DataGrid control properties not updating on resize event

Posted By:      Posted Date: September 28, 2010    Points: 0   Category :WPF

I have a DataGrid control on a form and I'm binding it to an ArrayList that is populated dynamically as the user scrolls.  The array list is pre-populated with blank records equal in number to the number of records in the DB.  As the user scrolls, if they stop in a place where there are blank records I populate that data from the DB.  I'm using the VisibleRowCount and VertScrollBar.Value properties to determine where I am in the DataGrid.  


The problem is that if I scroll to the bottom of the control then maximize the control it's resize event fires, the VertScrollBar is redrawn proportionally to the number of records, but the Value and VisibleRowCount remain unchanged.  If I then grab and scroll the scroll bar up then back down to the bottom, the Value and VisibleRowCount update correctly.  Is there a way for me to get these values some other way or to force the scroll bar to refresh/update manually?

Changes to Properties in the Property Window not Updating in HTML Control


I'm using VWD 2010 Express and have found that when I change a property like AutoPostBack from within the property window the corresponding tag (<asp:TextBox...>) was not updated with the property change to the tag.

Is there a setting that I can change in the VWD properties that will enable changes through the property window for a control to automatically update the HTML tag for that control?

A datagrid control that can be personalized... anyone??


Hello all,

I need a datagrid control that has following features, besides other regular stuff like paging, sorting, filtering, etc:

The user should be able to -

1. Select columns to view

2. Select column Sequence

3. Select default sort column

4. Store the setting (as a view) and use it on next visit.

5. llow multiple such views to be stored for a user for future use.

All these settings should be saved and when the user comes back he gets the same settings.

Really appreciate your time and would love to get any ideas.

Composite control: How to bubble a textbox's TextChanged event?


I've created a composite control that contains several controls, including a textbox. I'm trying to expose the TextChanged event of the textbox as an event on the composite control. I understand that events can be bubbled up the control hierarchy and handled at a higher level, which I've attempted to do, but I can't get the bubbled event to fire. When I drop the control on an aspx I can see the TextChanged event, I can subscribe to the event, but nothing ever happens. Any suggestions? Here is what I think is the relevant code:

// My event
private static readonly object EventTextChanged = new object();

//Handle the bubbled event
EventHandler textChangedHandler = (EventHandler)Events[EventTextChanged];

protected override bool OnBubbleEvent(object source, EventArgs e) 
    bool handled = false;

Knowing the event occured in user control in current page




      My web application has user control which uses third party controls called Devexpress controls. The user control is a menu  and is part of the Master page. It is placed there because this needs to be available in all the pages. My user controls raises a even on item clicked. Now, My question is that Is there any way to know that the event has occurred in page_load of the current page in which I am in?

Stored Procedures & SqlDataAdapter not updating a calendar control


Hi all,

I have a database linked to a calendar. I had a peice of code that retrieved dates from a database and populated the calendar. I wanted to tidy up my code using stored procedures (they seem neater & i assume there's a benefit somewhere). so i came up with this, however it's not working. The calendar displays, but it's not being populated with the database entries. The SqlCommand & SqlParameter I have working elsewhere in my code; as with the SqlDataAdapter (which also worked before i tried to conver to a stored procedure!) but combining these three (SqlCommand, SqlParameter & SqlDataAdapter) seem to be causing me problems.

It's probably something stupid but if someone could take a look and point me in the right direction, I'd be very grateful.


Public Sub dbConnection()
        dbConnString = ConfigurationManager.ConnectionStrings("connString").ConnectionString
        sqlConn = New SqlConnection(dbConnString)
    End Sub

Public Sub EquipmentDDLSelection()

        Dim dbCMD As New SqlCommand("PopulateCalendar", sqlConn)
        dbCMD.CommandType = CommandType.StoredProcedure

        Dim parameterBookedEvents As New SqlParameter("@bookedEvents", SqlDbType.VarChar, 50)

Personal view reverts back to default after updating properties of item


I am working with a company that has 1 site collection with several sub sites.  I have built 3 document libraries with workflow in 3 different sub sites and all behave as expected.  I have one site where ALL libraries do something perplexing;

If you are in a custom personal view and you go into the properties of a document and then exit (update or not, does not matter) it reverts back to the default view of that library. 

Has anyone seen this?  is there an option when creating an album that could cause this?

thanks in advance for any input on this odd issue.

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

Help with updating database with values from Repeater control using c#


Hello, I'm new to ASP.NET 3.5 with C#. I really need some help.

I used a Repeater control to create a simple (editable) list where, when a user logs in, they can edit their list of expenses.  The ASP page works fine.

 My issue is with the code-behind.  I am really confused with how to extract the values from the repeater control. The FindControl method does not seem to be working.  Also, the code I am using resets my 'Amount' values back to 0.00. (0.00 is the amount the user sees when they first encounter the page).

 Here's a portion of the code on the ASP page:

<asp:Repeater ID="Repeater1" runat="server" DataSourceID="SqlDataSource1"





<td><asp:Label ID="lblExpId" runat="server"  Text='<%# Bind("ExpId") %>'></asp:Label> </td>

 <td><asp:Textbox ID="lblExpense" runat="server" Width= "190px" Text='<%# Bind("ExpenseName") %>'></asp:Textbox> </td>

 <td><asp:Textbox ID="txtAmount" runat="server" Width= "100px"

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.



Parent Page

 <%@ Register Src="../../controls/contactdetail.ascx" TagName="ContactDetail" TagPrefix="tfc" %>

<tfc:ContactDetail runat="server" ID="UserControlContactDetail" Title="Contact-Detail" ContactId="1580" EnableViewState="true" />   



User Control Class

Imports System.Data
Imports System.Data.SqlClient

Partial Class control_ContactDetail

    Public Property ContactId() As Integer
            Return _ContactId
        End Get

            _ContactId = value
        End Set

Binding an event method from a control in a seperate window

How would you bind a event method from a control back to a seperate window?  I have a ActiveX control hosted in a WindowsFormsIntegration wrapper.  That is operating in its own window along with all its events.  The properties of the control are handled by a class that defines the dependency objects (thanks Bob) to provide a view model between it and a window with controls for setting/getting those properties.  Since events constrained to Window 2, is it possible to bind the events back to Window 1?
