Specifying GridViewMaskBoxColumn maximum length when using a "P" Mask

I have several columns in a RadGridView control available for editing a percentage value. The "P" mask works great using a GridViewTextBoxColumn except I can't figure out how to set a limit on the number of digits a user can enter into a cell. There USED to be a MaxLength property to define the maximum length, but in the recent versions of the Rad Controls, this property has been removed ... no longer available. Can you tell me how I can maintain the nice formatting that the "P" mask provides (while editing) and still specify the maximum length of the string of digits the user is allowed to enter?

Disable Checkboxes in Treeview but keep them visible

Hi Guys

I recently added a radiobutton element to the standard RadComboBoxItem by overriding the CreateChildElements() method on the control.

I was wondering if there was an override on the RadTreeNode which I could use to disable the checkbox which displays on a Node. I want the user to be able to see the checked state without being able to change it? Could I add a method to an inherited node which would allow me to use code like this.

RadCustomTreeNode.Checkbox.Enabled = false;"

Many thanks in advance

Regards
Ian Carson

Display Grid Lines on Specific Theme

I am trying to display gridlines in the Detail View of a ListView control. I am currently using the VisualStudio2012Dark theme and it does not show the gridlines that separate each row. I have watched several of your webinars on the themebuilder but cannot figure out how to modify the theme to have gridlines.

Thanks

RadGrid - Using a checkbox to add rows to the selectedrows collection

I've been reading through the tutorials and forums to see if this is possible or if maybe my approach is wrong. Here's what i am doing.

I am using a pretty simple grid with an id number in the second column. The first column is a checkbox cell. All I want to do is to check the checkbox of say 4 or 5 of the rows and them ask the grid which rows have been selected. Does the grid's selected rows collection maintain this for me or do I have to code this myself to store the key's seperately, which is easy enough to do. But from looking at the various forum threads, it looks like the grid will do this if you allow mulitple row selections. But when I set this and check the selectedrows collection, it is always empty.

This sounds like a VERY common question and approach, but I cannot find the anwser. What I would like to do is something like the following. This doesn't work because the selectedrows(0) is always empty. In fact, when I view just the selectedrows, the count is always 0. So the grid is not keeping track of this for me.

I do have the option turned on to select multiple rows. I can add my own logic to track this, but I think the grid is handling it based on other threads and the sample code below.

Private Sub dgvLoanRestore_ValueChanged(sender As System.Object, e As System.EventArgs) Handles dgvLoanRestore.ValueChanged

dgvLoanRestore.EndEdit()

Dim selectedRows As New List(Of GridViewDataRowInfo)

Dim item As Object = dgvLoanBackup.SelectedRows(0).DataBoundItem

selectedRows.Clear()

selectedRows.Add(item)

' Recount rows selected (i.e. the number of checked checkboxes in the grid)

lblSelectedRowCount.Text = selectedRows.Count.ToString()

End Sub

Hi,

radDropDownListTempo.Items.Add(new RadListDataItem() { Text = "Item 1", Tag = "1", Selected = true

, TextAlignment = ContentAlignment.MiddleCenter, Image = global::.....Resources.Clock32, ImageAlignment =ContentAlignment.MiddleLeft});

radDropDownListTempo.Items.Add(new RadListDataItem() { Text = "Item 2", Tag = "7", Selected = false

Export to Pdf

I see that for asp.net you can set your page format (like footer, page number) when you export a grid to pdf. I see it was added relatively recently. Do you have the same functionality for winforms? If so how do you do it?
If the function is not added when do you think the functionality could be added?
Thank you for your time and help.

a couple of questions

1.I added programmatically a button to the navigator bar. Where can I find the handler for the newly created button so I can add my code there?
2.How do you add to the new created button the save image?
3.I don't wish the users to add/modify the buttons they can see on the pdf navigator. What should I do to disallow this?

Thank you for your help and time.
