Web Forms :: Set SelectedValue Of DDL In UserControl From Page
Mar 31, 2010
What is the proper way to set the selectedvalue of a DDL inside a web user control? My current structure is PAGE > USERCONTROL [FORMVIEW] > USERCONTROL [DROPDOWNLIST]Inside my FORMVIEW user control, I am setting the value of my DROPDOWNLIST user control through an exposed property located within the DROPDOWNLIST user control, called SelectedLocation. However when I changeMode of the FORMVIEW control, depending on where I call my method to bind myROPDOWNLIST, it will either bind it twice or won't bind it all.

I have a page for webparts and have a usercontrol in the declarativecatalog. The user control had a gridview. I need to click (select) an item (row) in the gridview and change the selected value of the DDL in the parent (I guess this is the appropriate term) page.
<%@ Page Language="VB" MasterPageFile="~/MyStuff/MyStuff.master" AutoEventWireup="false" CodeFile="Default.aspx.vb" Inherits="MyStuff_Default" title="MyStuff" %>

Using VB.Net/Asp.Net 2008, web app with Master page.I have a content page where all of the content is wrapped in an UpdatePanel that uses a UserControl called GetEmployee.ascx that I created.
In the user control I have a listbox filled with employeeIDs for the DataValueField, in fact for testing to make sure I'm getting the ID I temporarily set the DataTextField to employeeID also. Anyways I keep getting "" error saying I have not selected anything even when I do so I put a breakpoint and set a watch to find out selectedIndex, value and item and nothing.
after the user selects an employee they should click on the "select employee" button so I have some code there to find out which employee was selected. I have events setup in the GetEmployee.ascx user control to get the value selected:
[Code]....
and I have a breakpoint and it hits the "selectedIndexChanged" event first so I put a watch there and see the following.
<WatchValues>
SelectedIndex = -1
SelectedItem = Nothing
SelectedValue = ""
</WatchValues>
why am I not seeing the selected value?

It is working fine in InsertItemTemplate, but in EditItemTemplate i am getting this error "'branchDDL' has a SelectedValue which is invalid because it does not exist in the list of items. Parameter name: value".
. Following is the code:
<asp:TemplateField
HeaderText="Course"

I have officially wasted about two days trying to figure out what the heck was going on with my asp.net page. I actually thought it was an issue with my updatepanel code, but after reading another post I was able to reproduce the same results. [URL]
I just manually added the following control to the page (no code behind for the listbox) and it is nested in an ajax tabcontrainer inside an updatepanel. If you set item 20 as selected the page flickers when loading that tab. I tried the css mentioned (style="overflow:hidden") on the tabcontainer,tab panel, update panel and dropdownlist, but no luck. Crazy select item 19 no flicker, 20 (which is actually the 21st item) and it does flicker. This is driving me insane. And yes this only occurs in FireFox ( running 3.6).

We were having occasional reports where the value of a set of DropDownBoxs in a GridView would be reset to the first value item in the list.
We finally tracked it down to a timing issue where a user would click Save before the page finished rendering/loading the data, and we are able to repro it on the production server but not locally because the page loads too quickly.
How would we go about detecting this on the server side to know the data returned is invalid or otherwise stop from setting data that the user didn't set?

im creating site with usercontrols. I have repeater, inside it is another repeater with usercontrol. My problem is passing BindedValue to usercontrol.Bindings works fine and binds the value i need but it cannot pass the value to usercontrol. When i type it manually it works, when i bind it, it passes null (!).I've tried get,set, functions (ondatabound, onload, oninit), accessing control from code with no luck. Ive read and tried to do all the google solutions but with no luck. (even with creating usercontrol inheritance)

There are 2 UserControls UC1 and UC2, and there is one more class C. I want to share the same instance of c in both UserControls. I know that this can be possible with properties in both UC's and by registering UC2 in UC1 or vice versa. But I want the solution to be loosely coupled. Any best possible way without touching the Actual Page (which hosts UC's)? So i need some best possible way between UCs transfering C.

I am developing a usercontrol, in this case a toolbar. Some of the buttons on the toolbar will interact with other objects on the page which are not part of the toolbar. (In this case a map) So the toolbar code behind wants to say something like this:
[code]....
My problem is that MyMap does not exist in the design environment of the usercontrol and therefore produces an error when it is referenced. So my question is, How is this typically handled? Can the usercontrol reference another control that does not exist within itself?

i have user controls inherits from base user control like this:
[Code]....
How do i insert CustomerSendMail & UserSendMail into aspx page?
Note: The derived user controls having the same control layout as the base user control. Making copies of ascx page for CustomerSendMail & UserSendMail is not good idea, because if i modify the base's ascx page, the old CustomerSendMail & UserSendMail 's ascx page should be replace with the new one.

I have a WebForms page that has two DropDownList controls on it that both contain a range of temperatures from 60-80 degrees, one for heating the other for cooling. They are declared in the .aspx as:
<asp:DropDownList ID="heating" runat="server" />
<asp:DropDownList ID="cooling" runat="server" />
The values for each list are populated in the code-behind using:
for(int i = 60; i <= 80; i++)
{
var listItem = new ListItem(i + " degrees", i.ToString());
heating.Items.Add(listItem);
cooling.Items.Add(listItem);
}
When I try to set the selected value for each DropDownList using the values in an object containing data loaded from the database using:heating.SelectedValue = myHome.avgHeatingTemp.ToString();
cooling.SelectedValue = myHome.avgCoolingTemp.ToString();
The SelectedValue for both lists is set first to the value in myHome.avgHeatingTemp, then to the value in myHome.avgCoolingTemp. Heres what the values are for each variable after each step of the process of setting the SelectedValues:
Initial State
heating.SelectedValue: 60
cooling.SelectedValue: 60 [code]....

I have a UserControl I created for Navigation that is added to a master page. In a host page, I have a drop down list that I would like to change the value of a dropdownlist in the user control when changed.
I've tried to use the findControl to get the Hyperlink control I'd like to change the value of, but it's always returning nothing. I am thinking this is because the control is nested in a master page. how I can change the value of this item based on the value of a dropdownlist in the aspx page?

I have a requirement to hide certain buttons in a standard MOSS page. The buttons are generated by a Microsoft UserControl and some buttons must be hidden before displayed to the user. This page cannot be customized, so the only approach is to have an httpmodule which would use some Javascript and C# to hide the unwanted buttons. So my question is during which event should the javascript be used to pick out the DOM elements and set their visible property? Can anyone give a code example?

I have a problem with calling a method on a aspx page from a usercontrol.
The case is: I have 1 main page with 5 usercontrols, when something goes wrong in the code I want to display the error message in a Modalpopup Extender. I can create for each usercontrol a different modalpopup extender but isn't much easier when I make 1 popup in the aspx page. But the problem is: How should I call a method in the aspx page that open the popup?
I have search several hours on the internet but can't find anything useful.
