How to hide columns in GridListControl

[Ruslan Gasanbekov]

Hi,

I got GridListControl which placed inside GridGroupingControl.
I bind the grid with DataSource as followed:

private void gridGrpCtrlAssignEmps_TableControlCurrentCellActivated(object sender, GridTableControlEventArgs e)
{
GridDropDownGridListControlCellRenderer dropDownRenderer = cc.Renderer as GridDropDownGridListControlCellRenderer;

if (dropDownRenderer != null)
{
if (column.Name == this.m_Dictionary["SignIn"])
{
GridListControl listControlSignIn = dropDownRenderer.ListControlPart;
listControlSignIn.DataSource = this.getClockSignList(clockSignList, "SignIn");
listControlSignIn.DisplayMember = this.m_Dictionary["SignIn"];
listControlSignIn.ValueMember = this.m_Dictionary["SignIn"];

listControlSignIn.Click += new EventHandler(listControlSignIn_Click);
}}

I would like to hide some of the binded columns when the drop down is opened.
How can it be achived?

Hi Ruslan,

Thanks for your interest in Syncfusion Products.

To hide some of the columns in the dropdownlist while showing, you can make use of the HideCols of the Grid through the ListControlPart object. Here is the code that can be handled in TableControlCurrentCellActivated event for your reference.

GridCurrentCell cc = e.TableControl.CurrentCell;
GridDropDownGridListControlCellRenderer rend = cc.Renderer as GridDropDownGridListControlCellRenderer;
GridDropDownGridListControlPart part = rend.ListControlPart as GridDropDownGridListControlPart;
part.DataSource = listTable();
part.DisplayMember = "State";
part.ValueMember = "City";
part.Grid.HideCols[3] = true;  //code used to hide certain column in dropdownlist
