I'm trying to enable/disable controls inside a repeater:
<asp:Repeater ID="Repeater1" OnItemCommand="RepeaterItemCommand" runat="server">
<HeaderTemplate>
<table>
<th>
[code]....
i have this function to enable disable the controls on a form....
Private Sub EnableDisableAll(ByVal xType As Boolean)
Dim ctl As Control
For Each ctl In Me.Controls
If TypeOf ctl Is TextBox Then
ctl.Enabled = xType
[Code]...
everything fine ...but when the controls r disabled it shows in the dull color. can i change the color ? as u can see i have given the command to change the forcolor to red to textbox but it still shows in dull greay... i dont want it to be enabled as i am using this to just give a view of records....the back color is changing to white but not the forecolor.....is there any thing more to be done...or any better way so as the items remain enabled but i dont allow the changes to be done.
I'm working on a winform which contains several controls like textboxes, radio buttons, datagridviews... All of these controls have been added to a main group box called gbDataEntry. My problem is when the user is seeing the form, I set gbDataEntry.Enabled = False but I want to enable some controls like DataGridviews so the user can scroll them. After disabling gbDataGridview I set DataGridView1.Enabled = True but it seems that the datagridview does not respond to this line. Why?

View 8 RepliesI am enrolled in a class in Visual Basic 2008. I wanted to drop the class, but it is too late. Now, I am stuck with this project that the professor assigned and it's due this Thursday. Anyway, how do I do this: The credit card number TextBox control is dynamically enabled/disabled depending on the choice of payment type? And did I do the newOrderButton correctly (see code below)? This is also the clear button. And is there a way to do a reset Form? Sorry for that many questions. I am really lost right now because there is a lot to do in this project and I don't even have a clue of how I am going to finish this project.

View 4 Replieswhen I got home to try out the method in the above post in my real application things did not work out.The big difference is that my main form is a MDI. When I open my edit form, it's mdiparent is set to the main form. When I click 'edit' and then disable "me" the entire application goes modal.I was expecting only the MDI child to go disabled, not the whole application..Basically, I want only the MDI child window that opens it's "edit" dialog to go disabled..
View 1 RepliesHere lies my form: Attachment 72542 I have to perform save and show operations with the access database. If i select the Bank Account radiobutton(Radiobutton1) then Bank Account No. combobox is enabled,Credit Card No. combobox is disabled and user can input the value only in the Bank Account No. field. When the form loads then both the combobox1 and combobox2 are disabled and as the user selects the radiobutton the combobox are enabled accordingly. So i did the following code in the form load event:

MessageBox.Show("Disabled")
Button1.Enabled = False
Button2.Enabled = True

View 6 RepliesI am developing an application with a DataGridView (dgvData) that requires a ToolStipMenuItem (tsmiSelectNetwork) of a ContextMenuStrip (cmsNetwork) to be enabled and disabled programmatically based on if the column is sorted or not.
I have set:
'tsmiSelectNetwork.Enabled = False' at runtime
'tsmiSelectNetwork.Text = Select All' at runtime
'dgvData.Columns(5).ContextMenuStrip = cmsNetwork' programmatically
When dgvData is sorted by column 5, tsmiSelectNetwork.Enabled should be set to True; when it is sorted by any other column, it should be set to False (see code below)

The debug output indicates it is functioning properly, but what you seen on the screen is not.

