Hi,
I have a value fetching from database like;

Purushottam Kumar(12478,OC)

 
where I want to show only Purushottam Kumar as display value in the single cell of WinRadGidView and the complete values Purushottam Kumar(12478,OC) or rest of values (12478,OC) should be also available in hidden form in the same cell.

Please help me how I can maintain  the both display value and hidden value in the same cell simulteneously.

Regards,
Purushottam Kumar

Hi Purushottam,

We are not sure that the grid control should split your data in such way. Anyway, this is the work-around I can think of, however we will suggest rethinking the logic of your application:

private void Form1_Load(object sender, EventArgs e) 
        { 
            DataTable t = new DataTable(); 
            t.Columns.Add("A"); 
            t.Rows.Add("Purushottam Kumar(12478,OC)"); 
            t.Rows.Add("Purushottam Kumar(12478,OC)"); 
 
            this.radGridView1.DataSource = t; 
 
             
        } 
 
        private void radGridView1_CellFormatting(object sender, Telerik.WinControls.UI.CellFormattingEventArgs e) 
        { 
            if (e.CellElement.ColumnInfo.HeaderText == "A"
            { 
                e.CellElement.Text = e.CellElement.RowInfo.Cells["A"].Value.ToString().Substring(0, 17); 
            } 
        } 

Please note that you can use more complicated code in CellFormatting event handler to find the substring you need.

If the column is read-only the above should work properly, however if you need to edit your cells you need to implement further workarounds. You may try to subscribe to CellBeginEdit and CellEndEdit events:

string realValue; 
        private void radGridView1_CellBeginEdit(object sender, Telerik.WinControls.UI.GridViewCellCancelEventArgs e) 
        { 
            realValue = this.radGridView1.ActiveEditor.Value.ToString(); 
            //change value so that the end of the string is not shown
        } 
 
        private void radGridView1_CellEndEdit(object sender, Telerik.WinControls.UI.GridViewCellEventArgs e) 
        { 
            //append the end of your string  
        } 


All the best,
