[VB.NET/Columns] Columns resize even when fixed width is set

[Michiel Peeters]

Current environment:

ASP.NET (3.5 / VB.NET)
Telerik Controls Q2 2010
Visual Studio 2010 Ultimate

Problem:

Currently I have a user control where the radgrid is placed on and gets dynamically loaded via the code behind of the user control. This radgrid contains 2 columns that have a fixed width of 30 Pixels. Somehow when I add an extra column (so my grid consists 3 columns) the first 2 columns gets also resized even when I have set those columns a fixed width by the HeaderStyle and even the ItemStyle property. I have also set my radgrid with the TableLayout fixed and in the scrolling I've set the staticheader to true (in the below code sample you see the current radgrid).

<telerik:RadGrid ID="RadGrid1" runat="server" AutoGenerateColumns="true" HeaderStyle-Wrap="false" EnableHeaderContextMenu="true"
EnableViewState="false" AllowPaging="true" PageSize="20" Skin="Default"
EnableEmbeddedScripts="false" EnableEmbeddedSkins="false" EnableEmbeddedBaseStylesheet="false" RegisterWithScriptManager="false"
AllowSorting="true" GroupingEnabled="false">
<MasterTableView TableLayout="Fixed" />
<PagerStyle AlwaysVisible="true" Mode="NextPrevAndNumeric" />
<ClientSettings AllowColumnsReorder="true" ReorderColumnsOnClient="true" ColumnsReorderMethod="Reorder"
        Resizing-AllowColumnResize="true" Resizing-ResizeGridOnColumnResize="true" >
        <Scrolling UseStaticHeaders="true" AllowScroll="true" ScrollHeight="20px" />
</ClientSettings>
</telerik:RadGrid>

When I move my screen to a greater screen with a resolution of 1920 those fixed columns are also getting resized which what I don't want.

Thank you in advance.

Hello Michiel,

Try setting the Resizable property to false for those columns which you do not want to resize and let me know how it goes.

Hello Pavlina,

I'm truly sorry, I forgot to mention that I've already set that property to false.

[Michiel Peeters]

This is now under the correct account. :)

Like I said before the property Resizable is already set to false.

Best Regards,
Michiel

Hi Michiel,

I already have answered your support ticket on the subject. for convenience I will paste my answer here as well:

The observed behavior is expected, although it may look otherwise.

By default, the TableLayout of the MasterTableView is "Auto", which means that columns expand according to their content. Setting TableLayout to "Fixed" leads to all columns having the same width and shrinking to fit the available space. This occurs unless you specify explicit column widths.

If all columns have a fixed pixel width, then the sum of all widths must match the RadGrid width, otherwise the columns expand to fill up the available space. In such cases it is good to leave one column without a width (e.g. the last one), so that it can adjust automatically.

Therefore, to resolve the problem you are facing you could leave at least one column with no width, so that it adjust automatically, according to the available space.

Additionally, I recommend that you examine the following forum thread, which describes the best practice for Grid and Column widths:
