Hi All,

I created a .NET user control to work as a DropdownCheckbox and added Jquery to give the sliding and hide effects. The code is as below:

 <script language="javascript" type="text/javascript">
        var showRegionWindow = function (ev) {
            var pos = $("#lnkChangeRegion").offset();
            var width = 230;
            var height = 55;
            //$("#changeRegionPanel").css({ "left": +((pos.left) - 215) + "px", "top": height + 16 + "px" });.
            document.getElementById("lnkChangeRegion").style.display = 'none';

        var hideRegionWindow = function (ev) {
            var textVal = "";

User Control not accessing the value of the properties send to it from the aspx page.


I have a dynamic accordion on a page. Set its datasource to an object of paged data source.The user control is in the accordions content template. When i was writing code the properties were showing but after giving the values of databases as


<uc:UserControl1  runat="server" Property1='<%#DataBinder.Eval(Container.DataItem,"columname1")%>' Property2='<%#DataBinder.Eval(Container.DataItem,"columname2")%>'  ></uc:UserControl1>


but the values shows null, these properties are shown as textboxes text property by user control.

MoreOver when I checked the values of database Items.So i made a textbox instead of usercontrol here as

<asp:TextBox ID="txtTest" runat="server" Text='<%#DataBinder.Eval(Container.DataItem,"Columname1")%>'></asp:TextBox>

It is showing the correct value. And if i pass the value directly it is also showing correctly like

<uc:UserControl1  runat="server" Property1="XYZ")%>' Property2="ABC")%>'  ></uc:UserControl1>

. where I am wrong

the problem is eval is not passing the value to usercont

Problem with User Control Properties


I've been trying to figure out a problem that I've had for the past week and believe that the issue is something with a user control that I created. In short, the properties for the user control are recognized by intelisense when I register the control and then add it in the markup for a page. However, the values that I set in the markup are ignored by the class as if the properties don't exist.

User control or sub-form inside tab-pages? Best practice?

I've got a Windows Forms application with numerous tab-pages within a tab-control. Each tab-page is a diffirent user entry form with different controls of varying types. As the application is fairly large it is important that more than one developer can work on it simultaneously. Thus we decided to create a form for each tab so that different developers could work on different forms at the same time without overwriting each other's code. Each of these "sub-forms" are then assigned its relevant container tab-page as its parent. This works well but I was wondering if this is good practice or not, after another colleague commented that we are making forms look like user controls and that we should rather be creating a user control for each tab. I've converted two of the forms to user controls with relative ease and it does work nicely as well but with one draw back. On the main parent form, e.g. frmMain, where the tab control lives, there is one single button the clear the current display. When you click "Clear display" it clears various others items displayed on the main from, finds the current selected tab and clears its contents. The latter is easy to do with sub forms as I can simply close and dispose the sub form inside the selected tab, and load a new instance. I don't have to write custom logic to go and reset/clear each control on that form. Thi

How to create a window a user can move around inside of a flow panel?

Problem binding business objects to custom user control properties

I have created a user control (supplierPicker) intended to allows a supplier database to be searched and a supplier selected. I want to be able to use this control in a number of other user controls, by binding the suppplierID property of the supplierPicker to a supplierID property in a business object, which is set as the datacontext of the parent user control. When I do this, and there is a supplierID specified in the business ofbject, the binding sets the supplierID in the supplierPicker control and it shows the correct supplier name in the textbox. However when the supplierID DependencyProperty is changed from within the supplierPicker the newly selected supplier name is shown in the TextBox, but the SupplierID does not propogate back to the business object. Other controls on the parent form work fine, so the binding to the business object seems to be ok. Any pointers as to what I'm doing wrong here would be grately appreciated.  This one has been driving me nuts for days! Snipped code for the supplier picker:         public partial class SupplierPicker : UserControl, INotifyPropertyChanged     {         public static DependencyProperty SupplierIDProperty;         public event PropertyChangedEventHandler PropertyChan

page inside update panel doesn't refresh the session object after postback of any control



I have many controls like dropdown, radiobuttonlist, etc on my page and I put all these controls inside the update panel so that the page doesn't look to be posting back when something is selected. Now the working on the page is very smooth. But the session object isn't getting refreshed even if I postback to the server and as a result even if the users are working on the page they are being sent to the login screen after 20 mins.

Is there anyway where I could put all the controls in update panel and still refresh the session after any postback(dropdown selection)

Any help is greatly appreciated.

Thanks in advance
