Web Forms :: Getting Values From A Server Control Before Postback?

Aug 19, 2010

I created a ASP.Net page with dynamic controls. These controls are added by the user. In the Page_Load event a table is created with few controls.

When these dynamic controls do a postback, I can't get the values of these controls, because in my HTML code they are not available.

I only get the id of the control which triggers the postback. But I can't find it with the command FindControl. All other controls, which a are not added dynamicly are searchable.

Custom Server Controls :: Extending A Control And Losing Values On Postback?

Nov 24, 2010

I've created loads of user controls, but this is my first time dealing with extending a server control. The problem I'm getting is that the base control's data is not being persisted across postbacks in a Master/Content page.I'm actually trying to get this working using a Telerik control (for my sins), but the same issue happens with a standard Web TextBox control. Code:

[Code]....

Now, I've copied the way I handle the control state as I do it with user controls (ControlState), and it isn't working. Can someone point me in the right direction please? All the examples I find refer to creating user controls, not extending existing controls. Specifically why nothing is being persisted on post back.

Web Forms :: Restoring User Control Property Values Upon Postback?

Jun 9, 2010

I'm constructing a User Control that will have one Property called "ContractIdx". Here's how I've constructed this Property:

public int ContractIdx
{
get
{
return Convert.ToInt32(this.Attributes["ContractIdx"]);
}
set
{
this.Attributes["ContractIdx"] = value.ToString();
}
}

I'm initially loading the User Control by passing a parameter to it and setting ContractIdx accordingly. That all works fine.

Upon Postback though I'm loading the User Control without any parameters and then setting its ID property to what it was before the Postback. My understanding was that if I did this then ViewState would properly restore everything. Yet apparently this is not the case with the "ContractIdx" attribute.

Where am I mistaken in my understanding? How should I change things to get this mechanism to work?

Web Forms :: Server Control Reloading Script File On Postback?

Nov 12, 2010

I created a server control that has some javascript. Everything was working fine until I added it to a page that has localization implemented. The implementation is done within the Global. It sets the Thread.CurrentThread.CurrentCulture and CurrentUICulture based on a setting saved in session. When these values are getting set, the control throws the following error:

Microsoft JScript runtime error: Sys.InvalidOperationException: <file.js> Type has already been registered. The type may be defined multiple times or the script file that defines it may have already been loaded. A possible cause is a change of settings during a partial update.

I have the control contained within an update panel on the page, the control also contains an update panel containing all elements withing the control.

Custom Server Controls :: User Control Disappear And Reappear Some Time Later After Postback?

Jun 7, 2010

I'm getting some wierd behaviour with my User control. I've created User control & it has BUTTON which checks the validity of the number entered in the textbox of that user control. I have written Button Clik event handler in the USer Control code behind which checks the database table and tells valid or not. So far so good. In my application i dynamically add User controls. I make sure that I add them Page_Load so that for every postback UCs are visible. I'm ussing Session to save my UserControls. The problem starts at some point when i click the Validate button in the User Control all my user controls dissappear & after some postbacks all my controls appear. I don't know why this is happening. I have included my code for reference.

Web Forms :: Controls Missing Values After Postback?

Sep 23, 2010

I just uploaded an asp.net webforms site I've been working on to my ISP's servers. I have a simple page that allows users to enter schedule data. The problem is that when the user clicks the Add button and I try to process the values they've entered in the textboxes and dropdownlist in the click event handler, all the values are blank. For example, there's a DropDownList called uxStartTime on the page and after postback uxStartTime.SelectedValue is blank. However, the Response.Form[uxStartTime.UniqueID] has the proper value. I have EnableViewState="true" in the aspx page. This all works fine on my local machine, just not on the server. Can anyone tell me what's going on? I can use the Respons.Form syntax, but it's a little more verbose and prone to typos.

Forms Data Controls :: C# Set Values Of Repeater Control Values In Code Behind?

Apr 2, 2010

I have a repeater that I have bound to a sql reader via my code behind page.

However I can't figure out how to populate the controls in my repeater in my code behind code.

