Mixed readonly and read-write rows?

[Jeff]

I am populating a RadGrid from a DataTable. Each of the DataRows in the DataTable has a "readonly" column with a value of true or false.

The grid currently has a GridEditCommand column, and a GridButtonColumn that triggers the "Delete" command.

What I need is for rows that display records for which "readonly" is true to be read-only.  I need the icon in the GridEditCommand column to be different, and for clicking it to bring up a view-details form, instead of an edit form.  And I need the link in the "Delete" GridButtonColumn to be absent.

It looks like it'd be pretty straightforward to create a table that doesn't allow the user to edit or to delete records, but I need to be able to have some rows editable and some not.

Where should I start?

Hello Jeff,

In order to achieve this, check the value of "readonly" column in ItemDataBound event and make the Delete button visible/invisible based on that value. Similarly based on that value you can change the icon for edit button. And if you want separate form for edit and view details, you can try the following approach. Use FormTemplate for edit and add two Ajax panel (one for edit form and other for viewing details). Initially make the visibility of second panel(for viewing details) as false. And in ItemCommand event check for the Command Name and if it is Edit Command with 'readonly' value as 'true' hide the first panel and show the second one.

ASPX:

<telerik:GridEditCommandColumn ButtonType="ImageButton" UniqueName="EditCommandColumn">
</telerik:GridEditCommandColumn>
<telerik:GridButtonColumn CommandName="Delete" Text="Delete" UniqueName="DeleteButton">
</telerik:GridButtonColumn>

C#:

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)

    {

        if (e.Item is GridDataItem)

        {

            GridDataItem item = (GridDataItem)e.Item;

            DataRowView rowview=(DataRowView)item.DataItem;

            string value=rowview["readonly"].ToString();

            if (value=="True")

            {

                LinkButton deletebtn = (LinkButton)item["DeleteButton"].Controls[0];

                deletebtn.Visible = false;

                ImageButton editButton = (ImageButton)item["EditCommandColumn"].Controls[0];

                editButton.ImageUrl = "~/Images/Bitmap1.gif";

               


            }

        }

    }

Thanks,
Princy.

That's mostly working, except that I can't get the "Edit" tool-tip to change, on a row-by-row basis.

If I set "EditText=" in the markup for the GridEditCommandColumn, that works, but it changes the tool-tip for the icon on every row.

So I'm trying to set the tool-tip in RadGrid_ItemDataBound:

if (e.Item is GridDataItem)
{
    GridDataItem dataItem = e.Item as GridDataItem;
    TableCell editCell = dataItem["EditCommandColumn"];
    editCell.ToolTip = "XXX";
}

The tool-tip on the icon stays "Edit".

A clarification on the above.

Setting tooltip, on the cell, was actually changing the tooltip on the cell, but it wasn't changing the tooltip on the image.  The blank area around the image had the tooltip I had wanted.

if (e.Item is GridDataItem)
{
    GridDataItem dataItem = e.Item as GridDataItem;
    TableCell editCell = dataItem["EditCommandColumn"];
    ImageButton editButton = editCell.Controls[0] as ImageButton;
    editButton.ImageUrl = "../img/view.gif";
    editButton.ToolTip = "View";
}

Hi Jeff,

More information about how to localize the Edit/Update/Cancel buttons text is available here:
Localizing edit command column

Give it a try and let me know if it works as expected.
