View 1 RepliesI have update panel in which i have a label and a textbox and a button
I havwe a Radiobutton list which i am using In the asynchoronous postback trigger of the update panel.
In the Control Id of the trigger I have passed Radiobutton List Id and in the event name I am passing SelectedIndexChanged
But when I click the button no event is firing rest all is working fine.
Looking for the best technique on handling or at least some documentation showing an example.
Starting Page
Gridview control withing an update panel (also various controls used for filtering NOT IN UPDATE PANEL)
Databinding does not happen during page load.
Databinding is initiated when update panel trigger (asp:Button object) is clicked
Hyperlink column is added to returned records
Hyperlink posts to a separate page for detail for record which the hyperlink was clicked.
Second Page
While navigating via the browser back button to previous page (which contained the update panel and gridview) only the (various controls used for filtering) have retained state. The gridview is not shown (which is how the page loads initially when starting) How can I retain the state of the Gridview and add a step in the browser history all together?

My gridview is inside master page now in the link button used inside gridview for downloading, it is not downloading a file.
I followed this article : [URL] .....
It works in child pages, but when i use gridview inside master page and follow this article , it wont download a file. Here's my coding for beck end :
protected void DownloadFile(object sender, EventArgs e) {
try {
string filePath = (sender as LinkButton).CommandArgument;
Response.ContentType = "application/pdf";
Response.AppendHeader("Content-Disposition", "attachment; filename=" + Path.GetFileName(filePath));
Response.WriteFile(filePath);
Response.End();
} catch (Exception) {
throw;
} }
Rest coding in html is same as mentioned in article.
I have a user control which has a gridview with hidden fields in some of the template columns. The grid columns are created and bound by code dynamically in each postback and not in design mode. The gridview is placed in an update panel. In my aspx page where i use the user control , there is a dropdown which fires postback and based on the selected value of the dropdown the grid data gets filtered. The dropdown in aspx is not part of any update panel.
After the postback of dropdown, the grid data gets filtered and the grid is rebound with fresh values. The values in the controls like label, button or link button are bound correctly. But the values in the hidden fields are not refreshed and always points to the values of the rows that was generated before the postback of the page (initial page load).
If the gridview and print button are inside the update panel,then the print fuction is not calling.
If i place the print button outside the update panel then it is working fine.
I have a link button inside an update panel. The problem is the link button on postback is updating the whole page. Tried it with a normal button and the page is not refreshed all. Here's the code.

I have a control on a page. In the control's pre-render event I'm executing some code that's taking about a minute to execute. This means the whole page is unresponsive until the control's pre-render event is finished executing.I tried putting the control inside an update panel, but it doesn't matter the rest of the page still won't render until the pre-render event of the control is finished executing. I've attached a very simple example of my code (The event that's slowing up the control's pre-render event is not Thread.Sleep(1000):

I have a TabContainer with multiple Tabs. For some of the Tab's Button OnClick events work and on others they do not. I have dropdowns etc in each of these tabs and their SelectedIndex events fire. Just some of the button events don't fire. If I move the HTML and codebehind to a blank page for any of the Panels that don't work, the buttons work as expected.
View 7 RepliesI have many controls like dropdown, radiobuttonlist, etc on my page and I put all these controls inside the update panel so that the page doesn't look to be posting back when something is selected. Now the working on the page is very smooth. But the session object isn't getting refreshed even if I postback to the server and as a result even if the users are working on the page they are being sent to the login screen after 20 mins.
Is there anyway where I could put all the controls in update panel and still refresh the session after any postback(dropdown selection)
I am adding a click event (display alert on click) to a html hyperlink inside an UpdatePanel on document(ready). However, the event never gets fired when I click the hyperlink. Is it because of ASync postback? What is the correct way to do this?

I have a checkbox, textbox and requiredfieldvalidator inside the updatepanel. Once user checks selects
checkbox I am enabling requiredfieldvalidator.
I have one more textbox, requiredfieldvalidator, validationgroup and Linkbutton outside updatepanel.
Strange thing is Checkbox checked event not firing in some cases,
1. Check the checkbox (which enables requiredfieldvalidator)
2. Click the Linkbutton (fires two validators)
3. Uncheck the checkbox (which should disable requiredfieldvalidator)
4. Click the linkbutton again (again it fires two validator, which should fire only one validator)
Note: The problem only arising when I add javascript block to linkbutton in page load event.

I have an ASCX control which is a special dropdownlist. I add that control dynamically to the page and fill it with data. This control has a postback that will change the contents of a second dynamically created standard dropdownlist.
When I change the selection on the first dropdown, the indexchanged fires and I get new data and attempt to place it in the second dropdownlist's items collection, by first clearing it then filling it with new data.
This works fine the first time a change the selection, but when I select a second time the following error is thrown:
The control tree into which viewstate is being loaded must match the control tree that was used to save viewstate during the previous request.
I'm not adding or removing new controls in the fired event, only changing data. And again, it works the first time, but doesn't subsequent times.
If I disable stateview on the child control, then the control just doesn't get updated with data at all.
I am building a system for a school project. I currently have several Update Panels on the page that have many different controls on them. I also have a single Label control that i use to display messages to the user. I would like to have this label within an update panel also but there are literally hundreds of triggers that would require it to be updated and i dont want to type an absurd number of triggers for this one control.Is there a way for me to have this one panel update regardless of what happens?
View 2 RepliesButton click event from inside the accordion pane is not firing. Accordion pane contains tab container inside one of its panes (5th pane) to read data from user and to save that data into database. I have used a button to save data when user click on that button.

this is my click event
<asp:Button
ID="Save"
runat="server"

OnClick="Save_Click"/>
and code behind code

I have a GridView which has normal Edit/Update button. However, my GV RowUpdating, RowEditing & RowCancelingEdit is working with 2 clicks. If I am clicking it once, its not working :(
Here is the code where I am populating everything:
public partial class Testing : System.Web.UI.Page

string getEntity = Request.QueryString["EntityID"];

On grid RowDataBound based on some condition i've added imagebutton dynamically. parallelly i want to add event for this button click. here is my code snippet.
protected void GV3_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
TableCell cell = new TableCell();
ImageButton bttn = new ImageButton();

That message popup box comes, but i'm unable to catch that click event. while click on a row i want to delete that row, so want to create event dynamically. for that i've used this following dynamic click event
bttn.Click += new ImageClickEventHandler(b_Click);
private void b_Click(object sender, EventArgs e)
{
//delete record
}
but this above code also not working.