I have successfully ported a VB6 application to VB.NET (VS2008, .NET 2.0). Much optimization and rewriting has been done, but there is one possible BUG i cannot overcome. I have a standard HSCROLLBAR control used for accepting a numeric input. The control needs to be disabled during complex computational routines to prevent additional user input. I am setting the enabled property to false and reenabling the control at the end of the calculation cycle. The control is enabled and disabled a few times, because some code has been placed in the onpaint event of a drawing area, and separating the calculation part from the drawing part will be a huge task.
Large changes are handled correctly. Small changes aren't. The problem is that the control freezes in a unknown state after clicking on the arrows. A second click makes the control (and its parent control box) jump up and over everything else in their container.The scrollbar remains functional only via the contextual menu. This happens both in debug and release builds. There are no overrides. Coding/Test platform XP SP3 (more than 1 machine).
There is no code whatsoever that handles neither the parent control nor the scrollbar repositioning and resizing. The only code takes the value of the scrollbar and passes to the calculation section. If I omit disabling and reenabling the control, everything works fine.i tried rebuilding the control from scratch. forcing enabling the control after it has gone haywire does not make changes, disabling the groupbox instead of the single control doesn't make any difference, debugging step by step confirms that things go wrong when drawing the controls within the private system form classes.
I am creating a dedicated browser to be used exclusively on a single program located on my hard drive. Security is not a concern as the webbrowser URL will be set to the program's default web page path with no navigation options for going online. The program utilizes dynamic web pages with powerful search capabilities that require ActiveX controls. When I run my browser application, I get a series of security warning boxes stating:
Internet Explorer
An ActiveX control on this page might be unsafe to interact with other parts of the page. Do you want to allow this interaction?
Yes No
Clicking "Yes" allows me to continue and the program features work, but the recurrent warning message boxes are annoying. The default "script errors suppressed" property of the webbrowser control is "false." If I change it to "true" I don't get the security warning boxes but some of the search features on the web pages with ActiveX controls don't work properly.
Is there a way to programmatically enable ActiveX controls in the webbrowser control so that I can set the "script errors suppressed" property to "true" (hence no security warning message boxes) and still allow the ActiveX features to work properly? Or, set the "script errors suppressed" property to "false" and have my program automatically activate the "Yes" button each time a security warning message box is called by Internet Explorer? The goal is to get the ActiveX controls to work in webbrowser without having to click through the warnings.
I have a repeater which displays products. Users can select a Size - dropdownlist and an Amount - textbox. Then they press Order or Cancel. When they press Cancel I would like the values of Size and Amount to return to their default values.
Protected Sub lbtnCancel_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles lbtnCancel.Click
rpt.ProductList is the repeater name
lblFeedback.Text = ("")
lblFeedback.ForeColor = Drawing.Color.Black
End Sub
I am using VB.NET.
I want to find the values from a number of dropdown controls inside a repeater control. I eventually want to build a multidimensional array, so I can loop through each item and add them to a database table.

I have a label and dropdownlist inside a repeater. When I click a button outside the repeater I would like to access the label.Text value and ddl.SelectedIndex value.

how I can access lblProdName.Text and ddlSize.SelectedValue within:

I'm trying to speed up my Repeater so that not as much HTML has to be resent via the AJAX UpdatePanel on each call.
So here's what I have (a very much simplified version):
<asp:Repeater ID="rptContactSteps" runat="server">
<ItemTemplate>
<p>Script:<br /><%#mobjSDIT.FormatText(Eval("script"))%></p>
[Code]....
So, when I click 'btnSaveAndCompleteLastStep' I want all the UpdatePanel in 'rptContactSteps' to update. Having the UpdatePanel inside the ItemTemplate should help prevent having to re-load the html/text that populates the Eval("script") & Eval("notes"), since the value of these variables could be very large and over a 3G connection this could be very costly (in time & money).
I though by adding the async trigger it'd work as I have used this type of trigger before, but not when inside the Repeater. Currently the UpdatePanels aren't getting updated at all, except from the one from which the button was pressed.
In ASP.NET, using VB, how can i do this on the page itself, not in the code behind? [code]

I have a simple questionnaire system which shows a random number of questions to the user out of a certain total in my database.I have 2 separate tables: Questions and Alternatives (which are the options to answer) related by QuestionID field in both tables. I rendered such questionnaire using Nested Repeaters (parentRepeater for questions and childRepeater for the options) and it shows correctly on the page.Each option is a radio button which I had to use it as a HTML instead of the Standard Server Control <asp:RadioButton> because of the Dynamic ID problem inside a repeater.[code]What I don't know is how do I get all the questions answered by the user given that I don't know the QuestionIDs and the Alternative IDs since it's randomly generated and using a HTML input tags?
View 1 RepliesHowever, I recently tried to use it in a repeater. Essentially my company wants to have a number of different values displayed as the main repeater (no problem setting that up). When the user clicks on a field within that repeater, they would like the collapsible panel to open up and display the detail information for that piece of data. The details are within a sub repeater.The repeater functionality and the child repeater functionality are working perfectly. So the repeater and the child repeater aren't the issue. If I take the collapsible panel extender out the data displays perfectly.The problem is that once I start opening and closing the panels, the screen rendering starts to go crazy, and there seems to be no rhyme or reason for it.
For example, on the initial screen rendering I get seven entries. They look perfect. Each of the seven line up across the screen and no extraneous data is shown.I click to open the first row, and it displays great. No problem. But when I then click it again to close the first row, I only see the first four rows of data, then a huge white space with a few seemingly random characters, then the next 2 rows, a smaller whitespace, then the seventh row. I click to open the first row again and everything looks exactly as it should again. Again close, again 4 rows, whitespace, 2 rows whitespace, last row.I reload the page and everything is ok.
So now I click on the second row to open it and everything looks perfect. I close the second row and I get the exact same result.Has anyone ever tried to use the ajax collapsible panel inside a repeater? If so, have you encountered strange rendering behavior such as this? And if so, were you able to get it to work?Here's a stripped down version of the