At the moment I am having to specify the database field e.g productprice with the control in the .aspx page like this

<asp:Label ID="LabelUnitPrice" runat="server" Text='<%# Eval("productprice") %>'></asp:Label>

I would rather specify fields in my code behind than embedding them in the .aspx page.

I also have a subtotal label control in my repeater that I would like to populate its text property by mutiplying two of the database values e.g productprice * unitprice shown in my repeater.

I need to do this in code behind, looping through the repeater. Any idea of how I can do this in C#?

Web Forms :: Passing Values From Parent Page To User Control And Maintaining The Values Added

Mar 18, 2011

I wanted to know if we can pass values from Parent page (in this case from Default.aspx page) to the user control and maintain those values on subsequent "Add/Load" of user control.

So in short, if I click the "Add" button it loads my "webusercontrol" and also I am able to pass my default.aspx dropdownlist value to this dynamically loaded user control and assign it to a "Label or Textbox" which resides in my "webusercontrol", now the problem is that the value doesn't persists! What I meant is , when I click "Add" button again the "webusercontrol" gets loaded again perfectly but now all my "Label's" in webusercontrol has the new selected value from the default.aspx dropdownlist.

So say for instance I have a Dropdownlist in Default.aspx page with Values "Apple, BlackBerry, Nokia" and initial value to be passed is "Apple", I click the "Add" button, now my "Label" inside webusercontrol has the value "Apple", perfect! Next when I click "Add" button again and select a different value to be passed this time say "BlackBerry" now I have 2 webusercontrol loaded on the page, so that means I have 2 "Labels" with different ID's, but now my first Label initially had the value "Apple" because that's what I had passed and now when I passed the value "Blackberry" both the labels of my webusercontrol has the value "BlackBerry" instead of one being "Apple" and another "BlackBerry"

Is there a way to resolve this issue? may be Dictionary List?

Web Forms :: CheckBoxList Dynamically Populated How To Retrieve Values During Postback

Apr 30, 2010

I have a form with 2 sections. The first one contains some radio buttons. The second one contains a checkboxlist. When we change the selected radio button then it modifies the elements in the checkboxlist. For this I setted the radio buttons with autopostback, and in the code behind (in OnLoad) I populate the CheckBoxList depending on the selected radio button.

This work fine.

The problem is that I also have a button at the end of my form which post the data of my form in another page (with PostBackUrl). Then in that page I would like to retrieve the values of the checked checkbox. But I can't find how to do that. In the Request.Form I don't see anything.

I searched on the web but I didn't found really a solution.

AJAX :: Passing Property Values From Server To Client In A User Control ?

Aug 13, 2010

I have a user control which has some properties configured on it. I need to access (actually, only read) the values of those properties on the client. I have done it like this.

Code behind:

[Code]....

ASPX:

[Code]....

That works but, at the back of my mind, I'm sure I've seen a neater way of doing it, although I suspect that may have been on an Extender not a User Control. Pointers on that welcome.

Also, related to that, the User Control itself has an Id which becomes part of the name of all visual objects included within it. However, the User Control is not a DOM element in its own right (because it has no visible rendering) which [I think] means that I have to attach properties to one of the visible elements within it, and not to the control itself?

Web Forms :: Dynamic Controls Creation / Rendering Based On Postback Values

Nov 8, 2010

I had successfully created a functionality where I can dynamically add rows and columns to a asp table by creating/re-creating controls on every page load.

I have 2 buttons - Add rows and Add columns that, basically according to a asp.,net page life cycle, occur in the following order and work perfectly fine.

Page load is fired and controls along with their viewstate are recreated. In Add row button click event - I just create a new table row and add controls to each cell dynamically.

Same thing with Add column, Delete Row and Delete Column button click events.

However, now I added a Dropdown which when its index is changed needs to retrieve values from the database and create controls based on those values and then also bind the Db values.

But it doesn't work correctly since the asp.net page cycle cannot capture the dropdown's selected value in page_load as the page_load fired first and then the selectedindexchanged event is fired later, the controls are not created.

I don't know how to handle this scenario and incorporate it into my existing code.
