Set default RadGridView format

[Sharon Eden]

Hi,

I'm looking for a way to change the format of all the RadGridView instances in my application by default. Right now I would like to set the default font for the headers and rows and set the alignment. I have a method that is doing it and I'm using it for every RadGridView I'm creating, but I'm looking for something that will change all newly created grid view (just like the RadGridLocalizationProvider). I guess I can inherit the RadGridView and override some properties and event handler but is there a "built in" approach?

One more thing (please), Is there a way to set the column width as specified percentage of the table width?

Thanks,

Sharon.

Any news about this one :-) ?

Hi Sharon Eden,

Thank you for the questions.

Yes, you can inherit RadGridView class and set the desired settings in your custom grid class. Please, consider the following code as example:

class CustomGridView : RadGridView
{
    Font _myFont = new Font("Ariel", 10, FontStyle.Regular);
    public CustomGridView() :
        base()
    {
        this.GridElement.Font = new Font(_myFont, FontStyle.Bold);
        this.CellFormatting += new CellFormattingEventHandler(CustomGridView_CellFormatting);
    }
    void CustomGridView_CellFormatting(object sender, CellFormattingEventArgs e)
    {
        e.CellElement.Font = _myFont;
    }
    public override string ThemeClassName
    {
        get
        {
            return typeof(RadGridView).FullName;
        }
    }
}

In regards to the build-in way, you can achieve your requirement by modifying the existing RadGridView ControlDefault theme. If you decide to follow this approach write, back and I will provide you with the necessary instructions.

As to your second question, RadGridView does not support setting column width as percentage, but you can easily implement such a scenario yourself by using SizeChanged event:

void radGridView1_SizeChanged(object sender, EventArgs e)
{
    SetColumnSize();
}
private void Form1_Load(object sender, EventArgs e)
{
    SetColumnSize();
}
void SetColumnSize()
{
    this.radGridView1.Columns[0].Width = this.radGridView1.GridElement.Size.Width / 10;
}

Let me know if you have any other questions.

Hi Martin,

Thanks for your response.

I think I prefer to theme modification approach and I'll appreciate further assistance. By the way, I'm not using the default theme but rather the "Office2010" theme.

Thanks for the second answer too.

Sharon.

Hi Sharon Eden,

Thank you for getting back to us.

In order to change the Font properties of RadGridView Office2010 theme, please follow these steps:
1. Open Visual Style Builder.
2. From the main menu choose File >> Export Build-in Themes. This option will export all predefined Telerik themes as theme packages.
3. From the main menu choose File >> Open Package and choose the Office2010.tssp package that you have just exported.
4. Set the Font property of the appropriate rows in the RadGridView control.
5. Save your package and then load it in your project as it is described here.

You can also refer to the following articles concerning the new Visual Style Builder:
http://www.telerik.com/help/winforms/vsb_overview.html
http://www.telerik.com/help/winforms/vsb_workingwithrepositoryitems.html
http://www.telerik.com/help/winforms/vsb_fontrepositoryitem.html

Please note, however, that you should set the TextAlignment preferences in code. It will be best if you create a RadGridView descendant and set the desired alignment there:

public class MyGridView : RadGridView
{
    public MyGridView()
    {
        this.ViewCellFormatting += new CellFormattingEventHandler(MyGridView_ViewCellFormatting);
    }

    void MyGridView_ViewCellFormatting(object sender, CellFormattingEventArgs e)
    {
        if (e.CellElement is GridHeaderCellElement)
        {
            e.CellElement.TextAlignment = ContentAlignment.MiddleRight;
        }
        else if (e.CellElement is GridDataCellElement)
        {
            e.CellElement.TextAlignment = ContentAlignment.BottomLeft;
        }
    }

    public override string ThemeClassName
    {
        get
        {
            return typeof(RadGridView).FullName;
        }

    }
}

I hope this helps. If you have additional questions, feel free to contact me.

All the best,

Hi,
I'm looking for a way to change the format of group panel and the text of it , also i wont to change the format of grid header
can any one help me in that
thanks,
Rasha.

Hi Rasha Abdelhameed,

If I have understood your question correctly, you want to modify the visual appearance of the group panel and the grid header parts. In this case you can use the Visual Style Builder tool. For additional information about it, please refer to the following support resources:
http://www.telerik.com/help/winforms/vsb_overview.html
http://www.telerik.com/help/winforms/vsb_workingwithrepositoryitems.html
http://www.telerik.com/help/winforms/vsb_propertyprecendence.html
http://www.telerik.com/help/winforms/styling_radribbonbar.html

Basically, you need to change the properties of GridTableHeaderRowElement/GridTableHeaderCellElement and GridGroupPanel. The latter can be accessed when RadGridView is in grouped preview mode. In order to apply this mode, right-click on the RadGridView control in the Controls Structure window and choose Show Grouping View.

If you have any specific questions during the process of modifying the visual appearance of RadGridView, feel free to contact me.

All the best,
