I have a user control that has multiple instances on a single page.
Is it possible to have each instance use a unique ValidationGroup? I could expose a property, but I'm wondering if there's any way to do it automatically.
I am trying to assign user control from another user control ..first time its binding control successfully but when we refresh the data its giving error
saying "Object reference is not set an instance".
how to refresh data from another user control ...
My senerio below :
1 Aspx page
2. User control
calling usercontrol databinding method from aspx page but once it get refreshed ,not allowed to bind it again..
I want to make panels Visibility true or false based on a result of a Func.I have a page with controls as in the following code:

i am trying to enter a value into a texbox that is placed inside a user control called CollectionRequest. i have referenced this user control in my code behind and created an instance of it but i seem to get the above error when i try to enter some manual text. code as follows:
protected CollectionRequest collReq;
protected void Page_Load( object sender, EventArgs e )
{
collReq = (CollectionRequest)LoadControl("~/CollectionRequest.ascx");
TextBox _txt_address = (TextBox)collReq.FindControl("txt_Address");
_txt_address.Text = "thisi is an address";
control has been referenced in source file
<%@ Reference Control="~/CollectionRequest.ascx"%>
i am caling this code in my Approval.ascx.cs code. both the user controls are displayed together in the default.aspx page one above the other.
<asp:HyperLink
ID="hyper1"
runat="server"
NavigateUrl='<%#string.Format("~/PLayer.aspx?ID={0}&Type={1}",Eval("arrange_by_id"),Eval("value"))%>'><%# Eval("value")%></asp:HyperLink>
I've implemented this string format in my NavigateUrl to pass a dynamic querystring depending on the clicked item!
but you see the first part in the string format where it says "~/PLayer.aspx" i want the user control to automatically change this part according to where it's placed!

View 3 RepliesIn my ASP.Net application I have several pages that provide a list of items from the database. Currently we are using an UpdatePanel to refresh the whole list on a certain interval so that changes from other users will be propagated the screen. Obviously this isn't very efficient and we don't think it will scale well.What are some other methods for accomplishing this. Is there a specific pattern for addressing this issue?

I have designed a basic web user control to enter some values in a table. The control worked fine if it is used without similar control on same page. When another instance is pasted with different id, then both stopped working.

View 3 RepliesI don't think I understand fully how ASP.NET does inheritance of controls.I have a user control, ucBase, which has an asp.net label in the ascx file. Code behind references the label and it works fine during run time if the control is not a parent for another user parent.
If I have another user control, ucChild, inheriting from ucBase, the label in ucBase's code is always null. ucChild has no controls in its ascx fileThe server controls (like the label) needs to be declared in the ascx file and not created programmatically.What needs to be done for ucBase to see its own controls when it's a parent user control?
is there a way to add a validationgroup to a fieldset, this way i do not have to add a validationgroup attribute to every single validator within that fieldset?
View 1 RepliesI have an AJAX TabContainer. Each tab I have a ValidationSummary control with different ValidationGroup name for each tab. The problem is, now nothing show sup in the ValidationGroup when q required field is blank. The web form won't get submit but there is nothing displaying on the page either. All the RequiredFieldValidator are not showing in the web form either. All the RequiredFieldValidator controls are set to use the correct ValidationGroup too.

I have an ASP.NET TextBox ID="txtDate" in my usercontrol. It has ValidationGroup="MyUC" set. Now my UC is inside a Repeater Control. So there will be multiple instances of the same textbox. I am able to get all textboxes like: $("[id$='_txtDate']");
Each of the txtDate will have a separate ValidationGroup assigned to it, dynamically. So I want to get a textbox based on the id + ValidationGroup using jQuery / javascript.
Edited based on Josiah's Reply and the way I found:
my scenario is kind of complicated to include entire code. In short the textboxes are attached to jquery datepicker and the code below runs when a date is selected. The same handler is attached to multiple textboxes. Here is what I have:
var valgrp="MyGroup"; /*this mygroup is dynamic but keeping static for e.g.*/
var txtdate1 = $("[id$='txtDate']").filter(function(){if(this.Validators!=null){return this.Validators[0].validationGroup == valgrp;}});
var txtdate2 = $("[id$='txtDate']").filter(function(){return this.validationGroup == valgrp;});
alert("date1- " + txtdate1.val()); /*this returns date selected from datepicker*/
alert("date2 " + txtdate2.val()); /*this returns empty*/
Depending on the date I want to do something else. So txtdate1 is currently working for me where I don't have to add class to my textbox. I was playing with the txtdate2 which isn't behaving how I was expecting and so I had to post this question.
Here is a sample test to see this.validationGroup not returned:
$(function () {
$("#btntest").click(function () {
$("[id$='txtDate']").each(function () {
alert(this.validationGroup);//returns undefined
alert(this.Validators[0].validationGroup); //returns "test"
});
});
});
<input id="btntest" type="button" value="button" />
<asp:TextBox ID="txtDate" runat="server" ValidationGroup="test"></asp:TextBox>
<asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server" Text="*" ErrorMessage="Required." ControlToValidate="txtDate" ValidationGroup="test"></asp:RequiredFieldValidator>
