Using DataRepeater Control On A Web Page
Apr 12, 2011Is the "DataRepeater" control derived from the "Visual Basic Power Packs" applicable on ASP.NET web forms? If not, is there a similar control for use on the ASP.NET web pages?

Getting Value Of A Control On Datarepeater
Jan 17, 2011Is it possible to get value of a text box, say at row 4 of a datarepeater. I did it by moving control to it, but that does not work the way I want. I used code DataRepeater1.currentIndex=5, and then picked the value. Is there any possibility of getting the value without moving control to this row. I mean the way we get value from datagridview (vrName=datagridview1.item(1,1).value)

Forms :: Using CheckBox As Control In DataRepeater Object
Aug 31, 2011I have a checkbox as a control in a datarepeater object. I have an event handler function which handles the checkchanged event for this checkbox and sets the visibility of other fields based on it. However, the problem I am having is that the event handler function is getting fired when I set the datasource for the datarepeater - hence when the data is being populated. So the event handler function ends up trying to set the visibility of a field that has not been created yet and bombs out with a NullReferenceException error. Is there a way to stop this event handler being fired when the datarepeater is being populated? I only want this function to be called if that checkbox is changed by the user after the form has loaded.
View 2 RepliesUse A Checkbox To Add Data To Its Own Item In Datarepeater Control?
Sep 21, 2009I am using the Datarepeater control to make a report. I am including the a couple of bound labels and a checkbox in the Datarepeater item template. When I run the report and multiple items come up, I'd like to use the checkbox and clear the items by resetting there values to NOTHING. When I check the checkbox for the item, how do I code it so row.text=nothing only applies to the row that the checkbox is on?
View 1 RepliesVirtual Mode In DataRepeater Control / How To Update Data Changes
Feb 25, 2011How do i make sure that the changes "done" by a user interacting with a DataRepeater control are reflected in the corresponding database source table? I have used DataRepeater in VirtualMode, do I have to supply my own code that will "actually" make corresponding changes to the actual tables, or is there a way of "configuring" or "binding" the controls on the DataRepeater to the "dataSet" so that the changes made by the user are reflected automatically in the underlying table? Whatever I have tried so far has yielded no results; whenever i edit the data on the control, the actual data is not updated. I attach a file showing the only events under which i have put some code: Load event of the Windows form, and the ItemValueNeeded event of the Repeater Control.
View 4 RepliesVS 2008 Bound DataRepeater With Unbound CheckBox Control?
Mar 28, 2011I'm seriously about to abandon this DataRepeater. I don't want to. I want greater design control than the DataGridView. I've played with various Events for days and have settled on the CheckBox.CheckChanged Event.
What I'm trying to accomplish: My Bound DataRepeater has an UnBound CheckBox in each DataRepeaterItem.When the user 'Checks' the CheckBox, I want to change the value of a NumericUpDown Control to the value of a hidden, Bound Label.
[Code]...
This causes other, seemingly random, DataRepeaterItems (Rows) to also become Checked and thus it's NumericUpDown value to change.Am I going about this from the wrong angle? Can't see the forest for the trees?
Form With A Tab Control That Has 18 Pages - Click On A Tab It Opens The Page And Select A Textbox On That Page
Mar 8, 2009I have a form with a Tab Control that has 18 pages. When I click on a tab it opens the page and select a textbox on that page (txtTextbox1. Select() ). This works for the first 8 pages but not for the remaining 10 pages. Although on these pages I can mouse click on the textbox, enter info, save then click my Add button that clears the textboxes and has the code (txtTextbox1. Select() ). The textbox is selected just fine. The code for all my pages is the same except for the tab name and the control names. The tab key will move the selection to the next textbox in order on all pages and the Enter key is coded to do the same. The first 8 pages have a total of 256 labels, buttons, list boxes, textboxes and checkboxes on them.

View 1 RepliesAccess A Page Variable From User Control Placed On That Page From VB?
Dec 27, 2009I want to access a page variable from a user control placed on that page. All the solutions work in C# via casting to the page class. The problem is that this doesn't work in VB. The page class is not selectable from the Intellisense dialog. Manual typing results in the error type not defined. It is strange that C# can do this without a problem. What is the proper solution for this in VB? I had other cases where I needed to access a control on the main page. C# again uses a cast to the page class to access the control. This doesn't work in VB again. So how can I access the page class from a user control in generell?

Scroll An ASP.NET Page Under Control Of The Code-behind Page?
Jun 3, 2009I have an ASP.NET 3.5 page with some AJAX, some Validators and some business-rule validation done in the code-behind page (VB.NET).
The Validators set focus to the 'offending' control when an error is detected.
When a business rule is violated, I used the following code to generate some javascript "on the fly" and execute it to simulate the Winforms "MessageBox.Show" functionality:
Sub DisplayMessages()
Dim lblError As New Label
lblError.Text = "<script language='javascript'>" & Environment.NewLine & "window.alert('"
[Code]....
At the end of the "btnSave.Click" code, if everything went ok, calling that subroutine.
What I get is the page scrolling to the top and then back to where it was when the Save button was clicked.
For various reasons, 'MaintainScrollPositionOnPostback="True"' is in the Page directives at the top of the .aspx code. What I'd really like is to make that FALSE for just a moment so that the page resets at the top - again, only if everything is ok and only for this button (there are other buttons on the page that require the page to keep it's scroll position).
Asp.net - Adding To Page Control Collection From Inside A User Control?
Feb 12, 2011I have an asp.net usercontrol which represents a "popup" dialog. Basically, it's a wrapper for the jQuery UI dialog which can be subclassed to easily make dialogs. As part of this control, I need to inject a div into the page the control is used on, either at the very top or very bottom of the form so that when the popup is instantiated, it's parent is changed to this div. This allows "nested" popups without the child popup being trapped inside the parent popup.
The trouble is, I can't find a safe way to inject this div into the page. A usercontrol doesn't have a preinit event, so I can't do it there, and calling Page.Form.Controls.Add(...) in Init, Load or PreRender causes the standard exception "The control collection cannot be modified during DataBind, Init, Load, PreRender or Unload phases."
I thought I had found a solution by using. ScriptManager.RegisterClientScriptBlock(Page, Me.GetType, UniqueID + "_Dialog_Div", containerDiv, False) which seemed to work well normally, but recently a coworker tried putting an UpdatePanel inside the dialog and now she's getting the error "The script tag registered for type 'ASP.controls_order_viewzips_ascx' and key 'ctl00$ContentBody$OViewZips_Dialog_Div' has invalid characters outside of the script tags: . Only properly formatted script tags can be registered."
How are you supposed to add controls to the pages control collection from inside a user control?

The label's properties are working correctly, but the image does not show. Is this not the correct way to have an image on the DataRepeater control? There is no code for this since it was just a drag-n-drop.
