Wrong tooltip on RADgrid hyperlink column

[Neo]

Hello All,

We are using RadGrid in one of the project. We have hyperlink column as part of the grid. Now what happens is we have implemented client side biding for the grid. right now when we bind it first time from server it shows currect tooltip for hyperlink column

but as soon as we retrieve data from web service and make client side binding it shows old values on the tooltip for new links.

So if first time data is, John and tool tip is John ,
we do the paging on client side and next data is carl and the tooltip still shows John. 

We have more then 15 hyperlink columns in different radgrid so we are using it widely in the project.
Let me know the quickest way to fix this or remove the tooltip from hyperlink column.

Thanks in advance.

Hi Neo,

When using only client-side databinding the GridHyperLinkColumn does not set a tooltip for the links. Tooltip is set only when using server-side databinding. When you mix the two, the hyperlinks are rendered with a tooltip from the server. Because rebinding the grid on the client does not modify the tooltip, the latter remains the same after binding. This is why you are getting the tooltips rendered from the server on initial load. You can either remove the tooltip or better set the tooltip to the inner text of the hyperlink after binding. You can use RadGrid's client-side OnRowDataBound event for that:

<ClientEvents OnRowDataBound="gridRowDataBound" />

function gridRowDataBound(sender, args)
{
    var gridItem = args.get_item();
    var linkColumnName = "Link";
    var hyperlink = gridItem.get_cell(linkColumnName).getElementsByTagName("a")[0];
    if (hyperlink)
    {
        hyperlink.title = hyperlink.innerHTML;
    }
}

In the above example, "Link" is the UniqueName of my GridHyperLinkColumn.
