    <p>I have a RadGrid that has a column, <em>Loss Amount</em>, which I would like to be able to sort. Currently it does sort, but only by string value. I have the column type as GridNumericColumn. How can I do it?</p> <p>My code is listed below. I am also formatting the column text to show the currency. One thing I did notice is that I am returning a string value from the Format method. Could this be the reason?</p> <h2>Column:</h2> <pre><code>&lt;rad:GridNumericColumn DataField="Loss Amount" UniqueName="Loss Amount" HeaderText="Loss Amount" SortExpression="Loss Amount" \&gt; &lt;HeaderStyle Width="140"&gt; &lt;ItemStyle Width="140" HorizontalAlign="Right"ForeColor="Maroon" /&gt; &lt;/rad:GridNumericColumn&gt;` </code></pre> <h2>NeedDataSource Event:</h2> <pre><code>protected void grdCustomerAssignments_NeedDataSource(object source, Telerik.Web.UI.GridNeedDataSourceEventArgs e) { GetAssignments(); grdCustomerAssignments.DataSource = Assignments; } private void GetAssignments() { if (Assignments == null) Assignments = new DataTable(); SPList list = SPContext.Current.Web.Lists["Listings"]; SPView view = GetCustomerView(); SPListItemCollection items = list.GetItems(view); Assignments = items.GetDataTable(); foreach (DataColumn column in Assignments.Columns) { column.ColumnName = XmlConvert.DecodeName(column.ColumnName); } Assignments.AcceptChanges(); } </code></pre> <h2>ItemDataBound Event:</h2> <pre><code>protected void grdCustomerAssignments_ItemDataBound(object sender, GridItemEventArgs e) { FormatCurrency(item["Loss Amount"].Text); } protected string FormatCurrency(string text) { if (text.Length &gt; 3) { string result = String.Empty; char[] tmpArray = text.ToCharArray(); Array.Reverse(tmpArray); string tmpString = new String(tmpArray); while (tmpString.Length &gt; 3) { string threeChars = tmpString.Substring(0, 3); result = String.Concat(result, threeChars, ","); tmpString = tmpString.Remove(0, 3); } result = String.Concat(result, tmpString); tmpArray = result.ToCharArray(); Array.Reverse(tmpArray); text = new String(tmpArray); } return String.Concat("$ ", text); } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
