changing available values in combobox column for a selected row in the GGC

[Brian Corley]

I am using the GGC and have a combobox style column. The values are not the same for every given row in the grid. I need the ability to change the values in the datasource the combobox column is bound to as the user selects new rows.

You can try using TableControlCurrentCellShowingDropDown to dynamically set the datasource of the dropdown. Here is a forum thread discussing this issue.

I now have this working (kind of).

in the grid_TableControlCurrentCellCloseDropDown method I am setting the value on my internal object but until I actually click off the row or select a new row, I don''t see the new value. Is there a way I can force the cell to update the text from the newly selected drop down value when grid_TableControlCurrentCellCloseDropDown is called?

here is what I am doing:

private void grid_TableControlCurrentCellCloseDropDown(object sender, Syncfusion.Windows.Forms.Grid.Grouping.GridTableControlPopupClosedEventArgs e)
{
try
{
GridCurrentCell cc = e.TableControl.CurrentCell;

if(cc.Renderer is GridComboBoxCellRenderer)
{
//get the list of brokers for this market
MarketW mw = (MarketW)currentRec.GetData();
brokers = proc.GetBrokersForLocation(this.sub,mw.GetInternalMarket().Location);
GridComboBoxCellRenderer cr = cc.Renderer as GridComboBoxCellRenderer;

foreach(People p in brokers)
{
if(p.PeopleSkey == int.Parse(cr.ControlValue.ToString()))
{
mw.GetInternalMarket().People = p;
cc.EndEdit();
break;
}
}
}
}
catch{}
}

Figured it out:

private void grid_TableControlCurrentCellCloseDropDown(object sender, Syncfusion.Windows.Forms.Grid.Grouping.GridTableControlPopupClosedEventArgs e)
{
try
{
GridCurrentCell cc = e.TableControl.CurrentCell;

if(cc.Renderer is GridComboBoxCellRenderer)
{
//get the list of brokers for this market
MarketW mw = (MarketW)currentRec.GetData();
brokers = proc.GetBrokersForLocation(this.sub,mw.GetInternalMarket().Location);
GridComboBoxCellRenderer cr = cc.Renderer as GridComboBoxCellRenderer;

foreach(People p in brokers)
{
if(p.PeopleSkey == int.Parse(cr.ControlValue.ToString()))
{
mw.GetInternalMarket().People = p;
cc.EndEdit();
cc.Refresh();
break;
}
}
}
}
catch{}
}
