How to access GridColumn by UniqueName or through the GridDataItem?

[e-statik]

In ItemDataBound i can access cell using gridDataItem["uniquename"]. But how can i access column associated with this cell ? For instance i need to know what DataType the value in my cell is.

Hello Blokhin

These code-snippets may be helpful:

foreach (GridColumn column in RadGrid1.MasterTableView.RenderColumns)
{
    if (column.UniqueName == "myUniqueColumnName")
    {
        string columnType = column.ColumnType;
        string dataType = column.DataTypeName;
    }
}

protected void RadGrid1_ColumnCreated(object sender, GridColumnCreatedEventArgs e)
{
    if (e.Column.UniqueName == "myUniqueColumnName")
    {
        string columnType = e.Column.ColumnType;
        string dataType = e.Column.DataTypeName;
    }
}

string columnType = RadGrid1.MasterTableView.GetColumnSafe("myUniqueColumnName").ColumnType;
string dataType = RadGrid1.MasterTableView.GetColumnSafe("myUniqueColumnName").DataTypeName;

Is it possible to format the data in the column cells?

Hello John,

Indeed, it is possible thanks to the DataFormatString property.

<telerik:GridBoundColumn DataField="Value" HeaderText="Value" UniqueName="Value"
  SortExpression="Value" DataType="System.Double" DataFormatString="{0:G17}">
</telerik:GridBoundColumn>
