Code]....
..And the Checked Event..
[Code]....
So after all this, nothing happens. I get the postback flash but my command inside the checked event doesn't fire.I tried putting the dynamic creation of the checkbox in Page Load with no effect.. I think because I can't place the checkbox inside the GridView under page load.
I have the below label. I need it to be a link that will cause the following:
Existing label INSIDE a DataList Item Template;
<asp:Label ID="Label10" runat="server" Text='<%# Eval("CG_ID") %>' Font-Size="X-Small"></asp:Label>
I need to change this label to a link that will cause C# code behind to:
tbxCG_ID.Text = Eval("CG_ID")
and then call this:
protected void ListBox1_SelectedValueChanged(object sender, EventArgs e)
I keep creating a DataList1_SelectedIndex_Changed event created when I double click the label or a link button. What is the code needed? I can see the Eval("CG_ID") value with the label but I don't know how to get it into tbxCG_ID.Text and fire the ListBox1 event.

what are the events fired during gridview loading,,,,,,,,,,?
View 1 RepliesWhy is it that the aspx.net system fires all the TextChanged event (for a slider) to a value of 0, when you did not originally set any values?
What I notice happening is, if you do not declare a Slider1.Text = "0" value initially, then when the page_load fires, the control protected void Slider1_TextChanged is fired automatically.
I have a user control called ucTriStateButton. It raises an event when it is clicked, called TriStateButtonClicked. If I put this user control on a page, it works fine. Here is the declaration on the .aspx page:
[Code]....
When the button is clicked the method tsbTest_TriStateButtonClicked executes correctly.
The problem is when I put the user control in template field of a GridView.
[Code]....
There is no way to hook the event handler to the control in Page_Load because I cannot get a reference to tsbMorning. So I did it in the RowDataBound event handler of the GridView, where I also do a bunch of other row-specific stuff. Although this builds and runs, the event is never actually subscribed to and so never gets fired.
So the question is - how can I handle an event from many instances of the same user control within a GridView? I am calling the same bit of code regardless of which user control is actually clicked. I only need to know that one was clicked.
I am building my first user control and am facing the following issue: my host page calls the user control:
protected
void DropDownList1_SelectedIndexChanged(object sender,
EventArgs e)
{
TextBoxRegExValidator1.DataTypeId = DropDownList1.SelectedValue;
}
I pass a string value (1,2,3,etc) via public method called "DataTypeId". The problem is that all the events in the control are fired first so dataTypeId is always null:
[Code]....
I am sure there are many ways to achieve my goal but since I am a beginner I dont know what they are. All I am trying to do is to have a user control TextBox which will work with a Listbox in a host page. The listbox will pass the data(1 - String; 2 - Xml) and so on. Then I change the regular expression in the user control and return that to the form. If there is an easier way to do that or a sample control out there which achieves the same goal.
I want to select all checkBox in Gridview when click to header checkBox.I have created design such that CheckBox is not available to header of Gridview.It is in other table. Below is design of gridview.

OnSelectedIndexChanged event for the dropdown is the fired.
I have set the autopost back value = "true", EnableViewState ="true" for page tag and gridview tag.
Iam finding the button control which is inside the Footer Template of Data list control.
i tried the below code but it is not working suggest me where iam doing wrong or how i find the control avaiable in footer template of Data list.

In code-behind, I can successfully refer to ID XXX if my ascx file looks like this:
<%@ Control Language="C#" AutoEventWireup="true" CodeFile="ProductsList.ascx.cs" Inherits="UserControls_ProductsList" %>
<div id="XXX" runat="server"></div>
But if the Div ID is embedded within a DataList control(below), XXX becomes unrecogined in code-behind:
<%@ Control Language="C#" AutoEventWireup="true" CodeFile="ProductsList.ascx.cs" Inherits="UserControls_ProductsList" %>
<asp:DataList ID="list" runat="server" RepeatColumns="3">
<ItemTemplate>
<div id="XXX" runat="server"></div>
</ItemTemplate>
</asp:DataList>
How can I successfully refer to HTML ID's embedded within a DataList contol?

How to moidfy the above article by include dropdownlist getting data from a database table.
then filter the datalist using the selected value of dropdownlist. and then print only records that are selected by checkbox.
when form loads the datalistcontrol should display all the records.
I'm currently facing an annoying problem that i can't seem to figure out. I have a gridview in my page, and i wanted to add a second header row to it. Well, i did that without any problems using the code below.
No problems so far. I then intended to add some filter to my gridview and so added a dropdown list in this second header i had created.
I simply added the control i previously had to my cell of the header.
[Code]....
The problem is that now, the SelectedValueChanged event is not firing when i change the value on my dropdown list. If i place her out of the gridview, the event fires normally, when placed inside the gridview the event apparently stops firing.
I have tried this with and without AutoPostback ON, though the final goal would be to have that option on OFF. (The postback would be caused by some other button on the same second header row, allowing the user to combine multiple filters simultaneosly)
