Forms Data Controls :: Handling Events From A User Control Inside A GridView?
Jun 4, 2010
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 have a User Control which consists of a TextBox with a few extras, but for purposes of this example just assuming it's a plain TextBox will be sufficient. I am calling this User Control from a Web Form and would like to be able to use a RequiredFieldValidator that basically would function the same as if I used it on a TextBox on the web form. How do I configure my User Control to handle this?
EDIT:
DatePicker.ascx
<asp:TextBox runat="server" ID="myControlTB">
DatePicker.ascx.cs
[ValidationProperty("Text")]
public partial class DatePicker : System.Web.UI.UserControl

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.

In a gridview I have a TemplateField containing an imageButton defined as:
<asp:TemplateField>
<HeaderTemplate>
HeaderName
</HeaderTemplate>
<HeaderStyle HorizontalAlign="Center" />
<ItemTemplate>
<asp:ImageButton ID="imgName" ImageUrl="./img/img.png" runat="server" style="cursor: crosshair;" OnClick="imgName_Click" />
</ItemTemplate>.......
Now the odd thing at run-time is, whenever a client-side mouseover event is triggered, the app does a full postback. That happens only in firefox.

How to wire up HTML server controls events?
I added a Input (Text) control in my web form and turned it into an HTML server control so its an instance of HtmlInputText class.
If I double click on the control It only adds a OnClick event handler method inside the script tags in the HTML doc of the web form but how to I get to handle its Serverchange event exactly? does VS.net 2008 has no ability to auto wire up the event to the control, do I have to manually wire up the event handler?

I have a ObjectDataSource and a ListView referencing it.
I have created a Templated User Control (see:
http://msdn.microsoft.com/en-us/library/36574bf6.aspx) and placed it in the ListView's InsertItemTemplate
It has one template <ContentTemplate>. Inside that template, I've defined a couple of server controls with their properties = '<%# Bind("colName") #>'.
See below:

I've googled a bit for the exact order of all gridview events relative to and where inbetween page events. The only Microsoft article: [URL] is not very clear. I'm especially interested in the gridview row_command event relative to page events.

I have a GridView with a BoundField column and quite a few item templates like the following:
<asp:GridView ID="gvUsers" runat="server" AutoGenerateColumns="False" OnRowCommand="gvUsers_RowCommand"
OnRowDataBound="gvUsers_RowDataBound" DataKeyNames="UserId" OnRowEditing="gvUsers_OnRowEditing"
OnRowUpdating="gvUsers_OnRowUpdating" OnRowUpdated="gvUsers_OnRowUpdated"
DataSourceID="DataSource1" Width="807px" Height="105px"
[Code]....
While handling the Edit link button I need to use the value in the BoundField, UserName. Unfortunately during the OnRowEditing handler, all strings are empty "". This is also true in the ensuing OnRowDataBound handler for the row in question where e.Row.RowState == DataControlRowState.Edit. Is there a way to obtain this value after the user clicks on the Edit link, and commences the OnRowEditing event?

I have an ASP.NET 4.0 application with some simple user controls. The user controls work fine on the design surface (VS.NET 2010), but when they're loaded during application execution, nothing shows up.
Futhermore, the various child controls of the user controls are null when referenced inside the code behind for the user control.
The code behind for the user control executes as expected, but any reference to child controls are null.
It's like ASP.NET is never parsing the ASCX to create the instances of the child controls.

I am programatically adding a control to an aspx page and binding a server side event to an index changed event inside the control. (It's a RadListBox from Telerik's ASP.NET controls) The problem is that on the postback triggered from the control, the event doesn't hit its eventhandler because on the postback the control isn't defined. Is there a way to handle this without having to retrace the logic taken before and rebuild the controls so the events that stem from it are processed?

I created a customDropdown usercontrol with Events and It worked fine.
Now I stored the path of the ascx file in the database table and i want to Load the ascx file and handle the Events dynamically in an aspx page.
To Load the usercontrol and access the public properties and method, I need to know the object i am trying to load, right?
For Example
FeaturedDDL c = (FeaturedDDL)Page.LoadControl("~/FeaturedDDL.ascx").
But I dont want to hardcode objectType "FeaturedDDL", coz i dont have that stored in my Database field.
Since I am loading the usercontrol by getting the path and name of the usercontrol from the database table,how will I know the ObjectType at that time?
How to accomplish that and also how to handle the events for these type of situation?

I have a ListView control on a page that I need to support inline editing and inserting. Before I put it inside an update panel, everything was fine. As soon as I put it in an update panel, I seem to lose theOnItemUpdating, OnItemCanceling events. The OnItemEding event still fires, though.I am doing all updating, inserting manually.
