Retrieving values from selected rows

[Matt]

Hi All,

I have a pretty simple task that I am having trouble accomplishing.  I have a GridView that has agent information.  In a hidden column if the GridView I have the AgentId.  I want to allow the user to select a cell (or multiple cells) and click a delete button, which will delete these users from a database. 

I am having trouble retrieving the cell values of the selected cells.  This should something thats easy to do, so I am guessing that I am just missing something here.

As always, thanks in advance for the help!

Hi Matt,

Thank you for writing.

You could get selected cells using the SelectedCells generic collection of a RadGridView. Please review the function provided below as reference:

public string GetSelectedCellsValueByColumn(RadGridView radGridView, string columnName)
{
    if (radGridView.SelectedCells.Count > 0)
    {
        StringBuilder strBuild = new StringBuilder();

        List<GridViewCellInfo> selectedCells = radGridView.SelectedCells;

        for (int i = 0; i < selectedCells.Count; i++)
        {
            GridViewRowInfo row = selectedCells[i].RowInfo;
            strBuild.Append(row.Cells[columnName].Value.ToString());
            strBuild.Append(", ");
        }

        return strBuild.ToString(0, strBuild.Length - 2);
    }
    else
    {
        return null;
    }
}

I hope this was helpful. Do not hesitate to contact me again if you need additional assistance.
