[Solved] Customized controls embedded in GridView

[Blue Chen]

I try to embed RadCheckBoxElement to GridView in CellFormating event. My scenario is to show a RadCheckBoxElement in row "caption0". My Telerik controls version is Q1 2010.

       void radGridView1_CellFormatting(object sender, CellFormattingEventArgs e)
        {
            if (e.CellElement.ColumnInfo is GridViewDataColumn && ((GridViewDataColumn)e.CellElement.ColumnInfo).FieldName == "Caption")
            {
                if (!(e.CellElement.RowElement is GridTableHeaderRowElement))
                {
                    if (e.CellElement.Text.Equals("caption0"))
                    {
                        if (e.CellElement.RowInfo.Cells["Value"].CellElement.Children.Count > 0)
                            return;
                        RadCheckBoxElement element = new RadCheckBoxElement();
                        e.CellElement.RowInfo.Cells["Value"].CellElement.Children.Add(element);
                    }
                }
            }
        }

It seems that everything works fine without scrollbar.

However, if I scroll the scrollbar, a strange issue will happen. The RadCheckBoxElement will be embedded not only in row "caption0" but also in other rows. If I scroll the scrollbar several times, more and more RadCheckBoxElement will be shown in different rows.

Please refer to the attached images.

Could anybody help me? Thank you.

Hi Blue Chen,

Your scenario requires the creation of custom data cell, because in CellFormatting you cannot arrange the content of the cell. You can read more about that in this documentation article which describes similar cases but with several radio buttons.

If you need further assistance feel free to contact us back.

Hi Adolfo,

We always update our online documentation and knowledge base articles to be relevant with the latest version. I recommend downloading and upgrading to the latest version Q2 2010 v713, where many issues have been addressed. You can read more about the new features and resolved issues in the latest release notes.

As to the cell formatting event for your version (Q2 2009 SP1), please review the relevant help topic in the documentation which is installed with your particular version on your machine.

 
Sincerely yours,
