Make the Grid inactive except the current row.

[ngp]

Haneef,

I have a grid where I can add a new row on a button click.

1. I need to set the new row added as the Active/Current/Selected/pointed Row
2. I need the rest of the rows to be disabled. and the textcolor = SystemColors.InactiveCaptionText

It would be great if you could provide a small code snippet to do the same.

Thanks a lot.
Grace

Hi Grace,

Thanks for your interest in Syncfusion Products.

1. To set the new row added as the active current row, try the code below in your button click handler.

int lastAddedRecord = this.gridGroupingControl1.Table.Records.Count-1;
this.gridGroupingControl1.Table.Records[lastAddedRecord].SetCurrent();

2. To disable all the rows except the current row, please try the code below in the QueryCellStyleInfo event of the GridGroupingControl.

void gridGroupingControl1_QueryCellStyleInfo(object sender, GridTableCellStyleInfoEventArgs e)
{
    Element el = e.TableCellIdentity.DisplayElement;
    if (el.Kind == DisplayElementKind.Record)
    {
        Record rec = el.GetRecord();
        if (e.TableCellIdentity.ColIndex > 0 && e.TableCellIdentity.Table.CurrentRecord != rec)
        {
            e.Style.TextColor = SystemColors.InactiveCaptionText;
            e.Style.CellType = "Static";
        }
    }
}

Please try the above code and let me know if this helps.

Have a nice time.

Hi Grace,

If you are using Arraylist as the datasource for the grid, then grid does not respond to changes in the data source, the data source has to implement the IBindingList interface. DataTable does this, but ArrayList does not. But you can derive an ArrayList so it does implement IBindingList. If you do this, then the grid should display the changes as they are made to the arraylist.

Please refer the sample below that meets your requirements

Let me know if you have any other questions.
