Hi - I am using WinForms Q2 2008 and am unable to apply the Vista Theme to a RadForm. I can set other Themes, like Desert and Aqua, but when I set ThemeName to Vista, it seems to get ignored. Any help appreciated.

CopyTo doesn't work with all rows

I have a scenario on a form where I need to save all the rows in the form to a collection in memory to save any changes a user has made prior to saving them to a database, but still allow them to swap between different views.

I'm using the SelectionChanged event to handle storing the data, but I have found that calling GridView.Rows.CopyTo() doesn't work. I get a GridViewDataRowInfo[] array that is populated with null values.

Sample code is below:

_batchTrays = new Dictionary<int, GridViewDataRowInfo[]>();

int batchNumber = Convert.ToInt32(grid.CurrentRow.Cells["BatchNumber"].Value);

_batchTrays[batchNumber] =  new GridViewDataRowInfo[batchTraysGrid.Rows.Count];

                    batchTraysGrid.Rows.CopyTo(_batchTrays[batchNumber], 0);

this gives me an array populate with null values.

is there a preferred way to accomplish what I am trying to do?

Row Selection

Hi

I need to know the best way to call a client detail form by clicking on a row in a RadGridView. I'm not sure what code to put in the Click event.

My RadGridView shows 15 columns of Client data and stores the Client ID column in the first column of the Grid. I want to click on a row and then call a detail form and pass it the selected Client's ID.

I'm using VB.Net.

Many thanks

SelectionChanged Event and Manually adding rows

I'm currently using the RadGridView.Rows.Add(new object[]) method to create a new row in a GridView on a button click. Calling the Rows.Add method will trigger the SelectionChanged event twice, as expected, but a problem occurs when I try to access the properties of the newly added row via the RadGridView.SelectedRows[0].Cells[0] properties. I only get default values for the cells, and not the actual values that I provided in the Rows.Add(new object[]) call.

Is this a known issue, or is there a different way to get the Objects that have been added?

Thanks,
Chris

Unable to use RadForm

I am developing on a Windows Server 2003 box using Visual Studio 2005. I installed the RadControls for WinForms 2008 SP1 on top of a previous Winforms installation from early 2007. My existing WinForm application works fine after installing the new Telerik update. However, I'm not seeing the RadForm class. I created a new project, added a reference to Telerik.WinControls to my new project and then proceeded to edit the default form to inherit from Telerik.WinControls.RadForm. The problem is "RadForm" is in red because VS2005 cannot find a reference to the class. I thought maybe I had to add a using clause but that didn't seem to help. Did my installation not work correctly, fogetting to register something, or am missing something simple? Thanks.

RadTreeView Inside a DLL

Hi,

I have created a framework for our application (CMXUIFramework.Dll). All user controls are in this dll, which may comprise of one of more UI controls. This DLL can be now referenced for a stand alone app as well as an Outlook integration app. On one of the controls I have used is Microsoft’s TreeView control and everything works fine, however, when I replace the Microsoft’s TreeViewControl with a Telerik Treeview control, at runtime I get object not set to an instance of an object.

Is there anything I should know about when displaying Telerik’s controls on a form in this manor?

Thanks

GridElement Begin and EndUpdate Does not seem to always work

I have a Windows Form GridView object that I am populating. I need to allow the user to change the order of items in the list. To do this, I have two buttons, MoveUp and MoveDown to let them. For simplicity sake, I have left out a lot of error checking code from my post.

My problem is that I am calling the GridElement.BeginUpdate() and GridElement.EndUpdate() methods, and for the MoveUp it works just fine, however, oddly enough, the MoveDown causes a flicker effect, which is not supposed to happen (I think) if I am using these methods correctly.

Here is the portion of my code that is doing this action, as you can see the same code is running in both instances, I am just passing in a different change:

private

void btnMoveUp_Click(object sender, EventArgs e)
{
MoveCurrentItem(-1);
}

private void btnMoveDown_Click(object sender, EventArgs e)
{
MoveCurrentItem(1);
}

private void MoveCurrentItem(int indexChange)
{
    if (radgvScriptsList.SelectedRows.Count == 1)
    {
        radgvScriptsList.GridElement.BeginUpdate();

        MultiScriptFile file = GetSelectedFile();
        int oldIndex = Files.IndexOf(file);
        Files.Remove(file);
        Files.Insert((oldIndex + indexChange), file);
        radgvScriptsList.Rows[(oldIndex + indexChange)].IsCurrent = true;

        radgvScriptsList.GridElement.EndUpdate();
    }
}

RadGridView AutoGenerateColumns Problem

What I'm trying to do is AutoGenerateColumns at the end of the predetermined columns of the radgrid. It works fine the first time the form loads, but if i change the dataset to bring back an extra column of AutoGenerated data the grid doesn't show any of the AutoGeneratedColumns anymore. However if I remove an AutoGenerated column of data from the dataset the grid will still display the correct AutoGenerated columns of data.

I have tried setting the radGrid.DataSource to null as well as the MasterTemplate.DataSource, before I rebind the grid with the new fields for the AutoGeneratedColumns, but that doesn't seem to work either...
