Error in new version Resize column programmatically

[Cesar]

Hi;

I found a problem in the resizing of columns when using customized groups. This error did not occur with the previous version (Q2) and has appeared in the current version (Q3).

I attached two files with the same project using the two versions. In the previous version columns are resized correctly and present it does not​. As soon as you remove your answer and projects which included two versions of DLLs that ye be easier to prove:

https://dl.dropboxusercontent.com/u/21787064/GridView_Q3.rar​​

Is it possible I'm doing something wrong?

I regard as a very serious mistake and I can not update my applications to version Q3 until it is solved.

Hello Cesar,

Thank you for writing.

I have logged it in our feedback portal. You can track its progress, subscribe for status changes and add your vote/comment to it on the following link - feedback item.

I have also updated your Telerik points.

Currently, the possible solution that I can suggest is either set the columns width before setting the RadGridView.ViewDefinition or call the TableElement.ViewElement.RowLayout.InvalidateRenderColumns method after specifying the width:

for (int i = 0; i < 5; i++)
{
    this.radGridView1.Columns.Add("Col" + i);
}

ColumnGroupsViewDefinition columnGroupsView = new ColumnGroupsViewDefinition();
columnGroupsView.ColumnGroups.Add(new GridViewColumnGroup());
columnGroupsView.ColumnGroups.Add(new GridViewColumnGroup());
columnGroupsView.ColumnGroups.Add(new GridViewColumnGroup());
columnGroupsView.ColumnGroups.Add(new GridViewColumnGroup());

columnGroupsView.ColumnGroups[0].PinPosition = PinnedColumnPosition.Left;
columnGroupsView.ColumnGroups[0].Rows.Add(new GridViewColumnGroupRow());
columnGroupsView.ColumnGroups[0].Rows[0].ColumnNames.Add("Col3");
this.radGridView1.Columns["Col3"].PinPosition = PinnedColumnPosition.Left;

columnGroupsView.ColumnGroups[1].Rows.Add(new GridViewColumnGroupRow());
columnGroupsView.ColumnGroups[1].Rows[0].ColumnNames.Add("Col2");
columnGroupsView.ColumnGroups[2].Rows.Add(new GridViewColumnGroupRow());
columnGroupsView.ColumnGroups[2].Rows.Add(new GridViewColumnGroupRow());
columnGroupsView.ColumnGroups[2].Rows[0].ColumnNames.Add("Col0");
columnGroupsView.ColumnGroups[2].Rows[1].ColumnNames.Add("Col1");

columnGroupsView.ColumnGroups[3].Rows.Add(new GridViewColumnGroupRow());
columnGroupsView.ColumnGroups[3].PinPosition = PinnedColumnPosition.Right;
columnGroupsView.ColumnGroups[3].Rows[0].ColumnNames.Add("Col4");
this.radGridView1.Columns["Col4"].PinPosition = PinnedColumnPosition.Right;

this.radGridView1.ViewDefinition = columnGroupsView;

this.radGridView1.Columns["Col2"].Width = 150;
this.radGridView1.Columns["Col0"].Width = 200;
this.radGridView1.TableElement.ViewElement.RowLayout.InvalidateRenderColumns();

 

I hope this information helps. Should you have further questions I would be glad to help.

Thank you for your answer, that option I can be used to solve the problem.

Now I find another mistake, if we group the head of the columns of the pinned cells, the ShowHeader utilizarñíamos property. If we use your code:

InitializeComponent();

            ColumnGroupsViewDefinition columnGroupsView;

            // column groups view
            columnGroupsView = new ColumnGroupsViewDefinition();
            columnGroupsView.ColumnGroups.Add(new GridViewColumnGroup());
            columnGroupsView.ColumnGroups.Add(new GridViewColumnGroup());
            columnGroupsView.ColumnGroups.Add(new GridViewColumnGroup());
            columnGroupsView.ColumnGroups.Add(new GridViewColumnGroup());

            columnGroupsView.ColumnGroups[0].Rows.Add(new GridViewColumnGroupRow());
            columnGroupsView.ColumnGroups[0].ShowHeader = false;
            columnGroupsView.ColumnGroups[0].PinPosition = PinnedColumnPosition.Left;
            columnGroupsView.ColumnGroups[0].Rows[0].ColumnNames.Add("colPINNED_LEFT");
            this.radGridView1.Columns["colPINNED_LEFT"].PinPosition = PinnedColumnPosition.Left;


            columnGroupsView.ColumnGroups[1].Rows.Add(new GridViewColumnGroupRow());
            columnGroupsView.ColumnGroups[1].ShowHeader = false;
            columnGroupsView.ColumnGroups[1].Rows[0].ColumnNames.Add("colDATE");

            columnGroupsView.ColumnGroups[2].Rows.Add(new GridViewColumnGroupRow());
            columnGroupsView.ColumnGroups[2].Rows.Add(new GridViewColumnGroupRow());
            columnGroupsView.ColumnGroups[2].ShowHeader = false;
            columnGroupsView.ColumnGroups[2].Rows[0].ColumnNames.Add("colTITLE");
            columnGroupsView.ColumnGroups[2].Rows[1].ColumnNames.Add("colTEXT");

            columnGroupsView.ColumnGroups[3].Rows.Add(new GridViewColumnGroupRow());
            columnGroupsView.ColumnGroups[3].ShowHeader = false;
            columnGroupsView.ColumnGroups[3].PinPosition = PinnedColumnPosition.Right;
            columnGroupsView.ColumnGroups[3].Rows[0].ColumnNames.Add("colPINNED_RIGHT");
            this.radGridView1.Columns["colPINNED_RIGHT"].PinPosition = PinnedColumnPosition.Right;



            this.radGridView1.ViewDefinition = columnGroupsView;

            this.radGridView1.Columns["colDATE"].Width = 110;
            this.radGridView1.Columns["colTITLE"].Width = this.radGridView1.Width - 181;

            this.radGridView1.TableElement.ViewElement.RowLayout.InvalidateRenderColumns();

If we use the Q2 version works perfectly but when you upgrade to version Q3 fails.

Thanks again and I hope we can resolve errors quickly, I can not upgrade to the new version if these serious errors are not corrected.

Hello Cesar,

Thank you for writing back.

I confirm that when setting the GridViewColumnGroup.ShowHeader property to false for a pinned group leads to layout. I have logged it in our feedback portal. You can track its progress, subscribe for status changes and add your vote/comment to it on the following link - feedback item.

I have also updated your Telerik points.

Currently, the possible solution that I can suggest is instead of setting the ShowHeader property to false use the ViewCellFormatting event to hide to necessary cell borders and customize the text alignment to simulate cells merging.

I hope this information helps. If you have any additional questions, please let me know.

Thank you for your answer again.

This type of group I have many sites included in my application and takes too much having to use the event at all.

I prefer to wait until you update the controls to change the version Q3.
