I have a eventhandler in code behind of a UserControl.
[Code]....
This one gets called from Page_Init
When i embed it directly into an aspx page it works as intended. But when i add the control to antoher control which is embed into an aspx page. The event suddenly doesn't fire.
aspx->usercontrol->usercontrol.
I'm adding a Button to a TableCell dymanically in code-behind and cant get an event handler to work.
Here's some code...
...
TableCell tc = some TableCell....
Button b = new
Button();
b.Text = "Go";
b.Click += new
EventHandler(OnSequenceChanged);
...
protected void OnSequenceChanged(object Sender,
EventArgs Args)
{
}
I set a break at OnSequenceChanged, but it doesnt hit when I click the button. It posts back - Page-Load gets called - but its event handler doesnt get called.
standard webcontrol:
<asp:Button ID="cb_btnSubmitData" Text="Submit data" OnClick="SubmitData_Click" runat="server" />
added this in the Page_Load eventhandler
this.cb_btnSubmitData.Attributes.Add("onclick", "addTextToLabel('message', '" + this.cb_btnSubmitData.ClientID + "');return true;");
and this is the javascript that is executed when the button is pressed:
<script type="text/javascript">
In the UserControl I am adding dynamic ImageButtons depending on the condition When the page loads and I click on Edit button I have no problems and btnEdit_Click is fired. But after that (btnEdit id removed and btnSave is added) when I click on btnSave the btnSave_Click event does not fire. What could be the problem?

I am trying to dynamically load query form as a user control and build a sql statement based on user selection. I have a dropdownbox for Tablename, FieldName, ConditionalOperators and Value Field. Once the user makes a choice and causes a postback I loose my QueryForm (UserControl) and the selection Changed event never gets fired. I tried reloading the QueryForm on Page Init, still no luck.

I've been looking at google for the past few hours, trying to find an issue to a apparently simple problem. I have a UserControl named RolloverLink that basically contains a asp:LinkButton and a <img /> . I tried setting the OnClick handler like this:

I put a breakpoint in the propagate method, but it doesnt stop there. The page does post back (it flashes), but the event doesn't get called.
Here's how my code behind looks like:

I create dynamic radiobuttons and want to add an eventhandler to them. What I have now doesn't work.
[Code]....
On page load I have this:
LinkButton1.Attributes.Add("onclick", "window.open('EditClients.aspx','','height=700,width=600');return false")
I also have an event handler for LinkButton1:
Protected Sub LinkButton1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles LinkButton1.Click
Label8.Visible = True
RefreshButton.Visible = True
End Sub
The problem is the event handler is ignored. Label8 and RefreshButton do not becoem visible when clicking Linkbutton1, but the new window opens fine. How can I make all things happen?
A new route to an old problem for me... I'm creating radiobuttonlists and adding them to an update panel dynamically using this code:
[Code]....
I'm wanting to get the selected radio button value whenever a button on the page is pressed, however (and this is my old problem) I cannot retrieve that value. What I'm wanting to try is to add an event that will record the chosen radio button whenever the selected value has changed and store it into an array.
write the custom eventhandler for a radiobuttonlist's SelectedIndexChanged, which was creating dynamically during runtime.

View 2 Repliesim creating site with usercontrols. I have repeater, inside it is another repeater with usercontrol. My problem is passing BindedValue to usercontrol.Bindings works fine and binds the value i need but it cannot pass the value to usercontrol. When i type it manually it works, when i bind it, it passes null (!).I've tried get,set, functions (ondatabound, onload, oninit), accessing control from code with no luck. Ive read and tried to do all the google solutions but with no luck. (even with creating usercontrol inheritance)
View 5 RepliesThere are 2 UserControls UC1 and UC2, and there is one more class C. I want to share the same instance of c in both UserControls. I know that this can be possible with properties in both UC's and by registering UC2 in UC1 or vice versa. But I want the solution to be loosely coupled. Any best possible way without touching the Actual Page (which hosts UC's)? So i need some best possible way between UCs transfering C.
View 5 RepliesI am banging my head with gridview at the moment. There's a problem I just can't get my head around. I'd be very greatful for any advice given. I have a function that creates a DataTable with three columns and four rows. In each of the cells I set the text to a random number through RowDataBound event. I would like to just make the cell clickable and have a code-behind function that gets the position of the cell (column, row) and the value of the cell when the user clicks it.

have a webpage that has a button and 2 userControl placed inside the placeHolder with visible set to false.When run and click on the button, userControl1 will set the visible to true. Now userControl1 is visible and there is also a button inside this userControl1 and when click, will set userControl2 visible to true and hide userControl1. The code below is the code behide for the webpage the do the above task.
[Code]....
Is there a way to do so that when click on the button inside userControl1, is does not show userControl2? I want to do this way is because, the button is for submitting data to database and then will pop up userControl2. When there is an error, only a msgBox will pop up and does not show userControl2.
i have create two linkbuttons dynamically:
for (int i = 0; i < 2; i++)
{
LinkButton lb = new LinkButton();
[code]...
The scenerio is I have a UserControl. This user control will create dynamically ListBoxes if the given List's count > 0. The controls are adding dynamically, there is no problem with adding them, but the event handler is not adding. If I select an item in first listBox, the secondListBox will be added dynamically, and items will add dynamically too. First listBox appears, but the selectedIndexChanged event handler doesn't work. What can be the problem with my code?
EDIT: I tried to add
li.Attributes.Add("onselectedindexchanged","selectedIndexChanged");
or
li.AutoPostBack = true;
but still not firing...
private List<string> myList = new List<string>() { "Serkan", "Kadir" };
private List<string> mySecondList = new List<string>() { "Istanbul", "Ankara" };
protected void Page_Load(object sender, EventArgs e)
