Adding Validator to EditMode InPlace RadGrid

[J]

I have successfully added a RequiredFieldValidator on my grid, whose EditMode="InPlace":

if ((e.Item is GridDataInsertItem) && e.Item.IsInEditMode)
{
    //  Insert is clicked
    GridEditableItem editedItem = e.Item as GridEditableItem;

    GridDataItem dataItem = (GridDataItem)e.Item;

    GridEditManager editMan = editedItem.EditManager;

    GridDropDownListColumnEditor editor = editMan.GetColumnEditor("Id") as GridDropDownListColumnEditor;

    RadComboBox dropDownList1 = editedItem["Id"].Controls[0] as RadComboBox;

    TableCell cell = (TableCell)editor.ContainerControl;
    //Declare the validator
    RequiredFieldValidator rfv = new RequiredFieldValidator();

    rfv.ControlToValidate = dropDownList1.ID;
    rfv.ID = "valId";
    rfv.ErrorMessage = @"<img src='Images/cautionIcon.png' class='Validation' />";

    //Add the validator to the cell
    cell.Controls.Add(rfv);

    editor.ComboBoxControl.Skin = "MySkin";
    editor.ComboBoxControl.EnableEmbeddedSkins = false;
    editor.ComboBoxControl.DropDownWidth = Unit.Pixel(500);
    editor.ComboBoxControl.Width = Unit.Pixel(380);

    var erds = (from result in _s
             where !_Ds.Any(dto =>
                 dto.Id == result.SystemID)
             select result).ToList<DTO>();

    editor.DataSource = s;

    editor.DataBind();
}
else if ((e.Item is GridEditableItem) && e.Item.IsInEditMode)
{
    //  Edit is clicked
    GridEditableItem editedItem = e.Item as GridEditableItem;

    GridDataItem dataItem = (GridDataItem)e.Item;

    DTO affected = (DTO)e.Item.DataItem;

    GridEditManager editMan = editedItem.EditManager;

    GridDropDownListColumnEditor editor = editMan.GetColumnEditor("Id") as GridDropDownListColumnEditor;

    RadComboBox dropDownList1 = editedItem["Id"].Controls[0] as RadComboBox;

    TableCell cell = (TableCell)editor.ContainerControl;
    //Declare the validator
    RequiredFieldValidator rfv = new RequiredFieldValidator();

    rfv.ControlToValidate = dropDownList1.ID;
    rfv.ID = "Id";
    rfv.ErrorMessage = @"<img src='Images/cautionIcon.png' class='Validation' />";

    editor.ComboBoxControl.Skin = "EPSS";
    editor.ComboBoxControl.EnableEmbeddedSkins = false;
    editor.ComboBoxControl.DropDownWidth = Unit.Pixel(500);
    editor.ComboBoxControl.Width = Unit.Pixel(380);

    var erds = (from result in _s
                where !_as.Any(dto =>
                    dto.Id == result.SystemID && dto.Id != affected.Id)
                select result).ToList<DTOSystem>();

    editor.DataSource = s;

    editor.DataBind();

    editor.SelectedValue = affected.Id.ToString();

}

I know my code is convaluted, but basically its correctly adding a RequiredFieldValidator when you click insert.  But not sure why, its now not putting an identical RequiredfieldValidator when I click 'Edit'?  I would think it would roughly be the same code.

Hello J,

For an edit operation, with Inplace editing, the item will be of type GridDataItem. Hence, you need to check

if ((e.Item is GridDataItem) && e.Item.IsInEditMode)

I hope this gets you started properly.

I'm trying to add Required and Range validators to a single inplace edit column with code below.  The first works, the second doesn't.  Any help is appreciated.

 

 

if (e.Item is GridEditableItem && e.Item.IsInEditMode)

 

{

 

 

GridEditableItem editItem = (GridEditableItem)e.Item;

 

 

 

GridTextBoxColumnEditor editor = (GridTextBoxColumnEditor)editItem.EditManager.GetColumnEditor("WaterCapacity");

 

 

 

TableCell cell = (TableCell)editor.TextBoxControl.Parent;

 

 

 

RequiredFieldValidator valReq = new RequiredFieldValidator();

 

editor.TextBoxControl.ID =

 

"ControlId";

 

valReq.ControlToValidate = editor.TextBoxControl.ID;

valReq.ErrorMessage =

 

"Enter capacity 3,000 - 16,000";

 

valReq.ForeColor = System.Drawing.

 

Color.Red;

 

cell.Controls.Add(valReq);

 

 

RequiredFieldValidator valRange = new RequiredFieldValidator();

 

valRange.ControlToValidate = editor.TextBoxControl.ID;

valRange.ErrorMessage =

 

"Enter capacity 3,000 - 16,000";

 

valRange.ForeColor = System.Drawing.

 

Color.Red;

 

cell.Controls.Add(valRange);

}

Hallo,

when trying to add validatiogroups as explained in http://www.telerik.com/community/forums/aspnet-ajax/grid/radgrid-perform-validation-only-in-edit-or-insert-mode-and-not-both.aspx im experiencing the issue that in InPlace-Mode you cannot distinguish between an insert and edit Item by asking :

if (e.Item is GridEditFormInsertItem)

as it never is!
Is ther an alternative Approach for InPlace- editing?

Regards Michael

Hello Michael,

In this case the item is of type GridDataInsertItem. You can use the approach demonstrated in the following article to achieve the requested functionality:

Hope this helps.
