Dynamic adding a row to GridGroupingControl in ASP.Net

[Santosh U]

Hi. I am trying to figure out how to dynamically add a record with 3 columns, one of which is a DropDownList, to a GridGroupingControl in ASP.Net. Does a GridGroupingControl in Web support this feature? First record will be hard-coded and others thereafter will be dynamically added.

Thanks in advance.

Your query belongs to ASP.Net Grid Team and we have forwarded your query to that team. They will update you the details further.

Appreciate your patience.

Hi Santhosh,

Thanks for your interest in Syncfusion products.

Query #1"I am trying to figure out how to dynamically add a record with 3 columns, one of which is a DropDownList"

Your requirement can be achieved by adding the record to grid in button click event using AddNewRecord dynamically. The value for the record is set using SetValue() method.DropDownList can be added as ItemTemplate in QueryCellStyleInfo. Please refer the below code snippet.

[Code behind - C#]

void GridGroupingControl1_QueryCellStyleInfo(object sender, Syncfusion.Web.UI.WebControls.Grid.Grouping.GridTableCellStyleInfoEventArgs e)
{
if (e.TableCellIdentity.TableCellType == GridTableCellType.AlternateRecordFieldCell || e.TableCellIdentity.TableCellType == GridTableCellType.RecordFieldCell)
{
if (e.TableCellIdentity.Column.MappingName == "Category")
{// ItemTemplate Creation.
DropDownList ddl = new DropDownList();
string[] controls = { "Level1", "Level2", "Level3" };
ddl.DataSource = controls;
ddl.DataBind();
ddl.SelectedValue = Convert.ToString(e.Style.CellValue);
TemplateClass temp = new TemplateClass(ddl);
e.TableCellIdentity.Column.ItemTemplate = temp;
}
}
}
//Add button click event for adding record
protected void RecordAdd(object sender, EventArgs e)
{
this.GridGroupingControl1.CurrentTable.AddNewRecord.BeginEdit();
this.GridGroupingControl1.CurrentTable.AddNewRecord.SetValue("ID", 2);
this.GridGroupingControl1.CurrentTable.AddNewRecord.SetValue("Name", "Company2");
this.GridGroupingControl1.CurrentTable.AddNewRecord.SetValue("Category", "Level2");
this.GridGroupingControl1.CurrentTable.AddNewRecord.EndEdit();
}
