How to validate webcombo for requiredfield validator [not custom validator]

Kamran posted over 16 years ago

I have read http://www.componentsource.com/products/webcombo-net/summary.html that webcombo can be validated via requiredfield validator.

But when i use

<igcmbo:WebCombo ID="cboTransmission" runat="server" BackColor="White" BorderColor="Silver"
                                                    BorderStyle="Solid" BorderWidth="1px" ForeColor="Black" SelBackColor="DarkBlue"
                                                    SelForeColor="White" Version="4.00" Width="77px" OnInitializeLayout="cboTransmission_InitializeLayout">
                                                    <Columns>
                                                        <igtbl:UltraGridColumn>
                                                            <header caption="Column0"></header>
                                                        </igtbl:UltraGridColumn>
                                                    </Columns>
                                                    <ExpandEffects ShadowColor="LightGray" />
                                                    <DropDownLayout BorderCollapse="Separate" RowHeightDefault="20px" Version="4.00"
                                                        ColWidthDefault="" DropdownHeight="" DropdownWidth="">
                                                        <HeaderStyle BackColor="LightGray" BorderStyle="Solid">
                                                            <BorderDetails ColorLeft="White" ColorTop="White" WidthLeft="1px" WidthTop="1px" />
                                                        </HeaderStyle>
                                                        <FrameStyle BackColor="Silver" BorderStyle="Ridge" BorderWidth="2px" Cursor="Default"
                                                            Font-Names="Verdana" Font-Size="10pt">
                                                        </FrameStyle>
                                                        <RowStyle BackColor="White" BorderColor="Gray" BorderStyle="Solid" BorderWidth="1px">
                                                            <BorderDetails WidthLeft="0px" WidthTop="0px" />
                                                        </RowStyle>
                                                        <SelectedRowStyle BackColor="DarkBlue" ForeColor="White" />
                                                    </DropDownLayout>
                                                </igcmbo:WebCombo>
                                                    <asp:RequiredFieldValidator ID="cvTransmission" ControlToValidate="cboTransmission runat="server" InitialValue="" ErrorMessage="Transmission cannot be null." ValidationGroup="vgApp">*</asp:RequiredFieldValidator>

I got the error

Control 'cboTransmission' referenced by the ControlToValidate property of 'cvTransmission' cannot be validated.

I am using Infragistics2.WebUI.WebCombo.v7.2

I don't want's to use custom validator

What can I do ?

Use custom validator with this:

function ValidateCombo(oCombo,ColIndex) {
    try {

        var grid=oCombo.getGrid();
        var rowCount=grid.Rows.length;
        var currVal='';
        var comboText=oCombo.displayValue;

        for(i=0;i<rowCount;i++){
          var row=grid.Rows.getRow(i);
          currVal=row.getCell(ColIndex).getValue();
          if (currVal == comboText) {
            return true;
          }
        }
        return false;
    }
    catch ( err ) {
        var txtMessage = document.title + " - Error in ValidateCombo()\n" + err.description ;
        alert( txtMessage ) ;
    }

}

I think you might be using editable combo. even I am using that in my application. my requirement is I need to allow the user to create the new record and at the same user can select the existing one. I should raise error only if the displayvalue of the webcombo is null.we can't use required field validator for webcombo. I have used custom validator in that I have checked the displayvalue of the webcombo at the client side.

I hope this can help you...
function Validate(sender, args)
{
var combo = igcmbo_getComboById('<%=ddl.ClientID %>');if(combo.getValue() == null)
{

var str=combo.getDisplayValue();
if((str == null) || (str==""))
{

// alert(combo.getDisplayValue());
args.IsValid = false;
}

else
args.IsValid = true;
}

else

args.IsValid = true;
return args.IsValid;
}

<asp:CustomValidator ID="CVddlBusinessProces" runat="server" ErrorMessage="Please Select a Process or Enter the Name for Create"

Width="296px" ClientValidationFunction="ValidateBusinessProcess" ValidateEmptyText="True" ValidationGroup="BusinessProcessvalidation"></asp:CustomValidator>
