RadMenu MdiList

Hi

I have a shaped form and set a menu item called 'Window' with .MDIList property = TRUE so that it shows a list of all child forms currently open within the MDI.

However, the menu is showing the form Name e.g. "frmPerson" and not the text in the forms Title bar so if we have multiple instance of "frmPerson" open within the MDI it shows "frmPerson" multiple times in the menu and not what is contained in the forms title bar which identifies the individual forms e.g "Person - Joe Bloggs"

The forms .Text name property is set to the details I would expect to see in the MDIList under Window but it appears to use the .Text value that is set on the form at design time?

Any idea how I can change this?

Many Thanks
Steve

CommandBar Samples

How would I use "Text Only" buttons?

Any Examples using the CommandHostItem would be great. The help talks about the HostedElement Property, but I don't see it in the designer properties window. Can we really host any RadControl?

Thanks

Grid scrolling to top using DeferRefresh

Hello,

I have a hierarchical grid with about 8000 rows. Based on user interaction I have to update values of specific cell, which I do by looping through the selected rows. There is a conditional formatting on the specific cell which changes the background depending on the value.

My problem is the following ; if I use the following statement it takes too long :

foreach (GridViewRowInfo row in this.radGridView1.SelectedRows)

{

row.Cells["MY_CELL"].Value = "newValue";

}

Now if I use DeferRefresh() the speed is drastically improved, but the grid scrolls back all the way to the top when it is done :

using (this.radGridView1.DeferRefresh())

{

foreach (GridViewRowInfo row in this.radGridView1.SelectedRows)

{

row.Cells["MY_CELL"].Value = "newValue";

}

I don't know if it is normal behavior, or if there is a way to avoid scrolling back all the way to the top AND keeping the same run time I have with DeferRefresh().

EDIT : I also tried using BeginUpdate() and EndUpdate() which result in the same scrolling behavior.

Thank you for your help !

TextBoxElement in Ribbon

Hello,

I have a form with a RadRibbonBar and a RadGridView.
Within the toolbar I have programmatically added a RadTextBoxElement (and a button) in order to search through the grid.
Everything is working perfectly well except when I try to implement the CTRL+F shortcut. The event do get fired and I am able to catch the requested action, but then I cannot get the textbox to focus.

I have tried both mytextboxelement.TextBoxItem.Focus() and mytextboxelement.Focus() with no success.

private void searchKeyDown(object sender, KeyEventArgs e)

{

if(e.KeyCode == Keys.F3)

btnSearch_Click(null, null);

else if (e.KeyCode == Keys.F && e.Modifiers == Keys.Control)

{

RadTextBoxElement txt = (RadTextBoxElement)this.radRibbonBarButtonGroup1.Items[0];

txt.TextBoxItem.Focus();

}

Any idea if I'm doing something wrong or if there is a problem ?

Thank you,

Datatable or Unbound Mode bind with images?

Hi,

I am a little bit confuse as in how to bind images to a RadDropDownList. I can bind with a data table. But I don't know how to bind images to my items. So, do I have to use the Unbound Mode to bind each item in my data table and then bind images while I am iterate through the data table? I can't find a good example in the documents for this.

Thank you for the help.

Good day.

Multi column combo data binding

Hi... I am using the Q3 2009 version of your controls and I am trying to understand your data binding. What I would like to do is to bind the combo to a single field in one table but display a list based on another. I am just migrating to the telerik controls and .Net and in other ActivieX controls (non telerik) they had two properties that allows me to accomplish this. They combo boxes had a RowSource and a DataSource. The model was simple for me to understand. I would bind the control to the data source but, use the row source for the list. For the Telerik control I have noticed that it only has the Data source property. And Until that is set , I cannot set the Value Member or the Display Member properites.
Please can you help me to accomplish this? Where am I going wrong or not underdstanding

Thank you.

Compatability with 3rd party controls? HELP!

Clark

Posted on 1 day ago

I'm trialing the RadControls for Winforms and I have two technical questions that will determine whether I purchase or not:

1. If I decide to use a RadForm in my application, how does the Telerik Presentation Framework handle other 3rd party controls I may want to place on the form? I want to take advantage of the WFP-like enhanced UI, but I don't want my non-Telerik controls to look different. Does the TPF automatically adjust the appearance of 3rd party controls on a RadForm?

2. One of the issues I've always had in the past when programming WinForms applications that are distributed to end-users is resolution compatability with all of the different possible monitors used. This has caused cases of wwhere windows are truncated/cropped, or where they appear too small or too large. Does a RADForm automatically take end-user monitor resolution into consideration and adjust the display of the form size automatically?
