I have the following problem:

I open big window with a radgrid. and when i resize the window (reduce the width) the grid's margins is outside the window.
It happens with all grids. I tried to "play" with width, max width etc but it doesn't help

See attached file.

This is the code for opening the window

        private int resolutionWidth = 1920;
        private int resolutionHeight = 1200;

            var mainWindow = new TaskbarRadWindow
            {
                Content = contect,
                Header = title,
                WindowState = WindowState.Normal,
                Width = resolutionWidth,
                Height = resolutionHeight,
                MaxWidth = resolutionWidth,
                MaxHeight = resolutionHeight,
            };

Thanks,
Ofer

Hello Ofer Alper,

 Could you please send us a sample project that reproduces the problem. This would be of great help in investigating what the problem is.

I can't attach my solution and can't submit support ticket. do you have a email when i can send it?

Another severe problem that i have it that i cannot enlarge the grid width, although i didn't set MaxWidth.

Here is a sample of grid. But it happens in all rad grids. I can't resize the last column, it behaves as if the MaxWidth is set.

I also checked in the code and the MaxWidth is not set (i.e. infinity)

<UserControl x:Class="gridtest.GridTest"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:telerikGrid="clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls.GridView"
    Height="1000" Width="1000">
    <Canvas>
        <telerikGrid:RadGridView x:Name="radGridTest" AutoGenerateColumns="False" Width="1500" Height="1000" Canvas.Left="0" Canvas.Top="0">
            <telerikGrid:RadGridView.Columns>

                <telerikGrid:GridViewDataColumn
                Width="100" Header="C2"
                DataMemberBinding="{Binding Mode=OneWay, Path=x2}" IsReadOnly="True" />


                <telerikGrid:GridViewDataColumn
                Width="100" Header="C3"
                DataMemberBinding="{Binding Mode=OneWay, Path=x2}" IsReadOnly="True" />
            </telerikGrid:RadGridView.Columns>
        </telerikGrid:RadGridView>

    </Canvas>
</UserControl>

Hello Ofer Alper,

  Do you put this UserControl into a RadWindow? If yes, please notice that the UserControl has its Width and Height properties set to 100. The GridView has also its Width and Height properties set. This might be the reason why it doesn't resize.

About attaching the project - unfortunately our forums doesn't support attaching projects.

All the best,

Hi Ofer Alper,

 You specify them in the XAML you sent. Here:

<UserControl x:Class="gridtest.GridTest"
    xmlns:telerikGrid="clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls.GridView"
    Height="1000" Width="1000">
    <Canvas>
        <telerikGrid:RadGridView x:Name="radGridTest" AutoGenerateColumns="False" Width="1500" Height="1000" Canvas.Left="0" Canvas.Top="0">
            <telerikGrid:RadGridView.Columns>
 
                <telerikGrid:GridViewDataColumn
                Width="100" Header="C2"
                DataMemberBinding="{Binding Mode=OneWay, Path=x2}" IsReadOnly="True" />
 
 
                <telerikGrid:GridViewDataColumn
                Width="100" Header="C3"
                DataMemberBinding="{Binding Mode=OneWay, Path=x2}" IsReadOnly="True" />
            </telerikGrid:RadGridView.Columns>
        </telerikGrid:RadGridView>
 
    </Canvas>
</UserControl>
The Width and Height of both - the UserControl and the RadGridView are specified.

Best wishes,

It still doesn't let me to enlarge the grid width.
I need that the user will be able to resize the columns and enlarge the grid if necessary.

I did not set MaxWidth of the userControl or on the Grid

Hello Ofer Alper,

I just noticed that you are using Canvas panel - it causes the problem (besides the Width and Height of the UserControl and the GridView). Please, refer to the attached project - I changed the Canvas with Grid panel.

I tried grid also it is not working. I can't resize (enlarge my radgrid).

My code is very simple and it is very easy to reproduce  i do the following :

1) Open Window
2) create a new GridTest user control
3) set the GridTest as the content of this window.


I didn't define maxWidth of the grid or of the user control. I tried every possible parameter (add width to the user control, remove width from the user control etc)

Please Help.

The code of the user control
<UserControl x:Name="gridcontrol"
   x:Class="SampleWpfDataGrid.GridTest"
   xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
   xmlns:telerikGrid="clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls.GridView"
   Width="1800" Height="1800"          
>
    <Grid>

        <telerikGrid:RadGridView x:Name="radGridTest" ColumnReordered="radGridTest_ColumnReordered" AutoGenerateColumns="False" DataLoadMode="ASynchronous" Width="1000" Height="1000" Opacity="1.0">
            <telerikGrid:RadGridView.Columns>

                <telerikGrid:GridViewDataColumn
                Width="100" Header="C2"
                DataMemberBinding="{Binding Mode=OneWay, Path=x2}" IsReadOnly="True" />

                <telerikGrid:GridViewDataColumn
                Width="100" Header="C3"
                DataMemberBinding="{Binding Mode=OneWay, Path=x2}" IsReadOnly="True" />

            </telerikGrid:RadGridView.Columns>
        </telerikGrid:RadGridView>
    </Grid>
</UserControl>
