adding ClientID to server control

Posted By:      Posted Date: September 22, 2010    Points: 0   Category :ASP.Net

hey all,

need help withthis one...

I need to add ClientID of one control to another server control attribute

this line works

<div content="<%= challengesTab_content.ClientID%>"  id="challengesTab">Challenges</div>

but when I add runat=server it doesn't get the clientid and just renders whatever is in content attribute

<div runat="server"  content="<%= challengesTab_content.ClientID%>"  id="challengesTab">Challenges</div>


so is there any way I can do it since I want to access this control on server side :s

Adding a server control on aspx page does not add events in aspx.designer.vb file



I work in VS 2008. Whenver I add a server control(Label) and set it properties in aspx.vb and build the solution, I get the error "Label1 not declared". While analyzing this issue I noticed that the event handler statements for the Label1 where not added in the designer.asp.vb file. These statement would actually be added automatically when I drag and drop a control to my webpage.

I would also like to inform the scenario after which this problem came to me. I was working in VS 2008 , VS 2005 and VS 2003 in the same machine.Could this have caused the issue ? Please advise.

Now each and everytime when I add a control, I am adding the "With Events" code in the designer page to make my build succesfull which makes me to spend more efforts.

Please advise if any settings have to be changed.



Adding Dynamic Rows in ASP.NET GridView Control with TextBoxes and with Delete functionality

In my previous examples, I have demonstrated on how to add dynamic rows in GridView control with TextBoxes and how to save the values into the database. Now, seems that most of the developers are asking if how to add a delete functionality with it. So in this example, I'm going to show on how to delete a certain row in the dynamic GridView with TextBoxes.

dynamically adding sql server columns based on number of files in fileuploader


I want to create a new table to sql database at runtime.  The column names would be "Name", "Date", "Event".  I would also like to have one more column name "Image" but the problem is that since the amount of images will vary, I want the application to count the amount of files in the Multiple fileuploader and then add a image column to the table for the respected amount of files. 

For example if i am uploading 3 files in the multiple fileuploader, the names should be "Name", "Date", "Event", "Image1", "image2", Image3"

I also would like that table name to be name dynamically from the textbox Name when the user enters the information.


I have the following code to make a new table, but I dont know how to name the fields at runtime like previously asked please help!!!

Server side validation of Fileupload control not working



I've tried this method in my code behind to try and validate that the Fileupload control has a file or not. I get the error message the the event "Server Validate" cannot be found. Can anyone tell why? Thanks.

Public Sub CustomValidator1_ServerValidate(ByVal source As Object, ByVal args As System.Web.UI.WebControls.ServerValidateEventArgs) Handles CustomValidator1.ServerValidate

' Get file name

        Dim uploadAvatar As FileUpload = DirectCast(AdvertisementForm.FindControl("uploadAvatar"), FileUpload)

        Dim UploadFileName As String = uploadAvatar.PostedFile.FileName

        If UploadFileName = "" Then
            ' There is no file selected
            args.IsValid = False
            Dim Extension As String = UploadFileName.Substring(UploadFileName.L

Adding new items to a Repeater control with transitions?



I am currently in the process of writing a facebook type 'activity feed' for a site. Currently I am binding the last 10 items to a repeater control, which contains a usercontrol representing each item. This works fine but there are a couple of requiremnts that are giving me problems and wondered if the the good people of the forum could make some suggestions.

The requirement is that when a user clicks a refresh button any new events are added to the top of the list, the previous items drop down and the equivalent number of old items drop off the bottom, all with nice slider transitions.

I have put the repeater inside of an update control and are able to handle the transitions by using RegisterStartup script to drop jquery calls onto the page for the slider. However I cannot find a way to dynamically add or remove new datarows to the repeater. I need the old items to stay in the repeater and be pushed down by the new items, so completely refreshing the datasource seems like a bad idea.

I was thinking about maybe storing the datasource in the viewstate and adding rows to that, maybe with an extra column on the end which stores what transition is needed on the databind for my jquery, but there will be a 'View more items' link at the bottom of the page, so I am worried that the list could get pretty large and there

Custom Server Control Property not maintaining state


I have created a server control consisting of a TextArea and a div under it.  My goal is to create my own asp:TextArea type control.  the div is for a Character count of the text area and seems to work ok but i added a CharacterCountVisible property to the control that is always returning true.  See Proptery definition below


<Bindable(False), Category("Appearance"), DefaultValue("True"), Localizable(True)> Property CharacterCountVisible() As Boolean
        Return _CountBoxVisible
    End Get
    Set(ByVal value As Boolean)
        _CountBoxVisible = value
    End Set
End Property

Note the _CountBoxVisible variable is define inside the class as :

Dim _CountBoxVisible as Boolean = True

What I am trying to do is give the user/coder the option to show/utilize the char count feature.  Can make it disappear with textarea1.CharacterCountVisible = False but setting it to true will not make it display.

Adding second node to SQL Server cluster fails.

I have successfully created a MSCS cluster and I have the SQL cluster up and running on the first node.   When I put the install cd in the second node and go through the install it fails with the error SQL Server Setup has encountered the following error:  Object reference not set to an instance of an object. I'm assuming I get this error because on the cluster node configuration screen the "cluster network name" box is blank.   It won't let me select a name or type a name. The SQL cluster is up and running on the first node.   I can ping the sql cluster network name from both boxes.   The setup shows the installed node and the node I"m trying to add, so I don't see any problem. I have Windows 2008 R2 on both nodes and I'm installing SQL Server 2008 R2.   Any idea how I can get past this error?    Thank you.
