AJAX :: Tab Container W/ Dynamically Added Tabs - Content Mixing On Postback
Mar 2, 2010I have a page with 4 fixed Tabs. Tabs 1 and 2 are always in position 1 and 2. However, the users are allowed to create their own tabs and add their own html content. I do this by creating a new tab in codebehind and inserting it into the tabcontainer AFTER the frist 2 and before the last 2 tabs. There could be several of these. EX: "F1 | F2 | U1 | U2 | U3 | F3 | F4" where F is a fixed tab and U is a custom tab.
As long as ALL tabs are visible then everything works fine after postbacks.
Based on user settings I sometimes hide fixed tab 1. Everything loads fine the first time. However, on postback The content on fixed tab 4 (always the last tab) is displayed on the bottom of EVERY tab (fixed or custom). It is still displayed in fixed tab 4.
A little background on the code:
Since the tabs are added dynamically they do not exist on postback and must be re-generated every time. This is done in Page_LoadComplete. I have tried it on PageLoad and it behaves the same way.
If I do not re-generate the pages on post back then the problem goes away - as do the custom tabs.
The only thing I could find was from last year, and was supposedly fixed (http://www.codeplex.com/AjaxControlToolkit/WorkItem/View.aspx?WorkItemId=16321
Web Forms :: New Entries Added To Listbox Not Appearing After Postback?
Oct 22, 2010I have added a listbox, and on page load I populate it with a few items. Then I have added Javascript code so that the client can click a button to add more items to the listbox. But when the page is postedback I am only left with the items that were loaded from the page load....
Is this the way .net operates?
I was reading that if I need to get all the items in the listbox, I will need to add a hidden field and write out the items in a CSV format, and then use that hidden field to work out the items in the listbox..

Web Forms :: Loop Dynamically Added Usercontrols?
Sep 27, 2010I am making a website where the user has to choose some addresses form a list of street names.
I have made a usercontrol Witch I dynamically adds to the website depending on some choices the user makes (Zip, and Streed name) The usercontrol contains a checkbox. When the user clicks a button on the site I would like to find all the usercontrols the user have checked.
The usercontrols is contained in a asp:Panel
I have tried with a foreach loop where I loop all the controls in the panel. It only retun one control.
Then I have tried with at ControlCollection ctrlCol = ContentPanel.Controls;
It only returns a LiteralControl. Then I have tried to loop all the controls on the webpage testing for the type as the usercontrol but no luck
How can I find an loop thru all my usercontrols and find the checked?

Web Forms :: Event Not Firing On Dynamically Added Control
Feb 23, 2011While I am using a "Telerik" control here it shouldn't be any different I guess;
[code]....
What happens is that the control is created and rendered;
When I change value in the Combo box a Post-Back happens.
HOWEVER, the event RadComboBoxSelectedIndexChanged does not fire. Also when I am back at the page the new value is not saved; Obviously, i recreate the control every time. If I don't I get a ViewState error. Seems to me that there some ViewState management problem, but I cannot identify it...

View 6 RepliesWeb Forms :: Persist Dynamically Added User Controls Between Postbacks?
May 6, 2010I have a C# web application that dynamically adds user controls to the default page for whatever "mode" the application is in. The problem is that it is not persisting these across postbacks. How do I persist these across postbacks and keep the content of the controls that are in the user control?
For instance, say I have a user control that creates a new tour record. The user clicks on the Tour item from the menu on the default page, it dynamically loads the tours user control. The user then fills out the form in the tours user control and clicks save. This is where the problem happens. When the postback occurs, the web application has no idea that the new tours user control was ever loaded. So, no save takes place because the Save button's click event never even gets fired.
Web Forms :: Page Min-height With Dynamically Added Content Not Working?
Mar 9, 2011I've made a pag with a content div that has min-height set to 1200 pixels, and a black bacgkround color..
When I add a bunch of lines in the .aspx page (in html) , it works perfectly, it changes the black background height to the required height if it was more than 1200 pixels.
But, if I put a PlaceHolder in side the content div, and add a bunch of lines
dynamically to the PlaceHolder, it doesn't work, the page shows the content with background of 1200 pixels of height, and at the bottom of it no more content background, but continues showing the rest of the lines
outside of the content div..

Web Forms :: Unable To Maintain Viewstate Of Dynamically Added User Controls
Apr 24, 2010I have ONE <asp:Button ID="btnAddUC" runat="server" ......./> and ONE <asp:Table ID="tblUC" runat="server"...> on my page. User clicks on btnAddUC, user control is added to the page [user can add 'n' user controls to the page]. here I have no problem, adding user controls to the page on user clicks.
My user control has ONE <asp:DropDownList ID="ddlItems" runat="server" ......./> and ONE <asp:CheckBoxList ID="chkItems" runat="server"..../>. I am exposing "ddlItems" by public method, "chkItems" is not exposed. "chkItems" is binded on SelectedIndexChanged event of "ddlItems".
Execution scenario:
User adds user control to the page, select item from the "ddlItems" ( Note: "ddlItems" is exposed by public property ) , "chkItems" is populated ( using ddlItems.SelectedItem.Value ) . User checks some checkboxes in "chkItems" and then decide to add one more user control. When the second user control is added to the page, checkboxes in the first usercontrol lose their state and apeears unchecked (NOTE: user checked some checkboxes and then added another user control).
I want to put checked beckboxes index in session ( Before another control is added, which event I should use, because at LOAD event there is nothing).
I was able to restict SelectedIndexChanged event to only that user control whcih generated it (checking _EVENTTARGET)
Forms Data Controls :: Access Dynamically Added DropDownList In GridView?
May 18, 2010I'm dynamically adding a DropDownList to the GridView in edit mode and I have set the TextBox Visibility to False. In edit mode I can see the DropDownList and I'm able to select an Item from the DropDownList but not able to access the SelectedValue in RowUpdating Event. How to get the selectedvalue of this DropDownList?
Protected Sub GridView1_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles GridView1.RowDataBound
If e.Row.RowType = DataControlRowType.DataRow And (e.Row.RowState And DataControlRowState.Edit) > 0 Then
Dim ddl as DropDownList
FillStateList(ddl)
e.Row.Cells(4).Controls.Add(ddl)
ddl is the DropDownList that is added dynamically. And the default Textbox that is in the Edit mode is set to invisible. So there are actually two controls in the same cell in edit mode(TextBox is invisible).
DirectCast(Gridview1.Rows(e.RowIndex).FindControl("ddl"),DropDownList).SelectedValue
If I use the above statement I'm getting NullException.This is Probably because its a BoundField. Is there a way I can access the DropDownList 'ddl' SelectedValue?

Web Forms :: Provide Server Side Validation For The Dynamically Added HTML Controls Using Javascript?
Mar 5, 2010I have a page with a table and two button with the names (Submit and Add Rows) When I click on Add Row a new row will be added to a page(This is achieved using javascript), when I click on submit button I will be doing server side validation. If I found any error the error will be displayed on the page. During this process the controls which were added by me were loosing its state. As a result I need to add the rows once again and need to fill the data and click on submit button. Can any one let me know how to avoid this and see that the controls donot loose their states. So that there is no need for me to create rows once again if any validation fails on the server side.
