FilterChanging and GridViewCheckBoxColumn

I'm need disappear value in filter when filter changing.
Example:
void RadGridViewQuestions_FilterChanging(object sender, GridViewCollectionChangingEventArgs e)
        {
            e.Cancel = true;
        }

When this event calls GridViewCheckBoxColumn and above specified method is fulfilled - value in the filter does not disappear. If this event is called by others Columns after method performance - values disappear.

Resize performance on DockingManager as MDI controller

With a dockingManager that isAuto-detecting MDI children on a form, I've noticed that when resizing the parent form there is a considerable performance hit when there are several MDI children hosted on the form. It appears that the docking manager is doing the resize.

Anyone have any suggestions for ways to speed this up? I thought about cancelling the resize events of the forms that are not visible, but then I would have to know what to resize them to when the user activates their tab.

Thanks,
Adam

Dynamicalliy create RadTabStrip control

Hi,

I have to dynamically create a RadTabStrip control inside form (form MDI application).
I used this code:
-------------------------------------------------------------------
Telerik.WinControls.UI.RadTabStrip radTabStrip = new Telerik.WinControls.UI.RadTabStrip();

radTabStrip.BackColor = System.Drawing.Color.FromArgb(((int)(((byte)(191)))), ((int)(((byte)(219)))), ((int)(((byte)(254)))));
radTabStrip.Dock = DockStyle.Fill;

Telerik.WinControls.UI.TabItem t1 = new Telerik.WinControls.UI.TabItem("Tab 1");
Telerik.WinControls.UI.TabItem t2 = new Telerik.WinControls.UI.TabItem("Tab 2");
Telerik.WinControls.UI.TabItem t3 = new Telerik.WinControls.UI.TabItem("Tab 3");

radTabStrip.Items.AddRange(new Telerik.WinControls.RadItem[] { t1, t2, t3 });

t1.ContentPanel.BackColor = System.Drawing.Color.Transparent;
t2.ContentPanel.BackColor = System.Drawing.Color.Transparent;
t3.ContentPanel.BackColor = System.Drawing.Color.Transparent;

Button b1, b2, b3;
b1 = new Button(); b2 = new Button(); b3 = new Button();
b1.Text = "Bottone 1"; b2.Text = "Bottone 2"; b3.Text = "Bottone 3";
t1.ContentPanel.Controls.Add(b1);
t2.ContentPanel.Controls.Add(b2);
t3.ContentPanel.Controls.Add(b3);

radTabStrip.TabsPosition = Telerik.WinControls.UI.TabPositions.Bottom;

this.Controls.Add(radTabStrip);
-------------------------------------------------------------------
This code works, but the control isn't displayed fine! In particular tab buttons are not displayed as they are displayed when i use designer to create RadTabStrip.

What is the best way to solve my problem?
Thank you very much for support.

Bind column to different field per row, depending on 'selector'-field

Hi, I'm evaluating the trial and one thing we'd like to do is the following:

We'd like to have a db-table with columns e.g. 'intField', 'floatField', 'textField' and a 'type-selector' of type int that is indicating which of the db-columns the grid-column should be bound to, different for each row.

With the MS-DataGridView I could derive a new column hosting a derived cell, and in this cell then just overwrite GetValue and SetValue - more or less... ;-)

I haven't found the necessary overwrites with for RadGridView and friends (yet?), so: how would I do this with the RadGridView?

TIA, Juergen

DateColumn Doesn't sort

I have a date column which is in MM/dd/yyyy format. This doesnt sort ascending or descending for all the grids in my application. I am sure what I have done is right. Still it doesnt sort right when I click on header. Please help. One way of doing it is after binding the data source by adding

radgvSixMonthPurchases.Columns[

"transactionDate"].FormatString = "{0:MM/dd/yyyy}";

and othe way is through cell formatting like:

private void radgvSixMonthPurchases_CellFormatting(object sender, Telerik.WinControls.UI.CellFormattingEventArgs e){
if (e.CellElement is GridDataCellElement)
{
Font font = new Font("Tahoma", 6.75F);
e.CellElement.Font = font;
if (((GridViewDataColumn)e.CellElement.ColumnInfo).FieldName == "transactionDate")
{
if (!e.CellElement.Text.StartsWith("0:"))
{
DateTime temp = DateTime.Parse(e.CellElement.Text);
e.CellElement.Text = temp.ToString("MM/dd/yyyy");
}
Font newfont = new Font("Tahoma", 7, FontStyle.Underline);
e.CellElement.Font = newfont;
e.CellElement.ForeColor = Color.Blue;
}
}
