Reg: GridDataBoundControl

[Anna Srinivasan]

Hi,
I am using griddataBound Control.
For validation (double) i am using CurrentCellValidateString event.

Note : DB Column allows null values.

Error msg i am capturing in ValidateFailed event.(Actually i dont want error msg)
this.sgbDetailedHistory.CurrentCell.ErrorMessage = ""; (Blank)

All above working fine.But i am facing problem.

Scenorio:
1) Enter double value in the grid cell.
2) Delete the value.
3) Try to move to other cell.
I am not able to move to other cell. I have to fill some value then only i can able to move.

How do i handle this scenorio..?

Does the code in your CurrentCellValidateString allow empty strings to be processed without setting e.Cancel = true?

If you set e.Cancel=true, either in CurrentCellValidateString or in CurrentCellValidating, when the string is empty, then that is why your user cannot leave such a cell. You should not set e.Cancel = true in this case.

I do not have any special handlers. Here is project. Try to add some records in the grid, you will see empty lines in output. Doesn''t matter release or debug configuration. WindowsApplication37_8603.zip

Please go through the following code ..

private void sgbDetailedHistory_CurrentCellValidateString(object sender, Syncfusion.Windows.Forms.Grid.GridCurrentCellValidateStringEventArgs e) {
try {
GridCurrentCell cc = this.sgbDetailedHistory.CurrentCell;
string newValue = e.Text;
if(cc.ColIndex >= 2 && cc.ColIndex <= 6) {
double d;
if (newValue.Trim() != "") {
if(!double.TryParse(newValue, System.Globalization.NumberStyles.Any, null, out d)) {
}
}
}
} catch (Exception ex) {
Logger.WriteLogEntry("Error in DateTime Convertion", ex, LogType.Error);
}
}

private void sgbDetailedHistory_ValidateFailed(object sender, Syncfusion.Windows.Forms.Grid.GridValidateFailedEventArgs e) {
this.sgbDetailedHistory.CurrentCell.ErrorMessage = "";
}

I am not using any other event.

What version of our libraries are you using? In earlier versions, you could not leave a double column with it containing an empty string. But you can in the more recent releases.

[Anna Srinivasan]

Right now we are using 3.2.1.0 version.
It is not possible in this version.

No, this should work in 3.2.1.0. Here is a sample showing youable to delete the number in the first column and move off the cell. How do I see teh problem in this sample?
