Can't resize column with TextTrimming="WordEllipse" and Width="*"

[Abdulrahman Omran]

Hi,

I will try to explain the problem i'm having briefly. Basically, I'm trying to have one column in the grid to take all available space and if the text exceeds the max possilbe width then the text will be trimmed.

I have this line in my xaml:

<telerik:GridViewDataColumn Width="*" IsReadOnly="True" IsGroupable="True" TextAlignment="Left" DataMemberBinding="{Binding IntComments, Mode=TwoWay, ValidatesOnDataErrors=False}" Header="Internal Comment" TextTrimming="WordEllipsis" >the 

This works as expected. However, it introduces another problem. When the user increases the width of the column then this becomes the new MinWidth and the user can't decrease the width of the column ! ..

I hope there is a solution for this problem.

Thank you,
Abdul

Hello Abdul,

 


Generally the behavior you described is the expected one. When you set the Width property of a column to star ("*") it will fill the available space and TextTrimming will not work for this column, which is normally. You have to set a fixed width for that column in order to get it work.

Hi,

I guess I didn't explain myself well enough in the previous post.

I meant that the column now is stretching to fill the available space and the trimming is also working. This isn't a problem rather as you described it, it's the expected behaviour.

The problem is that the user now can't resize the column. Lets say i have extended the column to be 600 px wide so that the scrollbar is shown and now  I want to make the column width smaller, the column wouldn't resize. I can't increase the width but not decrease it.


Thank you.

Hello Abdulrahman,

 

We have spent some time to investigate what might be causing this behavior. Indeed a single star sized column cannot be increased/decreased by design. You should add an additional star-size column and everything should work as expected:

<telerik:RadGridView x:Name="radGridView" AutoGenerateColumns="False" ItemsSource="{Binding Collection}">
            <telerik:RadGridView.Columns>
                <telerik:GridViewDataColumn Header="OP1" Width="0.8*" TextTrimming="WordEllipsis"   DataMemberBinding="{Binding Property1}"/>
                <telerik:GridViewDataColumn Header="OP1" Width="0.2*" TextTrimming="WordEllipsis" DataMemberBinding="{Binding Property1}"/>
            </telerik:RadGridView.Columns>
</telerik:RadGridView>

Within this definiton the Width of the first column will be 0.8 percent of the available space, the second one is 0.2 percent of the available space.

In a similar way you may arrange the rest columns in your RadGridView. 

Hope this helps!
