GridDropDownColumn - How Do I Get the Value During Update?

I have a radgrid that looks like:



<

telerik:RadGrid ID="RadGrid1" runat="server" DataSourceID="MultiEmployeeList" AutoGenerateColumns="False"

CellSpacing="0" GridLines="None" GroupingEnabled="False" AllowMultiRowEdit="false"

AutoGenerateEditColumn="True" HorizontalAlign="Left"Width="800px">

<ClientSettings>

<ClientEvents OnCommand="OnCommand" />

</ClientSettings>

<HeaderContextMenu CssClass="GridContextMenu GridContextMenu_Default">

</HeaderContextMenu>

<MasterTableView DataSourceID="MultiEmployeeList" DataKeyNames="rasID" ClientDataKeyNames="rasID"

EditMode="InPlace">

<RowIndicatorColumn FilterControlAltText="Filter RowIndicator column">

<HeaderStyle Width="20px"></HeaderStyle>

</RowIndicatorColumn>

<ExpandCollapseColumn FilterControlAltText="Filter ExpandColumn column">

<HeaderStyle Width="20px"></HeaderStyle>

</ExpandCollapseColumn>

<Columns>

<telerik:GridBoundColumn DataField="empName" FilterControlAltText="Filter column column"

UniqueName="Name" ReadOnly="true">

</telerik:GridBoundColumn>

<telerik:GridDropDownColumn DataField="rasRoleID" DataSourceID="RoleList" FilterControlAltText="Filter column column"

ListTextField="mrrRoleDesc" ListValueField="mrrID" UniqueName="rasRoleID" EmptyListItemText=" -- Select Role --"

EnableEmptyListItem="True" >

</telerik:GridDropDownColumn>

</Columns>

<EditFormSettings>

<EditColumn FilterControlAltText="Filter EditCommandColumn column">

</EditColumn>

</EditFormSettings>

</MasterTableView>

<FilterMenu EnableImageSprites="False">

</FilterMenu>

</telerik:RadGrid>

I do an AJAX-type webservice post during update, and it all works fine.
My question is, how can I find the value of the combo box the user has selected during update so I can post this back using a web service?
I can get the key value of the row, but finding the new selected value (rasRoleID) is eluding me.

Thanks.

EditMode="PopUp" & InsertItemPageIndexAction

Are there any none issues with EditMode="PopUp" and InsertItemPageIndexAction="ShowItemOnFirstPage"

If I set EditMode="PopUp" the page index does not cahnge to the first page, or any page for that matter and newly inserted records aren't on page one.

This only seems to occur when EditMode="PopUp"

<MasterTableView EditMode="PopUp" Caption="Caption" CommandItemDisplay="Top"

NoMasterRecordsText="No Rows Returned!" DataKeyNames="ID" RetrieveNullAsDBNull="False"

HorizontalAlign="Center" BorderWidth="1" BorderColor="Gray" BorderStyle="Solid"

The 'magic' behind the Recurrence exceptions

I searched the entire forum and I could't find one single explanation on what happens internally to the SQL table that stores the appointments, specifically the field 'RecurranceStorage' when a 'recurring exception' occurs. Please provide me with a link that can help me to understand the magic. I want to know how recurrence series keep track of exceptions like 'moving' one instance of the series to another resource or date/time. Your sample code 'ResouceGrouping' has zero code-behind.Thanks in advance.

On Load Demand ComboBox Error

Hi,

I am trying to implement the automatic onloaddemand mechanism of the RAD combo box. But getting following error when click on dropdown:-

"The result of query can not be enumerated more than once"

Following is the source html for location combo box. Combobox is bind to objectdata source. Highlighted portion is use for onload demand functionality.

<telerik:RadComboBox ID="comboLocation" runat="server" Width="250px" DataTextField="Location_DisplayName"

DataValueField="Location_ID" DataSourceID="LocationDataSource"

AppendDataBoundItems="true" EnableAutomaticLoadOnDemand="true"

onitemsrequested="comboLocation_ItemsRequested" ShowMoreResultsBox="true"
itemsperrequest="5" enablevirtualscrolling="true">

<Items>

<telerik:RadComboBoxItem Text="" />

</Items>
</telerik:RadComboBox>

Not able to find what is happening wrong to cause above error. Have anyone got the same issue while developoing combobox on load demand functionality.

RadGrid deselect not always firing SelectedIndexChanged

Hello, I have the following RadGrid issue:

Multiple row selection is turned on.
Client side selection is turned on.
ASP.NET AJAX RadGrid version 2009.01.0402.35.

All of this is OK:
When I select a row and then postback, SelectedIndexChanged fires correctly.
When I select a 2nd row and then postback, SelectedIndexChanged fires correctly.
When I select a 3rd row and then postback, SelectedIndexChanged fires correctly.
When I deselect a row and then postback, there are two rows selected, and SelectedIndexChanged fires correctly.
When I deselect another row and then postback, there is one row selected, and SelectedIndexChanged fires correctly.

This is the problem: When I deselect the final selected row, so there are now no selected rows, and then post back, SelectedIndexChanged does NOT fire. It happens every time I deselect the final selected row, regardless of how much selecting/deselecting I do.

Here is my ASPX code:

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="AddressTypes.aspx.cs" Inherits="foo.AddressTypes" %>

<%@ Register TagPrefix="telerik" Namespace="Telerik.Web.UI" Assembly="Telerik.Web.UI" %>

<html>

<head runat="server">

<title>Test Page</title>

</head>

<body>

<form runat="server">

<asp:ScriptManager ID="sm" runat="server" />

<asp:ObjectDataSource ID="gridDS" runat="server" TypeName="foo.AddressTypes" SelectMethod="GetRecords" />

<telerik:RadGrid ID="grid" runat="server" DataSourceID="gridDS" OnSelectedIndexChanged="Grid_SelectedIndexChanged"

AllowMultiRowSelection="true">

<ClientSettings>

<Selecting AllowRowSelect="true" />

</ClientSettings>

</telerik:RadGrid>

<asp:Button ID="button" runat="server" Text="Postback" />

</form>

</body>

</html>

Here is my code-behind:

using System;

using System.Collections.Generic;

using System.Web.UI;

namespace foo

{

public partial class AddressTypes : Page

{

protected void Page_Load(object sender, EventArgs e)

{

}

public static Dictionary<string, string> GetRecords()

{

Dictionary<string, string> dict = new Dictionary<string, string>();

dict.Add("Test 1", "Test record number 1");

dict.Add("Test 2", "Test record number 2");

dict.Add("Test 3", "Test record number 3");

dict.Add("Test 4", "Test record number 4");

dict.Add("Test 5", "Test record number 5");

return dict;

}

protected void Grid_SelectedIndexChanged(object sender, EventArgs e)

{

Response.Write("SELECTED INDEXES: " + grid.SelectedIndexes.Count);

}

Everything works fine until that last selected row is deselected. All of the row deselection is done using CTRL-Click, and adding a selection column to the grid is not an option. Can you help me determine why SelectedIndexChanged does not fire when the last selected row is deselected? Thank you.

set the export file name and extension of excel

I have followed a lot of the things online but my export filename seems to work but not the extension of the excel file. It always ends up being aspx and it gives me the trusted file error. I think I am getting this because it does not like the aspx extension.
