Usercontrols - Server-side Value Being Assigned In This Custom Control?

Jul 15, 2010

I am looking at somebody else's code and in it there is a user control:

<UserControl:Comments ID="Comments1" runat="server" ObjectID="4" ObjectRecordID='<%#((Alert)Container.DataItem).AlertId %>'></UserControl:Comments>

What I don't quite understand is how the value for ObjectRecordID gets assigned. I
understand by looking at the code that AlerId is getting assigned to ObjectRecordID
but how is ((Alert)Container.DataItem).AlertId grabbing its value?

Custom Server Controls :: Custom Validator Client-side Validation Cannot Work?

Jan 13, 2010

I've been trying to get a custom validator component working that ensures at least one checkbox from a checkboxlist has been checked. I've been used some code I found on dotnetjunkies.com but the client-side validation didn't work. I've been attempting to modify it to get the client-side javascript validation to work with no luck. Basically, I compile the below code into a DLL and add it to my bin folder.

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.

Server Side Control Hidden - Possible To Read Values Client Side

Jan 30, 2010

I've got two textboxes running server side and have their visibility turned off. I'm using a couple of ASP.NET controls which require the textboxes to exist. However, I am filling them from the code behind and would not like the user to see this. Can the user turn the visibility on and see the values entered in the text box? I tried using FireBug, and I couldn't seem to select the visibility option in order to edit it. However, I'm quite new to Firebug, so there may be another way? Or does running it server side mean that the client can't ever view the contents of the textbox?

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:

How To Get Same Validators Control To Both Client Side And Server Side

May 20, 2010

For the ASP.NET validator controls, I want to use both client-side validation for the user experience and server-side validation to guard against hackers. ASP.NET documentation leads me to believe that if EnableClientScript="True" then there will be no server-side validation if client-side validation is possible for the user agent. To get server-side validation, the documentation says use EnableClientScript="False", which bypasses client-side validation altogether.

Am I misunderstanding how the validator controls work? I ask because it seems obvious that many developers would want both client and server side validation together, and I find it hard to believe both together is not possible with one of the standard validation controls.

If I am understanding the ASP.NET documentation correctly, then I can find only two options:

Use two validator controls exactly the same except for their ID and EnableClientScript properties. Obviously ugly for maintaining two controls almost the same.Write some code behind to check if postback then invoke the Validate method on the validator group. Why write code behind if there a way to be automatic from the control?

Is there a way to do so using a single validator control with no code behind?
