Web Forms :: Usercontrol Constructor Parameter - Unable To Pass The Value To Usercontrol?
Apr 6, 2010im 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)
View 5 RepliesC# - How To Pass A Type To UserControl
Feb 19, 2010I have a UserControl (lets say Foo.ascx) that has a Type public property with the name Bar. I am looking for a way that when i declare this usercontrol in the source view of the markup part to pass a type. for example
<%@ Register Src="~/Controls/Foo.ascx" TagPrefix="prfx" TagName="fooCtrl" %>
and then use it as
<prfx:fooCtrl ID="theId" runat="server" />
if for example i wanted to pass to the control the type of string (such as typeof(string))
something that would have this effect
<prfx:fooCtrl ID="theId" runat="server" Bar="typeof(string)" />
how can it be done? Before anyone asks, the reason is that i have many other properties in this usercontrol that i pass in this manner and i want to avoid using the CodeBehind just to pass the Type
What Are The Available Ways To Pass A Parameter To A UserControl
Jan 29, 2011What are the available ways to pass a parameter to a UserControl ?I know the session option but actually I don't prefer it because it'll retain when any exception is occurred. I mean I prefer something like the QueryString (rely on the call or request).Note: My UserControl will be shown throught a modal popup using JQuery.

Custom Server Controls :: Can't Pass Data From Usercontrol To Page
Jan 25, 2011I tried both, loading the usercontrol when needed and I also tried adding it directly into the aspx.
Nothing worked. With the second one (what's meant to be the easiest option) I tried with delegates and events (but can't access de usercontrol event from page) and tried with properties (I can access properties but they're always empty)
Pass Values From MasterPage UserControl To Child ASPX Page?
May 4, 2010Senario: Masterpage with a UserControl and a child ASPX page
In the past when using this senario I've used an Interface as a way to pass a value from the UserControl (embedded in a master page) to the masterpage code behind then consume that value in the child aspx page.
My question is now that asp.net 4 have arrived is this still a good way to achieve this or is there another or perhaps better way to do it? I've read somewhere that perhaps "delegates" is perhaps another route to take.
User Controls :: How To Pass Value From UserControl (ASCX) To Page (ASPX)
Jan 19, 2014I have two files in my project. One is user control (popup) customerpicker.ascx and one is default.aspx page. In customerpicker I have dynamically generated gridview and 'select' column with SelectButton.
What I want is this: When I click on 'select' on random row in gridview, then I like to display value from selected row immediately (like ajax) to aspx.page. How it is possible?
There is part of my code in .ascx:
public string showOnaspx { get; set; }
protected void GridView1_SelectedIndexChanging(object sender, GridViewSelectEventArgs e)
{
GridViewRow row = GridView1.Rows[e.NewSelectedIndex];
showOnaspx = row.Cells[1].Text;
e.Cancel = true;
}
protected void GridView1_SelectedIndexChanged(object sender, EventArgs e)
{
GridViewRow row = GridView1.SelectedRow;
//row[i].Attributes.Add("onclick", "$('#ContentIndex_sometextbox).val(" + row[i].Cells[1].Text// + "); $('#Close').click();");
}
I also tried with jqeury (comment in selectedindexchanged function), but it does not work well, because user have to click SELECT two times to effect.

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.

AJAX :: Nested UserControl With UserControl Disappears On Partial Postback
Jan 28, 2011I have a page with an UpdatePanel with a UserControl in it. That UserControl contains a GridView with a nested UserControl that seems to disappear when the parent UserControl is rebound. I cannot for the life of me figure out why the child UserControl disappears. The code works beautifully on the first load, but any partial postback causes the "Pick" UserControl to disappear.

Web Forms :: UserControl To UserControl - Same Object Instance Transfer
Sep 27, 2010There 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.

How To Configure To Pass The ID Pass From The ASP To The WCF
Mar 12, 2010I have a ASP.NET MVC page, which call WCF logic.
The system is single-signon using NTML. Both the ASP page and the WCF will use the UserIdentity to get user login information.
Other then NTML, I will also have a Form based authorization (with AD) in same system.
The ASP page, is it simple and I can have it from HttpContext.Current.Request.LogonUserIdentity.
However, it seem it is missing from the WCF which call by the ASP, not from browser.
How to configure to pass the ID pass from the ASP to the WCF?
