Web Forms :: Capturing Data From Dynamic Controls On Button Click
Dec 29, 2010
I've created a number of identical controls in a varying number depending on how many employees are under a supervisor. What I am trying to do now is to see which set of controls are checked via a checkbox and return a value from the label field in that particular set. Here is my code:
[Code]....
What I am trying to grab in particualr is the PayRoll Label. I've named sequentially as "lblPayRoll" + the counter. Which from what I think I should be able to do is get the total count of my array and from then loop through the controls and grab the label data.
Problem is that I can get the data, but it disappears after I click the button to grab it. I think I am saving everything to the viewstate, but they just disappear.
im creating dynamic buttons on page load and on the click event of button1 handlere iam creating more buttons this is going fine but on click event of button 2 work is not done so how to maintain a chain of creation of button on click events
The data is populated in the gridview dynamically at runtime The number of rows vary each time The auto postback event has been set to true I need to capture the rows that are selected, When I try to capture the button click event; the gridview is null(I understand that it has to be rebound on each postback). Hence this is not working
[Code]....
I also tried this, the rowcommand event; It is also not getting generated. The gridview rowcommand is not getting fired

I need the rows which are selected using the checkbox in the above mentioned sceanrio.
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.

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 work with dynamic webuser controls. Depending on a choice in a dropdownlist, I load the webuser controls from my database. In the Page_Load event, I load the controls. When the controls are loaded and a button is pressed, the values that are filled in,in the webuser controls' textboxes, must be saved in the database. when I click the button, the values of the textboxes are empty again. Here's my code:

i have a web form in which i ve a button which will open a sliding pop up box(jquery) on click of it. In the same page i ve also a linkbutton for downloading files. Now the problem is first time wen i click that button it does nothing. (will not open popup box). Once i click on download button and then if i click that button it will open popup box along with download dialog box. Why is it happening so... is it because am using same event click for both these.
but download option is implemented in gridview_rowcommand()..
I am working on an ASP.NET web application using .net 4.0 and VS2010.
I have a GridView and I am appending a row at the bottom to allow users to input data for "Adding" a new record.
The ONLY way I have found for this to work is to do this in the RowDataBound event of the grid. I can check to see if it is about to process the footer row then I know I am at the bottom and can insert this new row.
The row I am inserting contains a couple of TextBoxes and a LinkButton for the "Add" link.
If I just drop a LinkButton on my form and hook up the click event and I click the link button then the first thing that fires is the Page_Load event then my click event. However what is happening when I click the link button that was dynamically added to the GridView is the Page_Load event fires but the click event never does.
I have read 1000 threads saying to try to create the controls in the preinit() or some other event. In my case I can't. Or else someone would have to explain how to add the row to the bottom of the databound GridView.
Here is my code: (I removed creating the Textboxes because that is not part of the problem.
I'm trying to fix a problem with some code (not written by me)
lnkbtnPageNumber.ID = "PageNumberCustomerRef" + intPageNumber.ToString(); lnkbtnPageNumber.Command += new CommandEventHandler(lnkbtnPageNumber_Command); lnkbtnPageNumber.CommandName = "DepotRef"; lnkbtnPageNumber.CommandArgument = intPageNumber.ToString(); lnkbtnPageNumber.Text = intPageNumber.ToString().PadLeft(3, '0'); lnkbtnPageNumber.Attributes.Add("style", "margin: 2px;"); pDepotRefPages.Controls.Add(lnkbtnPageNumber); This code creates a link button, however when I click on the button on the page. The function lnkbtnPageNumber_Command is not being called. The scripts just not getting to it. I've tried google but everywhere I've looked says that this code should work fine. Here is the code which is being called by the function: void lnkbtnPageNumber_Command(object sender, CommandEventArgs e) { try { switch (e.CommandName) { case "GlobalID": gintDocketNumberPage = Convert.ToInt32(e.CommandArgument); break; case "CreatedDate": gintCreationDatePage = Convert.ToInt32(e.CommandArgument); break; case "Accounts": gintAccountPage = Convert.ToInt32(e.CommandArgument); break; case "CustomerRef": gintCustomerRef = Convert.ToInt32(e.CommandArgument); break; case "DepotRef": gintDepotRef = Convert.ToInt32(e.CommandArgument); break; default: gintDocketNumberPage = Convert.ToInt32(e.CommandArgument); break; }
I've just read somewhere that this code won't work unless called from Page_Init which if true is a but of a pain cos I can't put this fuction in Page_Init...

All details are displayed except the hyperlink field.Has anybody any ideas as to what I'm doing wrong? The code is as follows:
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.
