Data Controls :: How To Create Dynamic Buttons On Click Of Dynamic Button
Jul 24, 2013
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
I want to create dynamic buttons on button click event(for example., btnCreateDynamic_Click).
I tried creating dynamic buttons on page_load event and Pre_int event.They are all working but i want to create them in button click event. How can i do this in c# asp.net?
I have asp.net page on which I have placeholder and a button. After the button is clicked I want several LinkButtons to appear on my placeholder, and I want specyfic handler to be connected to click_event of my LinkButtons. Here is the code:
protected void Button_Click(object sender, EventArgs e) { for(...) { LinkButton l = new LinkButton(); l.ID = "link" + i; l.Command += new CommandEventHandler(link_Command); PlaceHolder1.Controls.Add(l); } } void link_Command(object sender, CommandEventArgs e) { PlaceHolder1.Controls.Clear(); Label l = new Label(); l.Text = e.CommandArgument.ToString(); PlaceHolder1.Controls.Add(l); }
The LinkButtons will be visible but their event won't fire. How should I solve this? I need to generate LinkButtons inside the Button_Click event, because only then I will know how many buttons to create.
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.
I have a dynamic Table which contain 8 rows and 8 Colums
Table t = new Table(); TableRow rr = new TableRow(); TableCell cc = new TableCell(); and in the each Cell CC I add a dynamic Button(Or Linkbtn) LinkButton LB1 = new LinkButton(); LB1.Text = "AM"; LB1.ID ="Link1"; cc.Controls.Add(LB1); rr.Cells.Add(cc); LB1.Click += new EventHandler(LB1_Click); t.Rows.Add(rr);
i have a table with 8 rows , 8 colums and each cell contain a LinkButton (which diffrent in IDs) I want to add Lable in the same cell of this LinkBtn(LB1) which it clicked but I cann't What shoud I write here?
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 a project where I need to create menu buttons from a list in SQL Server. The problem I am having is that I need to add code to the text of those buttons. So there would be a birthday button and it should display the number of birthdays within the next two weeks or a button with the number of upcoming events.
Clarification:
There is no code yet, just some requirements. What I am doing is querying a table to get the list of buttons to display. Now each of these buttons may have dynamic text, for things like count of birthdays, events,etc... I am trying to see what the best way would be to handle this. Should I embed a snippet of code to go along with the menu item to execute when I iterate over the menu items? Maybe I should build a javascript file to go along with the code, which I add code to query a service for certain menu items?
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?
the buttons are created fine, when i click a button i get my javascript alert, but my labels arent updated, its like the serverside function isnt running it at all
the "SetTemplateContent" section the aspx section is at the bottom if that helps
whats up with the code that would be great, cheers
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 created a web form in which i have used user control there is link button on different link button user control loads . i have added dynamically webcontrol to that link button . they are loading properly but when i try to save data through one of user control on click of button the user control disapper from that place but when i put static user control to my page its working
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 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...
I have a html table, which I created dynamically. I can add rows at run time in it.In each row I have a file upload control and an upload button by side of it in a cell.I want to know how can I handle the click event of these buttons because they are generated in a for loop dynamically.
1st row ... | btn | if a new row is added, 2nd row will be visible.
I'm customizing a NopCommerce store, and am using a gridview to display and sort the products. All that works well. I like how the external pager (user control) works with the gridview, with one exception -- it uses the hyperlink control, so I lost viewstate, which I need to retain for both the search page and to retain the gridview sort options. Based on the page selected (from the pager control), I query the database and rebind the gridview. So, I switched the user control to use LinkButtons instead of Hyperlinks. This is the sample code for one of the buttons:

I set a breakpoint inside the lbCommandClick method, but it never gets hit. Reading other posts tells me that I would have to add the dynamic controls in the OnLoad method, but since this all happens based on other data on the page (say search results), I don't think I can do it onLoad. However, the link buttons do work to cause a postback, and my viewstate is saved correctly. The only problem is that I do not know which button was clicked. I could check Request.Params["__EVENTTARGET"] onLoad, but that is kind of a hack -- I'd much rather be able to set the event handler in the user control and use the CommandArgument property. But, what I have tried so far fails.
Especially one that would allow me to set the EventHandler in the User Control? (e.g. OnlbCommand="PagerLBPageChange" )
I am adding some dynamic image buttons to a form in my code behind (vb.net) and added a click event handler, but it never fires. Also when I click on a button the page posts back and everything below my update panel disappears.
How should I go about removing dynamic control.I have a method that does the removing currently, however, it doesn't remove when postback..Here's my code
