Hello,
I have tried to customing a gridview row with html view like it is recommended in a few posts.
The result is not which i want, I want something like this:

[--colLeft--][----------------------col-----------------------]
[------------------------------------col-------------------------]
[--colLeft--][--colLeft--][--colLeft--][------col--------]

When I resize the gridviewI want to colLeft stay at left like:

[--colLeft--][----------------------------------------col------------------------------------]
[-----------------------------------------col---------------------------------------------------]
[--colLeft--][--colLeft--][--colLeft--][-----------------col----------------------------]

To make that I have used this C# code:

// Row struct in html view

this.htmlView = new HtmlViewDefinition();

this.htmlView.RowTemplate.Rows.Add(new RowDefinition());

this.htmlView.RowTemplate.Rows[0].Cells.Add(new CellDefinition("IsLocked", 0, 1, 1));

this.htmlView.RowTemplate.Rows[0].Cells.Add(new CellDefinition("name", 0, 3, 1));

this.htmlView.RowTemplate.Rows[1].Cells.Add(new CellDefinition("details", 0, 4, 1));

this.htmlView.RowTemplate.Rows[2].Cells.Add(new CellDefinition("preview", 0, 1, 1));

this.htmlView.RowTemplate.Rows[2].Cells.Add(new CellDefinition("insert", 0, 1, 1));

this.htmlView.RowTemplate.Rows[2].Cells.Add(new CellDefinition("remove", 0, 1, 1));

this.htmlView.RowTemplate.Rows[2].Cells.Add(new CellDefinition("link", 0, 1, 1));

It works but when I'm resizing the gridview, cells are automaticly re-arranged (size and location) and centered so columns I want to fix on the left side (colLeft) moving. Like that:

[-------colLeft------][----------------------------------------col----------------------------------------------------]
[-----------------------------------------col----------------------------------------------------------------------------]
[-------colLeft------][-------colLeft------][------colLeft------][-----------------col----------------------------]

My question is How can I fix columns size to X pixels and location to left to make what I want?

Thanks

Hi Anthony,

Thank you for writing.

Currently, RadGridView does not support fixed column widths when using a HTML view definition. I have logged this as a feature request in our Public Issue Tracking System - PITS. You can track its progress, subscribe for status change alerts and add your vote/comment on the following link - PITS Feature.

I have updated your Telerik Points for the suggestion.

Should you have further questions, I would be glad to help.

Hi Ivan,

I come back with a question in relation with my RadGridView.
I want to customize a text into a cell (simply to make it bold).
My problem is that my cell wrap the text when it is too long (it work perfectly with a non customized text) but when I customize the text, it continue out of the cell (look pictures, one is with non customize text and the other with bold text).

I make it bold with html:

gridViewTextBoxColumn2.DisableHTMLRendering = false;

e.CellElement.Text = "<html><b>" + myText + "</b></html>";

My question is how to fix this issue ?

Thank you

Hello Anthony,

Thank you for writing back.

Due to the implementation of the HTML-like text formatting it cannot be clipped by elements. In your case a more suitable approach would be to use the CellFormatting event of RadGridView. Since you will be changing fonts we always advise our clients to create a font as a field or a singleton property and use this font for the formatting purposes. This is advisable as creation of Font objects is a heavy operation which can easily lead to memory leaks and performance degradation. Here is an example:

private Font boldFont = new Font(new FontFamily("Calibri"), 12.0F, FontStyle.Bold);

private void grid_CellFormatting(object sender, CellFormattingEventArgs e)

{

if (someCondition)

{

e.CellElement.Font = boldFont;

}

else

{

e.CellElement.ResetValue(LightVisualElement.FontProperty, Telerik.WinControls.ValueResetFlags.Local);

}

I hope this will be useful. Feel free to write back with further questions.
