<AjaxSettings>

<telerik:AjaxSetting AjaxControlID="RadGrid1">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="RadGrid1"></telerik:AjaxUpdatedControl>

</UpdatedControls>

</telerik:AjaxSetting>

</AjaxSettings>

</telerik:RadAjaxManager>

<telerik:RadAjaxLoadingPanel ID="RadAjaxLoadingPanel1" runat="server">

</telerik:RadAjaxLoadingPanel>

<telerik:RadGrid ID="RadGrid1" runat="server" EnableViewState="true" ShowStatusBar="true"

ShowFooter="True" onitemcommand="RadGrid1_ItemCommand"

ondeletecommand="RadGrid1_DeleteCommand"

oninsertcommand="RadGrid1_InsertCommand"

onupdatecommand="RadGrid1_UpdateCommand"

onneeddatasource="RadGrid1_NeedDataSource" >

<MasterTableView DataKeyNames="Title" AutoGenerateColumns="false" EditMode="InPlace" CommandItemDisplay="TopAndBottom" CommandItemSettings-AddNewRecordText="Add New Item" >

<Columns>

<telerik:GridEditCommandColumn ButtonType="ImageButton">

</telerik:GridEditCommandColumn>

<telerik:GridButtonColumn ConfirmText="Delete this product?" ConfirmDialogType="RadWindow"

ConfirmTitle="Delete" ButtonType="ImageButton" CommandName="Delete" ConfirmDialogHeight="100px"

ConfirmDialogWidth="220px">

</telerik:GridButtonColumn>

<telerik:GridTemplateColumn DataField="Title" HeaderText="Product Number" UniqueName="ProductNumber"

Visible="true">

<InsertItemTemplate>

<telerik:RadTextBox ID="RadtxtPrdNumber" runat="server" Text='<%# Bind("Title") %>' >

</telerik:RadTextBox>

</InsertItemTemplate>

<EditItemTemplate>

<telerik:RadTextBox ID="RadtxtPrdNumber" runat="server" Text='<%# Eval("Title") %>' >

</telerik:RadTextBox>

</EditItemTemplate>

<ItemTemplate>

<telerik:RadTextBox ID="RadtxtPrdNumber" ReadOnly="true" runat="server" Text='<%# Eval("Title") %>' />

</ItemTemplate>

</telerik:GridTemplateColumn>

</Columns>

</MasterTableView>

<ClientSettings EnableRowHoverStyle="true">

</ClientSettings>

</telerik:RadGrid>

<asp:Button ID="btnSubmit" runat="server" Text="Submit"

onclick="btnSubmit_Click" />

</div>

protected void RadGrid1_InsertCommand(object sender, GridCommandEventArgs e)

{

GridEditableItem item = e.Item as GridEditableItem;

Hashtable values = new Hashtable();

item.ExtractValues(values);

string ti = values["Title"].ToString();

}

In the Insercommand code, values is coming as null.
How to fix this?
Thanks

CommandItemTemplate and mixed mode

Hi,

in my application, I made a custom Grid control who inherit from RadGrid.

I want every grid to have the ExportToExcel command. But I also want, in some grid, add another "custom" command.

So I create a class who implement the ITemplate interface in my custom grid control, I use this template. It works good.

But now, in some grid, I want to add a custom DropDoxnList in the Grid Command Item Display area. So I add a <CommandItemTemplate> tag in my aspx. But as I can see, this tag is override by my template.

Is it possible to mix programatic and declarative mode ?

Thanks !

Problems Obtaining Date from Java

Hello,

I am simply trying to obtain the date selected from the RadDatePicker control through javascript as I am trying to pass the value to another page as a parameter for an SQL query the page performs when loading. However, I am having a problem with the format the date is returing. I have tried both get_selectedDates and get_textBox with no luck in returning a date that is in a datetime format for the parameter. With get_seletedDates I am getting a long formatted style not in the correct format while get_textBox doesn't return a date value, only that it is an HTMLelement or something along that lines.

Is there a way to get the date that is in the text box portion of the datepicker to return how it actually shows in the date picket, for instance 12/10/2012?

Thanks,
Ron

DataRow[] changedRows = ordersTable.Select("Title = " + Convert.ToString(editedItem.OwnerTableView.DataKeyValues[e.Item.ItemIndex]["Title"]));

In the changedRows line, i am getting error as: Cannot perform '=' operation on System.String and System.Int32.

[Solved] RadGrid Export to Excel in IE9

I have a rad grid that is AJAXified through a RadAjaxManager and I use a javascript function to stop the async request so I can export. This works perfectly in Chrome and Firefox. But does not seem to work in internet explorer. The page just refreshes. Any workarounds to this?

<telerik:RadScriptManager ID="RadScriptManager1" runat="server">

</telerik:RadScriptManager>

<script type="text/javascript">

Sys.WebForms.PageRequestManager.getInstance().add_initializeRequest(initRequest);

function initRequest(sender, args) {

if (args.get_postBackElement().id.indexOf("btn_ExcelExport") != -1) {

args.set_cancel(true); //stop async request

sender._form["__EVENTTARGET"].value = args.get_postBackElement().id.replace(/\_/g, "$");

sender._form["__EVENTARGUMENT"].value = "";

sender._form.submit();

return;

}

</script>

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">

<AjaxSettings>

<telerik:AjaxSetting AjaxControlID="rg_Clients">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="rg_Clients" />

//Dont need to see the filter boxes in the excel sheet

foreach (GridFilteringItem Filter in rg_Clients.MasterTableView.GetItems(GridItemType.FilteringItem))

Filter.Visible = false;

//Data Admin and Site Admin can export all Clients, Sales Admin can export their own and who they are supervising,

// and Sales Person can only export their own

if (UserRoles.Contains("Sales Admin"))

{

string Source = PageController.GetUserFullName((Guid)Membership.GetUser().ProviderUserKey);

List<string> Sources = ClientController.GetSupervisorSources((Guid)Membership.GetUser().ProviderUserKey);

if (rg_Clients.MasterTableView.FilterExpression != String.Empty)

rg_Clients.MasterTableView.FilterExpression += "AND ";

string QueryFilter = "([Sources] LIKE \'%" + Source + "%\') ";

foreach (string S in Sources)

QueryFilter += "OR ([Sources] LIKE \'%" + S + "%\') ";

rg_Clients.MasterTableView.FilterExpression += QueryFilter;

}

else if (UserRoles.Contains("Sales Person"))

{

string Source = PageController.GetUserFullName((Guid)Membership.GetUser().ProviderUserKey);

if (rg_Clients.MasterTableView.FilterExpression != String.Empty)

rg_Clients.MasterTableView.FilterExpression += "AND ";

rg_Clients.MasterTableView.FilterExpression += "([Sources] LIKE \'%" + Source + "%\') ";

}

rg_Clients.MasterTableView.ExportToExcel();

The rest of the columns are created programmatically on the first page load as some of the grid bound columns implement custom filters for google-like filtering and some are dropdownlists etc.
