How to hide cell contents?

[Konstantin Babiy]

Hello everybody

I have next issue in gridGroupingControl:
When starting editing of a cell (from ONE specific column), I need to hide cell contents and only show user what he enterred, and then (when value entering is finished) append enterred value to previous value and show it all.

I tried to do it through operations with a datasource, but met a problem that setting any value to a datasource makes focus leaving cell and accepting enterred data.

Thanks for your help!

Hi Konstantin,

You can handle the TableControlCurrentCellStartEditing to get the Old text before editing the cell and handle the TableControlCurrentCellEditingCompleteto to set the combined text to the cell. Below is a code snippet.

string currentValue = string.Empty;

private void TableControlCurrentCellStartEditing(object sender, GridTableControlCancelEventArgs e)
{
GridCurrentCell cc = e.TableControl.CurrentCell;
currentValue = e.TableControl.Model[cc.RowIndex,cc.ColIndex].Text;
cc.Renderer.ControlText = string.Empty;
}

private void TableControlCurrentCellEditingComplete(object sender, GridTableControlEventArgs e)
{
GridCurrentCell cc = e.TableControl.CurrentCell;
e.TableControl.Model[cc.RowIndex,cc.ColIndex].Text = currentValue + e.TableControl.Model[cc.RowIndex,cc.ColIndex].Text;
}

Let me know if this helps.
Best Regards,
