Auto adjust GridView columns width ?

[Romain]

Hi,

I'm working with a GridView where some Editing cells are a lot wider than the Cell. The GridView resize correctly to fit the editing mode but doesn't resize correctly when edit is completed.

I tried to set the Column Width to Auto, in the GridView and individually in each column, but the calculation for optimal width seems to be chaotic and triggered but some other actions on the GridView.

Is there a way in code behind to iterate through each column and trigger a width calculation?

 

Thank you for your help

Hello Romain,

The desired behavior (of the column resizing when it is edited and resizing back when the edit ends) should be the default for the control. I tested this scenario in a sample project, where I defined a CellEditTemplate with a larger Width and on my end the column is resized as expected. 

I am attaching the sample project, which I used for testing purposes. Can you check it out and see how it differs from the setup on your end? Should you need any further assistance, you can modify the provided project in order to demonstrate the scenario and send it back. This will hopefully allow me to investigate further and better assist you. 

Thank you in advance for any help you can provide.

I agreed with you, in most case it works pretty good... But in my case, I have more a more complex implementation with template selectors, style selectors, and validations.

Unfortunately, it would be way too time consuming to recreate an example project that reflects my projects and its architecture.

My original question is: is there a way, in code behind, to go through each columns and force it to re-calculate it's size ? There is something for WinForms libraries and so, I was hoping to find a solution for WPF

 

Thank you

What comes to mind in order to force the columns to update is to set their Width to a fixed size and then set it back to Auto. Here is how that might look:

foreach (var c in this.gridView.Columns)
{
                c.Width = new GridViewLength(100, Telerik.Windows.Controls.GridViewLengthUnitType.Pixel);
                c.Width = GridViewLength.Auto;
}

Do give this a try and let me know, if it helps.
