Accessing control in current row

[Administrator]

Lets say a user selected a row and entered edit mode.
A dropdown was loaded with certain values and a certain value was selected, now i would like to get to another dropdown in the same row and fill it with data.
In asp.net GridView it was something like this:

this.GridView1.Rows[this.GridView1.EditIndex].FindControl("someContorlId") as DropDownList

Hi Eran,

Thank you for your interest in Syncfusion Products.

The embedded controls (EditItemTemplate) in a Grid row can be accessed by iterating through Grid top level row. Please refer a code snippet below to achieve this using DataSourceControlRowUpdating event.

    void GridGroupingControl1_DataSourceControlRowUpdating(object sender, GridDataSourceControlRowUpdateEventArgs e)
    {
        Label1.Text = "";

        DropDownList dropdown = null;
        foreach (TableRow row in this.GridGroupingControl1.TopLevelTable.Rows)
        {
            if (row is GridRow)
            {
                GridRow gridRow = row as GridRow;

                if (gridRow.Record != null)
                {
                    foreach (GridCell gridCell in gridRow.Cells)
                    {
                        if (gridCell.ColumnDescriptor.Name == "Country")
                        {
                            foreach (Control cntl in gridCell.Controls[0].Controls)
                            {
                                if (cntl is DropDownList)
                                {
                                    dropdown = cntl as DropDownList;
                                    GridCellTemplated grid = (GridCellTemplated)dropdown.Parent.Parent;
                                    GridRow gridrow1 = grid.Row;

                                    Label1.Text += gridrow1.Record.GetValue("EmployeeID") + "--" + gridrow1.Record.GetValue("FirstName") + "--" + dropdown.SelectedItem.Text + "
";
                                    gridRow.Record.SetValue("Country", dropdown.SelectedItem.Text);
                                }
                            }
                        }
                    }
                }
            }
        }
    }

The steps followed here are,
- Get the TableRow in the TopLevelTable
- Check if that Row is GridRow if so Iterate the Gridcells
- Find the TemplatedControl and the value.

Refer a sample illustrating the above.
