GridComboBoxColumn search problem

[Ruben]

Hi,

I have a question, i have these code

new GridComboBoxColumn()

                    {

                        MappingName = "IdTercero",

                        HeaderText = "Tercero",

                        DataSource = l_terceros,

                        ValueMember = "Id",

                        DisplayMember = "Tercero",

                        ValidationMode = GridValidationMode.InEdit,

                        DropDownStyle = DropDownStyle.DropDown,

                        AutoCompleteMode = AutoCompleteMode.Suggest,

                        AutoSuggestMode = AutoCompleteSuggestMode.Contains,

                        AutoSuggestDelay = 300,

}

l_terceros is a list, the search works fine but if i search (xdasjdlasjdlasjdals) the combox show all results, it´s posible not show any information?

Thanks.

Hi Ruben, 

Thanks for contacting Syncfusion support.  

We have checked the reported scenario in GridComboBoxColumn. We have used our SfComboBox as the edit element in the GridComboBoxColumn and the reported scenario is the behavior of SfComboBox. We have forwarded this query to the corresponding. We will update with further details on 10^th November 2020. We appreciate your patience until then.

Hi Ruben, 

Thanks for your patience.  

Your requirement can be achieved by creating a custom render for the GridComboBoxColumn as shown in the following code example.  

Code example :  

this.sfDataGrid.CellRenderers["ComboBox"] = new CustomComboBoxCellRenderer(); 

 

 

public class CustomComboBoxCellRenderer : GridComboBoxCellRenderer 

{ 

    SfComboBox comboBox = null; 

    protected override void OnInitializeEditElement(DataColumnBase column, RowColumnIndex rowColumnIndex, SfComboBox uiElement) 

    { 

        comboBox = uiElement; 

        uiElement.TextBox.TextChanged += UiElement_TextChanged; 

 

        base.OnInitializeEditElement(column, rowColumnIndex, uiElement); 

 

    } 

 

    private void UiElement_TextChanged(object sender, System.EventArgs e) 

    { 

        if (comboBox != null) 

        { 

            comboBox.DropDownListView.View.Filter = FilterItem; 

            comboBox.DropDownListView.View.RefreshFilter(); 

        } 

    } 

 

    private bool FilterItem(object obj) 

    { 

        if (obj.ToString().ToLower().Contains(comboBox.TextBox.Text)) 

            return true; 

        return false; 

    } 

} 

We have prepared a sample using the above given code example and it is available in the following link for your reference.
