UpdatePanel Dynamically Loaded Web UserControl Will Disappear After Clicking Any Button Inside The UserControl?
Mar 17, 2011I've a ASP.Net page (Default.aspx) which will load UserControl (ucontrol.ascx) dynamically into an UpdatePanel. By using UpdatePanel, we believe we're able to prevent the entire page to be posted-back.
My problem is, within the UserControl, we have some form controls, such as inputs and buttons; after the UserControl is loaded, clicking on any button inside the UserControl will cause the UpdatePanel to be blanked. During the investigation, I found that, breakpoints within the Button1_Click() in the code-behind for the UserControl is never reached. Please reference to the code below, this references to [REFERENCE]1.

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?
Forms Data Controls :: Setting Height Of Linkbuttuon Which Will Added Dynamically?
Jun 18, 2010[Code]....
I am adding linkbutton dynamically (actually above snippet tells what I am actually doing, in reality TableRow and TableCell are added dynamiccally). My problem is, I am not setting height of linkbuttuon which will added dynamically. I have no idea what text I have to add to linkbutton.
What I want, after all the link buttons are added, iterate through each added lin button, get the height of each linkbutton, store the max height, then re-iterate throgh the link buttons and set the height of each link button to max height.
Web Forms :: Passing Values From Parent Page To User Control And Maintaining The Values Added
Mar 18, 2011I wanted to know if we can pass values from Parent page (in this case from Default.aspx page) to the user control and maintain those values on subsequent "Add/Load" of user control.
So in short, if I click the "Add" button it loads my "webusercontrol" and also I am able to pass my default.aspx dropdownlist value to this dynamically loaded user control and assign it to a "Label or Textbox" which resides in my "webusercontrol", now the problem is that the value doesn't persists! What I meant is , when I click "Add" button again the "webusercontrol" gets loaded again perfectly but now all my "Label's" in webusercontrol has the new selected value from the default.aspx dropdownlist.
So say for instance I have a Dropdownlist in Default.aspx page with Values "Apple, BlackBerry, Nokia" and initial value to be passed is "Apple", I click the "Add" button, now my "Label" inside webusercontrol has the value "Apple", perfect! Next when I click "Add" button again and select a different value to be passed this time say "BlackBerry" now I have 2 webusercontrol loaded on the page, so that means I have 2 "Labels" with different ID's, but now my first Label initially had the value "Apple" because that's what I had passed and now when I passed the value "Blackberry" both the labels of my webusercontrol has the value "BlackBerry" instead of one being "Apple" and another "BlackBerry"
Is there a way to resolve this issue? may be Dictionary List?
C# - Passing In A Value To A Usercontrol Through A Foreach Loop?
Dec 21, 2010in my asp.net mark up I have a foreach loop that iterates through a simple list. In this foreach loop I am adding a new user control and attempting to pass in the value from the loop. However, this value just wont budge and get inside that damn control!
<%foreach (userInfo i in this.items)
{ %>
<uc1:ItemControl ID="ItemControl" runat="server" UserID='<%#Eval("userID") %>'/>
<%} %>
userID is a public property in the control, when it goes to set, the value is just literally :
<%#Eval("userID") %>. I've tried #Bind and =Value but nothing seems to work.
