Hi Gregory, 
 
Greetings from Syncfusion. 
 
We have checked your query and we suspect that you need to filter the SFComboBox dropdown items based on the TextBox text changed. We have checked your textBox1_TextChanged method and added the condition to get the Names(SFComboBox Fliter item) based on the Id(TextBox.Text) and added the names to SFComboBox SelectedItems. 
 
 
 
Please try it with the provided solution and let us know if you need nay further assistance on this.

Elakkiya

Regards,

Gregory

Hi Gregory, 

Thanks for your update. 

We have checked your query and found that we can display the filtered items dynamically by adding the filterItems to checkedItem collection.  Please refer the sample for the same. 



Please try it with the above solution and let us know if you need any further assistance on this.

HI

how to add to gridGroupingControl sfComboBox1 and multiselectioncombobox just like this is done with GridListControl


   this.gridGroupingControl1.TableDescriptor.Columns[2].Appearance.AnyRecordFieldCell.CellType = GridCellTypeName.GridListControl;




SS Sampathnarayanan Sankaralingam Syncfusion Team January 21, 2022 12:02 PM UTC

Hi Gregory, 

You can achieve your requirement to set the SfComboBox and MultiSelection ComboBox to the CellType of GridGroupingControl using the below code snippet. 

SfComboBox sfComboBox = new SfComboBox(); 
List<string> country = new List<string>(); 
country.Add("India"); 
country.Add("Usa"); 
country.Add("Japan"); 
country.Add("China"); 
sfComboBox.DataSource = country; 
 
this.gridGroupingControl1.TableDescriptor.Columns[2].Appearance.AnyRecordFieldCell.CellType = GridCellTypeName.Control; 
this.gridGroupingControl1.TableDescriptor.Columns[2].Appearance.AnyRecordFieldCell.Control = sfComboBox; 
 
//MultiSelection Combox 
SfComboBox multiselectionComboBox = new SfComboBox(); 
List<string> states = new List<string>(); 
states.Add("Delhi"); 
states.Add("chennai"); 
states.Add("calfornia"); 
states.Add("newyork");  
states.Add("Beijing"); 
multiselectionComboBox.DataSource = states; 
multiselectionComboBox.ComboBoxMode = Syncfusion.WinForms.ListView.Enums.ComboBoxMode.MultiSelection; 
 
this.gridGroupingControl1.TableDescriptor.Columns[1].Appearance.AnyRecordFieldCell.CellType = GridCellTypeName.Control; 
this.gridGroupingControl1.TableDescriptor.Columns[1].Appearance.AnyRecordFieldCell.Control = multiselectionComboBox; 

Please let us know if you require further assistance from us.

Hi Gregory, 

Please find the response below.

it fills in other rows automatically and doesn't save to GGCds.Tables ["GGCDT"] 
You need to set the SfComboBox to the CellType of GridGroupingControl in the QueryCellStyle as shown in the below code snippet. 

gridGroupingControl1.QueryCellStyleInfo += GridGroupingControl1_QueryCellStyleInfo; 
 
private void GridGroupingControl1_QueryCellStyleInfo(object sender, Syncfusion.Windows.Forms.Grid.Grouping.GridTableCellStyleInfoEventArgs e) 
{ 
    if (e.TableCellIdentity.Column != null) 
    { 
        if ((e.TableCellIdentity.Column.MappingName == "GGCIDMulti_2") &&  e.TableCellIdentity.RowIndex > 2) 
        { 
            multiselectionComboBox_2 = new SfComboBox(); 
            multiselectionComboBox_2.DataSource = ds.Tables["DT"].DefaultView; 
            multiselectionComboBox_2.DisplayMember = "Name"; 
            multiselectionComboBox_2.ValueMember = "ID"; 
            multiselectionComboBox_2.DelimiterChar = ","; 
            multiselectionComboBox_2.ComboBoxMode = Syncfusion.WinForms.ListView.Enums.ComboBoxMode.MultiSelection; 
            e.Style.CellType = GridCellTypeName.Control; 
            e.Style.Control = multiselectionComboBox_2; 
        } 
        else if (e.TableCellIdentity.Column.MappingName == "GGCIDMulti_3" && e.TableCellIdentity.RowIndex > 2) 
        { 
            SfComboBox sfComboBox_3 = new SfComboBox(); 
            sfComboBox_3.DataSource = ds.Tables["DT"].DefaultView; 
            sfComboBox_3.DisplayMember = "Name"; 
            sfComboBox_3.ValueMember = "ID"; 
            e.Style.CellType = GridCellTypeName.Control; 
            e.Style.Control = sfComboBox_3; 
 
            //https://help.syncfusion.com/windowsforms/combobox/dropdown 
            // Enable the header in DropDownListView and initialize the custom control. 
            sfComboBox_3.DropDownListView.ShowHeader = true; 
            CustomHeaderUserControl customTextBox_3 = new CustomHeaderUserControl(sfComboBox_3); 
            customTextBox_3.TextBox.Font = sfComboBox_3.DropDownListView.Style.ItemStyle.Font; 
            sfComboBox_3.DropDownListView.HeaderHeight = 23; 
            sfComboBox_3.DropDownListView.HeaderControl = customTextBox_3; 
 
        } 
    } 
}

You have loaded the ComboBox in Expression_GGCIDMulti column and also having different Datasource and the changed value is not in the underlying Datasource, the value will not be changed. Please revert to us with more details if we have misunderstood your requirement.

We could able to understand your requirement. Please provide more details with the video illustration about the requirement. It will be more helpful for us to provide the prompt and timely solution. 

Note : Our SfDataGrid have direct support to add GridComboBoxColumn. Please refer the below given help documentation.

Hi Sampath
Thank you for your answer


1. does not display the content in the gridGroupingControl1.DataSource = GGCds.Tables ["GGCDT"] in SfComboBox

2. does not change the selected items in the SfComboBox in GGCds.Tables ["GGCDT"] this can be seen in test_gridGroupingControl should change after a change in SfComboBox

3. after changing the width of the column gridGroupingControl1 the appearance crashes I send a video and a program

Hi Gregory,  

Sorry for inconvenience 

We have checked the feasibility to achieve your requirement using SfComboBox. We regret that it is not possible to achieve these requirements as it is not possible to add items to the underlying collection of the ComboBox and make it as selected items in the Expression_GGCIDMulti column when editing the value in GGCIDMulti column since it may go infinitely. We regret for the inconvenience caused. Please let know if you need any other assistance from us. 

Regards, 
Sampath Narayanan.S 


GP Gregory Pe February 10, 2022 02:38 PM UTC

we resign from  Expression_GGCIDMulti column

but what about the other columns



SS Sampathnarayanan Sankaralingam Syncfusion Team February 11, 2022 04:18 PM UTC

Hi Gregory,  


We have checked the possibilities to achieve the requirement. You have to set the value manually to the underlying datatable respective to the value of combobox. We have achieved the requirement but still we need to check some use cases. We will check and update you with more details on February 15, 2022. Please find the sample from below link.

Hi Gregory,  


We are deeply regret that we couldn’t able to achieve all cases since there is no direct support of multiselection ComboBox in GridGroupingControl. You have to set the value manually to the underlying datatable respective to the value of combobox. However we have achieved some cases to set the value of comboboxcolumn of gridGroupingControl1 to the respective column of testGridGroupingControl. Please find the sample from the below Link.
