GridGroupingControl - Selected records not cleared first time

[Badri Rajani Kanth]

Dear Syncfusion,

We are using V 4.2.0.37.

gridgroupingControl.Table.SelectedRecords.Clear(); is not clearing the records for the first time. It is only clearing second time. I tried even using gridgroupingControl.Refresh().

What else should we do? Can you plz inform.

Hi Rajani,

I was not able to reprodue this problem here, please see the attached sample that works fine in selected record clear method in the grid.

Here is a sample.

If this did not help, please update us with a sample project showing the problem.

Thanks,

Hi Haneef,

I am not able to download the zip file on your link.

Ok, my form is having a GGC. These are my grid settings

private void FormatGrid()
{
GGC.TableOptions.AllowSelection = Syncfusion.Windows.Forms.Grid.GridSelectionFlags.None;
GGC.TableOptions.ListBoxSelectionCurrentCellOptions =
Syncfusion.Windows.Forms.Grid.Grouping.GridListBoxSelectionCurrentCellOptions.None;
GGC.TableOptions.ListBoxSelectionMode = System.Windows.Forms.SelectionMode.One;
GGC.TableModel.Options.ShowCurrentCellBorderBehavior =
GridShowCurrentCellBorder.HideAlways;
GGC.TableModel.Options.SelectCellsMouseButtonsMask =
System.Windows.Forms.MouseButtons.Left | System.Windows.Forms.MouseButtons.Right;
GGC.TableControl.HScrollBehavior = GridScrollbarMode.Disabled;
GGC.TableOptions.IndentWidth = 0;
GGC.TableOptions.ShowRowHeader = false;
GGC.TableOptions.CaptionRowHeight = 0;

}

And grid displays few records. When I right click on column headers, i want to clear the record selection. Here is the code for that, which is not clearing for the first time.

private void GGC_TableControlMouseDown(object sender, Syncfusion.Windows.Forms.Grid.Grouping.GridTableControlMouseEventArgs e)
{
int rowIndex = 0;
int colIndex = 0;

bool clickedInsideGrid =
e.TableControl.PointToRowCol(new System.Drawing.Point(e.Inner.X, e.Inner.Y), out rowIndex, out colIndex);
//clicked inside grid?
if(clickedInsideGrid)
{
if(e.Inner.Button == MouseButtons.Right)
{
if(rowIndex == COLUMN_HEADER_ROW_INDEX) //COLUMN_HEADER_ROW_INDEX = 1
{
//clear record selection and contexts
GGC.Table.SelectedRecords.Clear();
return;
}

}
}
}

Hi Rajani,

To get the desired behavior, add the code below in the TableControlMouseDown event handler of the GridGroupingControl.

private void gridGroupingControl1_TableControlMouseDown(object sender, GridTableControlMouseEventArgs e)
{
    Point pt = new Point(e.Inner.X, e.Inner.Y);
    GridTableCellStyleInfo style = this.gridGroupingControl1.TableControl.PointToTableCellStyle(pt);
    if(style.TableCellIdentity.TableCellType == GridTableCellType.ColumnHeaderCell)
    {
        this.gridGroupingControl1.Table.SelectedRecords.Clear();
    }
}

Thanks for using Syncfusion Products.

Thank You Raja Gopal,

Problem is not with identifying ColumnHeaderCell.

SelectedRecords.Clear() is not clearing the very first time.

Hi Rajani,

We tried to reproduce this issue in 4.1/ 4.2.0.37 with .Net 2003+Windows XP sp2, but could not get this issue. Maybe I am not following the steps that you are doing. Attached sample working fine here. Can you post a small sample showing this problem or tell us how to see it in the Attached sample?

Sample : http://www.syncfusion.com/Support/user/uploads/ClearRecordGGC_317cca61.zip

Please let me know the version number of Studio you are testing this with and the .Net version.

Thanks,
Haneef
