I know how to add a item(checkbox) to a toolstrip dynamically, but I want to add a checkbox which is exists in a form. I've tried using the code
[Code]...
but this makes the already existing checkbox, go to the top left of screen and when the toolstrip is click it appears. So I want to add the checkbox to the menu, without going to top left corner,
How can I create a toolstrip in code and Add controls to it as required?

View 3 RepliesI want to make my webbrowser navigate to the clicked toolstrip item's text. for example:
Private Sub HistoryToolStripMenuItem_DropDownItemClicked(ByVal sender As Object, ByVal e As System.Windows.Forms.ToolStripItemClickedEventArgs) Handles HistoryToolStripMenuItem.DropDownItemClicked
[Code]......
I did a VB6 to VB.NET conversion and this line wasn't converted. I'm not sure what property to set that would replace Bevel. What could I use? statusBarMain.Items.Item("PercentBar").Bevel = System.Windows.Forms.Border3DStyle.SunkenOuter
View 2 RepliesI have a tool strip menu item who's collection is filled from a subroutine that loads all available com ports on the computer at for load. I know how to generate a click event for menu items that are filled, but not if they haven't been filled already. I guess it doesn't need to be a click event. It just needs to do something that I can get the .text and use it to configure a serial port.
View 6 RepliesI have created a search/query facility after watching one of Beth Messi's videos. I notice that we can convert the textboxes on the auto generated search toolstrip to buttons, comboxes, etc. So, when we wanna search for a data in the datagridview, we enter a keyword. I wonder if it is possible to change the textboxes to comboboxes and make it bind to the datasources, so that users can use the drop down, instead of typing?
View 6 RepliesI've got a dynamically filled datagrid view. When a user right clicks a cell in the datagridview, it opens a context menu, located by that cell. The context menu has two choices: A and B. I want to set the value of the cell to A if they pick A, and B if they pick B.I would like to pass the relevant cell as a field in the event args passed to ContextMenu's ToolStripItem.click. So the handler for ToolStripItem A's click event would read the relevant cell from the event args and set it to A , like this...
Private Sub A_Click(ByVal sender As System.Object, ByVal e As Customized System.EventArgs) Handles A.Click
e.relevantCell.Value=A
End Sub
how to pass a custom event arg. Or if there is some easier way to do this? I can't just use the X and Y coordinates, because the context menu/mouse won't necessary by over the relevant cell.

I am trying to use a checkbox that is dynamically declared in an .vb file that I am trying to write into my .aspx page. I am able to write a normal checkbox of <input type='checkbox /> from the .vb Class using Response.write, but it comes up blank when using <asp:Checkbox runat='server' />I need to pass whether or not the box is checked back to the server, because I am having to either approve something if one is checked, reject something if the other is checked or do nothing if neither are checked.
View 3 RepliesI would like to generate the checkbox list dynamically.For example against the list of employees(rowwise), provide the list of check box options (columnwise), the selected items will be stored in the database against the each employee. Since i am the new to .NET your guidance will help me to complete the task.
View 1 RepliesI really want to make use of the toolstrip and databinding but these two technologies keep conflicting with each other. I think the root cause is something to with the fact that the toolstrip buttons don't recieve focus in the normal way.
I invite you to try the following:-
1. Create a form and put some text boxes a tool strip with a save button on it.
2. Write a query or sproc to get a datatable back and bind your text boxes to the field in the datatable.
3. In the code behind your Save ToolStripButton put some code that makes an arbitrary change to a field on the dataset (it doesn't matter whther this field is bound to a text box or not). eg:-
m_DataTable.Rows(0).Item("CommissionRatePerc") = "0.0000"
4. Put a breakpoint in the save and run the form.
5. Make some changes in the text boxes. Do not leave the last text box but rather click save while a text box whose contents you have edited still has focus.
6. When your code hits the breakpoint, query the value of the data table field that is bound to the text box you were editing when you clicked save - it will still contain the unedited value. Unless you do something about it that unedited value is going to get saved back to your DB.
We did get around this problem by explicetely setting the focus to another control on the form before saving. That worked most of the time because it prompts the text box to flush it's value back to the datatable (nb EndEdit does not work, although you'd have expected it to). However, and this is the reason I suggested you add a line of code that changed a value in the underlying datatable in step 3, if you change a value in code in this way before the value from the text box get's flushed back then it doesn't seem to matter what you do, the user's current edit is simply lost. They will still show in the text box, though, leading your user to believe that the change has been committed when it hasn't. Our final solution is that we never ever change a value in the adtaset in the code behind our toolstrip buttons. That's working but it's a pretty big restriction.
