Data Controls :: Dynamic Image Button Inside GridView Not Firing Click Event
Apr 9, 2014
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();
[Code]...
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
}
I have a GridView control bound to an AccessDataSource. After selecting a row I'm creating a table inside the selected row. I'm adding Buttons to this table. Their Click event never gets fired. I read about recreating the buttons and stuff, but still no luck solving the issue.
Button 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. For this button i have written a click event in code behind.
How to read values of asp: table in grid view after binding.
I want to get values one by one in label in for loop and read values of table row one by one.
Like if i put check box in gridview and the row which is selected , i want to read value that asp:table in gridview.
How I bind grid, code attached.
Private Sub gvTransactionsBind(ByVal qry As String) Dim adp As New SqlDataAdapter(qry, ConString) adp.SelectCommand.CommandType = CommandType.Text Dim ds As New DataSet adp.Fill(ds) gvTransactions.DataSource = ds
I have an UpdatePanel with a GridView. This GridView has a template column that is a DropDownList. The problem is that the SelectedIndexChanged event does not fire for the DropDownList. Here is the code:
I have a ImageButton inside a gridview. The gridview is inside update panel. i want to redirect to another page with the Clicking of the ImageButton. But it is not working inside update panel. what should i do?
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 am trying to create a custom GridView with a header toolbar at the top that will contain icons to export the grid view to different formats like excel, word, etc.. The problem is, I cannot get the method to fire that is assigned to handle the click event for the corresponding Image Button. The page posts back, but the code I have in the method to handle the click event does not fire. I have followed examples in other posts and from what I can tell I have followed what others have done. Can somebody take a look at see if they can find something that I am doing wrong.
I'm creating a next/previous function for my repeater using pageddatasource. I added the link button control dynamically in my oninit using the following code.
LinkButton lnkNext = new LinkButton(); lnkNext.Text = "Next"; lnkNext.Click += new EventHandler(NextPage); if (currentPage != objPagedDataSource.PageCount)
[Code]....
So I am incrementing the cookie I am using to track the page number and then rebinding the repeater.
Here is the main issue. The first time I click Next, it works, it goes to Page 2 without any problems. When on Page 2, I click Next, it goes back to Page 1. Seems like the Next event is not wiring up properly.
Problem : I have Added One Link button to the above Table.. Click Event for That Link Button Is not Firing Now. when i click on link button of table event is not firing at all.
I have page (inheriting from master page) in which I have a dynamic Grid view (columns are not defined at design time), but gird is binded from xml at run time.
From code behind, I am adding a LinkButton into a single column in Gridview as
[code]....
But when I click on the link button, it does a post back, but the Click Handler is not called? Also in the same page i have an asp:button, from javascript I am doing document.getElementByID('someid').click(), this also causes a postback but the button click handler on server is not invoked?
I am having an odd situation with a dynamic image button. This button is part of a dynamically built asp table which lives in a repeater. Not sure if that complicates things or not, but here's the issue. Since the buttons are dynamically built, if I let asp.net handle the ids I get a crash on postback. Not entirely sure why, but If I set the id in code, I don't get the duplicate id error but I don't get the event fired either. Here is the code building the button:

With this code the IB_Validate_Click never fires. If I comment out the IB_Validate.ID line, the event fires. But, as mentioned above, I have an id clash on a postback. Any ideas why the IB_Validate_Click doesn't fire on this button if the id is set?
I have a webfrom on which I have some textbox controls, validation controls and button controls. When I click the button is validating the form but when I fill the text boxes with valid data and click the button nothing is happening i.e. the page is not posting back and button_onclick event is not firing. Below is the markup.
I have Onclientclick event attached to the button in serverside code like below,TopPanelButton.OnClientClick = string.Format("if(!ValidData({0},{1},{2},{3})) return false;", txtOD.ClientID, radCmbOD.ClientID, txtgetMe.ClientID, RadAjaxLoadingPanel1.ClientID);Also, the onClick event is attached for the same button in the aspx page,
The serverside click event should fire if the onclientclick return true. The "ValidateData()" function is called to validate the entries in the form.This code is working fine in IE. But in Firefox, both events are not firig. If I comment the "TopPanelButton.OnClientClick =..." code then onClick event is firing.
i want to upload mp3 songs and also download it....
i got code from our partner site and it is useful but when i click on upload button then it doesnt go to that click event so that code is not working...
my code is:=
protected void mpsong_button_click(object sender, EventArgs e) { using (BinaryReader br = new BinaryReader(FileUpload1.PostedFile.InputStream)) { byte[] bytes = br.ReadBytes((int)FileUpload1.PostedFile.InputStream.Length); { {
My guess is that it is due to the hierarchy/load order:
In English: Inside the page's Load, it adds a user control. Inside of that user control, inside of Page_LoadComplete (is this the issue!?), it adds another user control, it is the inner-most user control that contains the mark-up button.
Pseudo Visually: Page -> Page_Load: Dynamically Added User Control -> Page_LoadComplete: Another Dynamically Added User Control -> User Control Mark-Up: Button with event.
Do events need to be hooked before LoadComplete? (Is there a way to make events still work even though the controls are added in LoadComplete?)
I have a master page containing a ScriptManager control, and a Content Page containing a ScriptManagerProxy Control. Further on the content page I have an UpdatePanel control containing a GridView control and a server side button control. I have registered the button control as a trigger with the UpdatePanel control asynchronously and have set the UpdateMode of the UpdatePanel to "Conditional". I also have a "JumpLoader" control which is outside the UpdatePanel control. I have the following event for Jumploader wired up through Javascript. I am pasting the relevant sections of the code below:
I have textboxes being generated by a repeater that use OnTextChanged with autopostback enabled so that I can know when when the values change. This all works perfect.The problem starts when I try to click on any buttons on the page. The loss of focus triggers the event for the OnTextChanged; however, the event for my buttons never get fired. I checked this in the debugger and while debugging if I put a break-point in the page_load it will call both; however, without the break-point it still only calls the OnTextChanged event.I found this post on JavaScript. If my problem is also JavaScript related, why does the clicking of the button fire in debug mode?
