Hi,
When the program execute the following codes:
 this.radGridView1.Rows[1].Cells[1].Style.DrawFill = true;
 his.radGridView1.Rows[1].Cells[1].Style.NumberOfColors = 1;
 this.radGridView1.Rows[1].Cells[1].Style.CustomizeFill = true;
 this.radGridView1.Rows[1].Cells[1].Style.BackColor = Color.Brown;

all the cells of the second row will trig the cellFormatting event. The performace is low.

Can we avoid it ,and only make the above cell to trig the cellformatting event?


Regrads!

I am developing an application where I use the RadGridView to display information from various stores. I use a GridView and show only the information of one store at a time.

In CellFormating'm formatting the text of GridView and am placing an image in the GridView cells when it has a note or comment.

The problem with it is that sometimes CellFormatting puts the image of the note in cells where it is not and does not remove the image of the note when changing store. The data in the GridView if the images are updated but the notes are not removed.

My code is as follows:

//----- Implementación del evento para el formateo de las celdas -----//
private void rgvResOper_CellFormatting(object sender, CellFormattingEventArgs e)
{
int iRenglon, iColumna, iRenCom, iColCom, iElemento1;
string sDato;
Font MiFont001 = new Font(new FontFamily("Verdana"), 6.0F, FontStyle.Bold);

try
{
Cursor.Current = Cursors.WaitCursor;

if (e.CellElement.ViewTemplate.Caption == "Información de las Cuentas Contables afectadas por la Póliza")
{
//e.CellElement.DrawFill = true;

e.CellElement.BackColor = Color.FromArgb(240, 240, 255);
e.CellElement.TableElement.RowHeight = 17;
e.CellElement.NumberOfColors = 1;
}
else if (e.CellElement.ViewTemplate.Caption == "Información de las Pólizas que conforman el Concepto")
{
//e.CellElement.DrawFill = true;

e.CellElement.BackColor = Color.FromArgb(240, 255, 240);
e.CellElement.TableElement.RowHeight = 18;
e.CellElement.NumberOfColors = 1;
}
else if (e.CellElement.ViewTemplate.Caption == "")
{
if (e.CellElement.ColumnInfo.HeaderText == "IdConcepto")
{
e.CellElement.Font = MiFont001;
}

if (e.CellElement.Text == "GROSS PROFIT" ||
e.CellElement.Text == "COST" ||
e.CellElement.Text == "OTHERS COST / PROFITS" ||
e.CellElement.Text == "EXTRA POSITIONS" ||

e.CellElement.Text == "CASH-FLOW Before Corporate Tax" ||

Can you help me please.

I'm trying to get a winforms application to use a secondary y axis.  A thread from 2008 seems to indicate this is possible, and a thread from 2011 seems to indicate that its not possible.

Can I have a secondary Y axis in a winforms app?  If so, how...



Thank you -
Scott

Similar to Office 2010 - I would like to have the text "File" appear on the tab/button that displays the Backstage view, rather than an image. Is this possible? If so, how is it done?

Hello,

I am developing a windows application. Previously I installed telerik controls using installer and all controls were working fine. After I formatted my system I downloaded all required .dll and put them all in assemblies and added all telerik controls in toolbox by drag and drop. I can build my project but when I try to click telerik control I cannot select them. Also when I add new control it gets added in the area where Rad Themes appear; but the control does not appear on the win form.

Also previously I could see Rad Windows Form Application in Add New Project dialog which I don't see now. I am not able to add RadForm now. Thank you for any help.

Hello Telerik


I use application.I want to change drop down menu location & size of menu item. I want to display like "Pic1" image. But it is displaying like "Pic2" image. How can I change this?

I have been messing around with the q2 2012 release and have noticed that for some reason when I attach a theme to a control I can no longer change the font information. If I add a them to a menu bar and then want the main menu items to be larger and bold it will not let me change the values. If I remove the theme I see the font changes. Is there something I am doing wrong?

I have just started t o mess around with the ribbon control and I seem to be having an odd issue.  I have a User Control that I created with a radgrid on it.  When I load the control into a windows form it looks correct but when I load the cam user control into the main panel of a ribbon form the grid looks like it is disabled.  It works fine, but it is faded and hard to read.  Is there some setting with the ribbon that is doing this?

Good afternoon,
Update my project with Q2 2012 SP2 version, mark me in my project fails the next instruction. Me pudieran decir que cambio?

this.radGridView1.MasterTemplate.AutoSizeColumnsMode = Telerik.WinControls.UI.GridViewAutoSizeColumnsMode.Fill;
