Change row selection style dynamically
posted

Hello,

I am trying to replicate a "Copy selected row" on a webdatagrid.

I have a WebDataGrid with Selection behavior enabled and RowSelectType set to "Single". When the user selects any of the rows, I want to offer the possibilty of duplicating the contents of the selected row by "copy-paste" like functionality (i.e. "Ctrl C" to copy contents and then "Ctrl + V" to paste the contents elsewhere).

I want to highlight the selected row in some different way than a normal row selection, so the user is aware that the contents of that row are the ones being copied, and that it is not a normal selection of a row.

I need to do this from client side.

Googling around, I've reached the conlusion that I have to change the SelectedRowSelectorCssClass of the Selection behavior dynamically through Javascript, and I got to the point below, but it does not work.

Do you know how can I change the SelectedRowSelectorCssClass dynamically from client/Javascript?

    <style type="text/css">
    .CopyHighlightCSSClass
    {
        background-color: Red;
        background-image:none;
        color:Lime;
    }

    .DefaultSelectCSSClass
    {
        background-color: Blue;
        background-image:none;
        color:Black;
    }
    </style>

function CopyWebImageButton_Click(oButton, oEvent) {

    var webGrid = $find("MyWebDataGrid");

    webGrid.get_behaviors().get_selection()._selectedRowSelectorCss = "CopyHighlightCSSClass";

    // Rest of copy logic

   ...

}

function PasteWebImageButton_Click(oButton, oEvent) {

    var webGrid = $find("MyWebDataGrid");

    webGrid.get_behaviors().get_selection()._selectedRowSelectorCss = "DefaultSelectCSSClass";

    // Rest of copy logic

}
