Coverage

[leemarose]

Hi all,

I got the problem in the syncfusion gird
when i include this line..

this.Bidsheet.Model.CoveredRanges.Add(GridRangeInfo.Cells(FromRow,1,ToRow,1));

to combine Rows.

Its Combine Rows well but the problem is the loading process taking so long time.

its 5 to 10 times slower when i excluded that line.

Give me suggestion to speed up the process.

thanks in advance.

Hi Leema,

Can you try this way and see if there is improvement in the performance.

this.gridControl1.BeginUpdate();
//
// Code to CoverRange
this.Bidsheet.Model.CoveredRanges.SetCoveredRange(GridRangeInfo.Cells(FromRow,1,ToRow,1),true);
//
this.gridControl1.EndUpdate();

Best Regards,

Hi hannef!

Another problem in my grid with coverrange is that-

When i delete a set of records with one checkbox(these records are covered through coverrange).the whole gird collape with coverage range overlapping on each other.

but when i close the form and open again,it displays in proper format and cover range is exact in the grid.

why this happening,i used grid.refesh() method but nothing worked out.

any other way pls suggest.

Hi Leema,

The reason for collaping the Grid in your case is that the Model.CoveredRange collection is not resetted properly. Befor deleting the set of records, you should remove the proper covered range by using the FindRange method. Here is a code snippet

this.gridControl1.Model.Rows.RemoveRange(1,1);
//Find the Range..
GridRangeInfo range = this.gridControl1.Model.CoveredRanges.FindRange(1,2);
//Remove the proper covered range
this.gridControl1.Model.CoveredRanges.Remove(range);
//add the new Range
this.gridControl1.Model.CoveredRanges.Add(range);

Hi haneef;

I have to delete records from Row 1 to 7.
These Rows comes under one Coverage area.
so, as per ur coding i gave..

this.dgTransactionList.Model.Rows.RemoveRange
(1,7);
//I can specify only starting row and Ending Row

but in this line how can i specify Rowindex and Colindex for getting range..
GridRangeInfo range = this.dgTransactionList.Model.CoveredRanges.
FindRange(rowindex,Columnindex).

Another thing i dont want to create new range.

just I want delete the set of records
belonging to one coverage.once deleted,the coverage area belong the one deleted should occupy its place without collapsing and coverage area of the records should be displayed in the grid quite neatly.

Can u suggest me a solution for my problem.
