AJAX :: CollapsiblePanelExtender Within Custom Server Control?

Oct 1, 2010

I am trying to use a collapsible panel extender within a custom server control. I've used the extender elsewhere with no issues but when I try to add the control to my panels collection of controls in my custom control, my page crashes. Take it out and no error. I'm adding other controls to the panel...literals, labels, etc. This, however is the only ajax control I am using. Is there something I need to do as far as registering the extender with the script manager (on the master page)?

AJAX :: Use Databound Radio Buttons To Control CollapsiblePanelExtender?

Aug 17, 2010

I am using .Net 3.5 in VS 2010. I would like to use a couple of radio buttons, that are bound to data, to control the Expand/Collapse of a CollapsiblePanelExtender.

I have found several threads on the web that suggest using JavaScript to control the CollapsiblePanelExtender with a RadioButtonList, but I cannot $find the control in the JavaScript.

I have also found several threads that suggest using custom radio buttons, but I don't see how to do the databinding for these.

AJAX :: CollapsiblePanelExtender Control Always Expand And Show The Panel On The Left Margin?

Jan 6, 2011

I have made a user control using CollapsiblePanelExtender control. I am getting a small issue, that the panel that expands is not relative to the control. It always open on left side of the page. My control is in different location in different pages. How can I make sure that the expand and collapse is with respect to the control? I see "left: -36px" in the style attribute of "SettingsContentPanel". How can it be relative and doesn't break the code.

AJAX :: Developing A Custom Server Control (grid)?

Nov 24, 2010

I am interested in learning how to develop a custom asp.net ajax gridview, and I have obtained some books on the subject, but would still like a quick answer for a question: When developing a custom ajax server control, can I somehow use jquery for the client-side part of the control? Are there any collisions with ASP.NET AJAX framework and are there special requirements (e.g. only available for .NET 4.0 etc.)?I would also appreciate any suggestions on resources from which I can learn more about developing a custom asp.net ajax server control from scratch.

Custom Server Controls :: Custom Control's Constructor / User To Set That variable In The Properties Window After They Drag The Control Onto A Form?

Mar 4, 2010

I have a custom control which inherit from the Table class and in the constructor, it takes a an integer as an argument. There is no empty constructor.

Is there a way for the user to set that variable in the properties window after they drag the control onto a form.

I know some .NET controls, you can set the source for the parameter to different things like another control's property, QueryString using just the properties window.

Right now, I have to create the control dynamically. I read the query string and then created the object.

Custom Server Controls :: Paging And Sorting Gridview Custom Control Inside Of A Wizard Control?

Dec 24, 2010

here's a situation and I would appreciate your response.

I have programmatically created the Wizard control:

Page_Load(obj s, evargs e)
{
Wizard ClaimDetailWizard = new Wizard();
foreach(int item in selectedItems)
{
//create new step
//added custom control to new step
//add step to wizard
}
//added wizard to a placeholder on a page
}

Based on List I get from Session i added new steps to my wizard To each step I had added a custom control

Each custom control in tern contains another custom Gridview Control in it.

So here's the problem when the page loads for example for two steps. All is good Wizard does what it's supposed to do.

But when I try to use sorting or paging in that custom Gridview. Somehow it displays the gridview I should see in the next step of the wizard.

Also what I'm noticing through debugging. Is that when I press next in the wizard I go back to the original page where I do all of the code specified above, and it recreates the wizzard. But it goes to the next step. Is this the way wizard supposed to work? Just doesn't seem very efficient.

Custom Server Controls :: Add This Control To The Page,an Alert To Check The Text Value Of The Custom Control?

Dec 20, 2010

created a Custom Textbox Control that is intended to be a "masked date" textbox, so that I can handle different ways a user might enter in a date and make it work no matter what.I did this by creating a custom control with 3 separate Textboxes one for month,one for day one for year,then do some handling for different things that could be entered and it would all work.

The problem I am having is,when I add this control to the page,if I do an alert to check the Text value of the custom control it just gives me "[ServerControl1]" even if I enter in a date.

I tried doing an AutoPostback after entering so that it would refesh the Viewstate to have the values of the textboxes but the control doesnt seem to actually postback, even though I have it enabled.accessing the Textbox value after someoen
has entered a date?first custom control I have created and have been using google.

My Server Control Code is as follows:

I am creating a custom server control, and I am wanting to include a JavaScript file in the dll file when the control is built. I have tried suggestions from the following websites:[URL] But after following the directions, If I use firebug to see what errors show up, the JavaScript functions that are being called all say "goNext is not defined" which leads me to believe the JavaScript file is not being added correctly.

Some information on what my control looks like

In my AssemblyInfo I have the following:

Custom Server Controls :: Custom Server Control From Datalist Not Binding?

Feb 24, 2010

I have a control inherited from datalist because I want all the same functionality but with a couple of extra properties.

I have a method that goes off and gets the data inside the control (instead of using a separate datasource ID). It's reading it from XML into a datatable.

If on the code behind of the aspx page I put the control on I put a thecontrol.databind() in the page load, all works well.

However I'd rather not have to do this, instead the control should bind itself.

I gather it's something to do with the order of events but I'm not sure what to do about it.

I don't want to reinvent the datalist wheel, just add a couple of properties and get it's own data

Sample code (some code removed for clarity)

Custom Server Controls :: Custom Server Control - Not Found In .cs File?

May 27, 2010

I'm having a dumb problem that is killing me. I have created the simpelest custom server control in VS 2008 c# called MyMsgBox. On the ASP page I put it in and register it. But, in the .cs file, when I try to call one of its functions I get the compile error that it is not found. The funny thing is that intellesense has it in the list and all of the functions with their given arguements. At the top of the .cs file I am using the namespace. The code for the custom server control is in the App_Code folder.
Also when I remove all refrences to its functions, the code compiles and when debugging the constructor for the class MyMsgBox gets hit.

<%@ Register TagPrefix="cc1" Namespace="CustomServerControls" %>
...
<cc1:MyMsgBox ID="msgBox1" runat="server" />
Task.aspx.cs
...
Using CustomServerControls;
...

this.msgBox1.confirm("Would You Like to add a new Task for this PO/Contract? ", "hid_f"); Error Message: 'Tasks' does not contain a definition for 'msgBox1' and no extension method 'msgBox1' accepting a first argument of type 'Tasks' could be found (are you missing a using directive or an assembly reference?)
