Hi,

I need to run BestFitColumns on a hierarchical grid.

The master view template works fine, but I can't seem to get it to work with the child columns.

I am doing the following:

someGrid.MasterGridViewTemplate.ChildGridViewTemplates[0].BestFitColumns();

Thanks

Hi Jorge Delgado-Lopez,

Thank you for writing. Although we have BestFitColumns method in every grid template, currently we do not support best fit in child views. We will include this feature in some of the next releases. I have updated your Telerik points for bringing our attention to this matter. Do not hesitate to contact me again if you have other questions.

Hi,

I need also this functionnality. I noticed that when one doubleclik betwen two child view columns the left one does fit. However, after the ChildViewExpanded event is fired, calling BestFit() does not work. How to programmatically call the same function that produces the column fit when doubleclicked on the border ?

this does not work :

    
            protected override void OnChildViewExpanded(object sender, ChildViewExpandedEventArgs e){  
        
            base.OnChildViewExpanded(sender, e);  
        
            foreach(GridViewDataColumn column in e.ChildViewInfo.ViewTemplate.Columns)  
        
            column.BestFit();  
        
            }

Hi jpl,

Thank you for contacting us. Unfortunately, there is no way to use double click AutoSize functionality using code. Please, excuse us for the inconvenience.

Sincerely yours,

Hello Oleg,

Thank you for writing.

You can best fit the columns in child templates by using the ChildViewExpanded event handler:

void radGridView1_ChildViewExpanded(object sender, ChildViewExpandedEventArgs e)

{

e.ChildViewInfo.ViewTemplate.BestFitColumns();

}

I hope this helps.

Stefan

I am using UI for WinForms version 2014.1 226

Using the suggested logic still cannot bestfit child template in hierarchical grid.

Is this fixed in new releases?

Hello Freddie,

The provided approach in my previous post works correctly on my end with both the latest version and the version you mentioned. If you still experience issues, I would suggest opening a support ticket where you can attach the problematic project and we will gladly look into it.

This is also not working for me. has anything changed or is it still supposed to work this way?

Also, I am trying to add filtering and excel filtering. I added the following:

e.ChildViewInfo.ViewTemplate.ShowFilterCellOperatorText = False
e.ChildViewInfo.ViewTemplate.ShowHeaderCellButtons = True

is this correct in the child expanded event to work?

thanks

This seems to be working fine for me with the first ChildView, but not any additional ones.

Hi Aaron,

Thank you for writing back.

The ChildViewInfo received as an event argument is the active view of the template and it successfully best fits its columns. I am assuming that you are having multiple views on one level.

In a scenario in which there are more than one views you can best fit them this way:

private void radGridView1_ChildViewExpanded(object sender, ChildViewExpandedEventArgs e)

{

GridViewHierarchyRowInfo parent = e.ParentRow as GridViewHierarchyRowInfo;

if (parent != null)

{

foreach (GridViewInfo view in parent.Views)

{

view.ViewTemplate.BestFitColumns();

}

Abba, perhaps you are having the same scenario. Can you try accessing the views as per my suggestion above? Please also do not forget to set the EnableFiltering property of your templates to true.

Alternatively, you can always access the view templates while you are creating them or at a later stage: Accessing Child Templates. I am also attaching a short video showing the result on my end.

I hope this helps. Should you have further questions please do not hesitate to write back.

Hi Hristo,

Thanks so much for that snippet! I had a feeling it was something along those lines, but poking around through Object Explorer and Intellisense, I had been unable to find the proper properties to get to that child view collection.

This worked perfectly!

Cheers!
