I’m trying to disable the mouse wheel event when the focus is within a combo box in an UltraGrid.
I can disable the scrolling for the entire grid, which is not what I want, but I cannot figure out how to do it for that specific combo. I can get the column, but UltraGridColumn does not have an event for OnMouseWheel where I can absorb the handler. Any ideas?
If you change the Combo Box Style to something else could that stop the scrolling? I know there are a few styles where you can disable AutoComplete and Typing forcing the user to click the drop-down.
I got it after all. I spend hours on something to no avail, but then the moment I ask, I find a solution.

Thank you i made it for Erp.UI.Controls.Combos:
EpiCombo cboBuyer;
public void InitializeCustomCode()
{
// ** Wizard Insert Location - Do not delete 'Begin/End Wizard Added Variable Initialization' lines **
// Begin Wizard Added Variable Initialization
this.baseToolbarsManager.ToolClick += new Infragistics.Win.UltraWinToolbars.ToolClickEventHandler(this.baseToolbarsManager_ToolClick);
// End Wizard Added Variable Initialization
// Begin Wizard Added Custom Method Calls
session= (Session)this.oTrans.Session;
// End Wizard Added Custom Method Calls cmbBuyer
grdList=((EpiUltraGrid)csm.GetNativeControlReference("4d59326f-7a76-4c5c-8e2c-54e630db64da"));
grdSubcontract = ((EpiUltraGrid)csm.GetNativeControlReference("fcef0a0c-90f6-48b5-8133-f892a2515b84"));
cboBuyer = ((EpiCombo)csm.GetNativeControlReference("b734a402-4630-4190-b273-f51cd5f95b37"));
grdSubcontract.DisplayLayout.Bands[0].Columns["BuyerID"].ValueList =cboBuyer;
EpiDataView edvCallContextBpmData = ((EpiDataView)(this.oTrans.EpiDataViews["CallContextBpmData"]));
System.Data.DataRow edvCallContextBpmDataRow = edvCallContextBpmData.CurrentDataRow;
if ((edvCallContextBpmDataRow != null))
{
try{
edvCallContextBpmDataRow.BeginEdit();
edvCallContextBpmDataRow["CheckBox06"] =false;
edvCallContextBpmDataRow.EndEdit();
}
catch{}
}
cboBuyer.MouseWheel += new MouseEventHandler(cboBuyer_MouseWheel);
}
public void DestroyCustomCode()
{
// ** Wizard Insert Location - Do not delete 'Begin/End Wizard Added Object Disposal' lines **
// Begin Wizard Added Object Disposal
this.baseToolbarsManager.ToolClick -= new Infragistics.Win.UltraWinToolbars.ToolClickEventHandler(this.baseToolbarsManager_ToolClick);
cboBuyer.MouseWheel -= new MouseEventHandler(cboBuyer_MouseWheel);
// End Wizard Added Object Disposal
// Begin Custom Code Disposal
// End Custom Code Disposal
}
void cboBuyer_MouseWheel(object sender, MouseEventArgs e)
{
HandledMouseEventArgs args = e as HandledMouseEventArgs;
if (args != null)
args.Handled = true;
}
But for Ice.Lib.Framework.EpiUltraCombo it’s easier:
Just change the DropDownStyle
private void MainController_Load(object sender, EventArgs args)
{
// Add Event Handler Code
//khởi tạo các biến cục bộ
tblSubModule = new DataTable();
session=this.oTrans.Session as Ice.Core.Session;
epiCheckBoxC_Overwrite.Text = "Overwrite";
epiButtonC_Sync.ReadOnly = true;//khóa nút đồng bộ
this.baseToolbarsManager.Tools["RefreshTool"].SharedProps.Enabled = false;//khóa nút Refresh
this.epiUltraComboC_Module.DropDownStyle = UltraComboStyle.DropDownList;//không cho nhập text
this.epiUltraComboC_Module.Rows[0].Selected = true;
this.epiComboC_Company.DropDownStyle = UltraComboStyle.DropDownList;//không cho nhập text
SearchOnCompanyAdapterFillDropDown();
this.epiComboC_Company.Value = session.CompanyID;
//this.epiComboC_Company.Value = session.CompanyID;
this.epiComboC_Company.ReadOnly = true;//khóa không cho chọn công ty
//
//epiTextBoxC_Object2.ReadOnly = true;
//epiTextBoxC_Object2.Clear();
epiUltraComboC_TranType.ReadOnly = true;
this.epiUltraComboC_TranType.Rows[0].Selected = true;
this.epiUltraComboC_TranType.DropDownStyle = UltraComboStyle.DropDownList;//không cho nhập text
}
Thank you so much have a nice day!
