Web Forms :: Values In Dynamic Webuser Controls Are Lost When Button Click?
Mar 16, 2010
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'm jquery ajax for cascading dropdown operations is works well.but my problem is whenever the button the clicked the second dropdown values is lost .......
note : i have placed two dropdownlist one for binding the class bind from server side code and second dropdown is for binding the division from client side using jquery ajax...

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.
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?

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 dropdown on page, a place holder and a save button on my form.Now, I am creating a textbox on selectedIndexChanged event of dropdown list and adding it to placeholder. And on button click I want to access the control, but on click event, I find the textbox as null. Here is my code

I have One DataList in their three columns ID, FirstName and LastName, when I select ID then I want to access the value of ID how to get the value of selected ID.
I have a page to wich I had several controls dynamically. When the page is posted back via Ajax, the values of the dynamically control do not make it server side. However, everything works well if the page is posted back in the normal way ( without Ajax).
I need the post back to be done via Ajax because I need to use the Callback function to perform other tasks in the UI once the call returns.I found this excellent article but it doesn't discuss ajax:
I have a listbox and textbox in asp.net c# languageI need to add the sum of all values in to a listbox using text box , when i enter something it will add list box and again i will do the same flow it will come one by one .
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...

Then, in master grid, I select a buttonfiled in a row to load the second gridview.Every thing alright, the second grid has it's row id But The master grid lost all row id that I dont know the reason why?
I am having gridview and i have check box for each row. There are 2 buttons ,accept and reject outside the gridview. If I click accept button, all the checked rows fields value should change to accept and if i click reject button all the checked rows column value should change to reject.
