How To Get Value of ComboBox?

Hi,

Wondering if you could help. I'm struggling to get a value from a ComboBox. I have the following ComboBox set up:

<sq8:ComboBox runat="server" ID="cboAgree" OnClientSelectedIndexChanged="onSelectedIndexChanged"><Items>

<sq8:ComboBoxItem runat="server" Text="Agree" Value="Agree"></sq8:ComboBoxItem>

<sq8:ComboBoxItem runat="server" Text="Disagree" Value="Disagree"></sq8:ComboBoxItem>

</Items>

</sq8:ComboBox>

<sq:BindableControl runat="server" TargetControlID="cboAgree" DataField="Agreement"></sq:BindableControl>

And the following JavaScript to get the value:

<script type="text/javascript">

Sys.Application.add_load(FormLoad)

function FormLoad()

{

onSelectedIndexChanged(true);

}

function onSelectedIndexChanged(sender, eventArgs)

{

var commentsGrid = document.getElementById("comms");

commentsGrid.style.display = "none";

var item = eventArgs.get_item();

if (item == "Disagree") {

commentsGrid.style.display = "block";

} else {

commentsGrid.style.display = "none";

}

</script>

I get back the following error - "Uncaught TypeError: Cannot read property 'get_item' of undefined"

I have looked at the threads about getting ComboBox values on this forum but just can't seem to get this working.

When the value "Disagree" is selected from the combobox (id of the ComboBox is cboAgree) i want the grid to show. And when Agree is selected, i want the grid to disappear.

Could anyone steer me in the right direction? Thanks!

Error On grid export to excel-ExcelML-URGENT

Hi
I have 2 buttons in .aspx page ,one for pdf export and other for excel export.Pdf works okay.But on excel export, i get error "RegisterRequiresControlState can only be called before and during PreRender. "
I am using dynamically loaded user controls and the grid DataBind() is in the Page_Load of the user control.
The below is the Code in user control. What do I need to do to get rid of this error? I did see the forum answers where it says "Calling Rebind not after PreRender is not supported " .But I am not doing anything on PreRender knowingly.

protected void Page_Load(object sender, EventArgs e)

{

List<ReportDto> reportlt = BuildReport<ReportDto>();

ReportGrid.DataSource = reportlt;

ReportGrid.DataBind();

}

Code in .ascx is

<telerik:RadGrid runat="server" SkinID="main" style="outline: none;" id="ReportGrid">

<ExportSettings>

<Pdf AllowAdd="false" AllowCopy="True" AllowModify="false" AllowPrinting="true" Author="RadTech"

Keywords="None" PageBottomMargin=".1in" PageLeftMargin=".1in" PageRightMargin=".1in"

PageTopMargin="1in" PaperSize="Letter" PageHeight="8.5in" PageWidth="11.69in" Title="Client QA -Case Report" />

<Excel Format="ExcelML" />

</ExportSettings>

<MasterTableView>

<NoRecordsTemplate>

There are no records to display

</NoRecordsTemplate>

<Columns>

....

...

</Columns>

</MasterTableView>

</telerik:RadGrid>

code in aspx.cs page is:

protected void BtnExportToExcel_Click(object sender,EventArgs e)

{

try

{

TrySearch();

} 

        catch

        {

        }

UserControl usr = new UserControl();

usr = ReportHolder.FindControl("CaseReport") as UserControl;

if (usr != null)

{

RadGrid grdExcel = usr.FindControl("ReportGrid") as RadGrid;

grdExcel.ExportSettings.OpenInNewWindow = true;

grdExcel.ExportSettings.ExportOnlyData = true;

grdExcel.ExportSettings.IgnorePaging = true;

grdExcel.MasterTableView.ExportToExcel();

}

Passing multiple values clientside from Radgrid

I have a Radgrid with a RadNumericTextBox in a template column. The OnValueChanged event passes the value to the Javascript function. How do I also pass the value of the Price column of the same row in the same OnValueChanged event?

function Total(sender, eventArgs) {

var total = $find('<%=tbTotal.ClientID %>');

var OldTotal = total.get_value();

var i = eventArgs.get_newValue();

var i2 = eventArgs.get_oldValue();

total.set_value(i + OldTotal - i2);

}

<telerik:RadGrid ID="RadGrid1" runat="server" DataSourceID="SqlDataSource1" >

<MasterTableView datakeynames="Item"

datasourceid="SqlDataSource1" ClientDataKeyNames="Quantity,Price" >

<telerik:GridBoundColumn DataField="Item"

UniqueName="Item">

</telerik:GridBoundColumn>

<telerik:GridTemplateColumn UniqueName="TemplateColumn" >

<telerik:RadNumericTextBox ID="tbQuantity" Runat="server"

RadGrid with template filter does not work correctly.

Hello, I have a database with a numeric field (State) that has the following values: 0, 1, 2, 3 and 4. In the Template Filter I have associated a combobox with the text associated with each value.

I want to see the text both in the field and in the filter, but I do not get it. You can help me see what I have wrong. Thank you

<telerik:GridTemplateColumn DataField="Estado" HeaderText="Estado" UniqueName="Estado" DataType ="System.String" SortExpression="Estado" GroupByExpression="Estado Group by Estado" ReadOnly "true"> 

<ItemTemplate> 

<asp:Label runat="server" 

ID="Estado" Text= '<%# DataBinder.Eval(Container.DataItem, "Estado") %>'> </asp:Label> 

</ItemTemplate> 

<FilterTemplate>

<br>                                        SelectedValue='<%# CType(Container, GridItem).OwnerTableView.GetColumn("Estado").CurrentFilterValue %>'

runat="server" OnClientSelectedIndexChanged="Estado_SelectedIndexChanged"> <Items> 

<telerik:RadComboBoxItem Text="Todo" Value="" Selected="True" /> <telerik:RadComboBoxItem Text="Sin incidencia" Value="0" /> <telerik:RadComboBoxItem Text=

<telerik:RadScriptBlock ID="RadScriptBlock1" runat="server"> 

<script type="text/javascript">

function Estado_SelectedIndexChanged(sender, args) { 

var tableView = $find("<%# TryCast(Container, GridItem).OwnerTableView.ClientID %>");

tableView.filter("Estado", args.get_item().get_value(), "EqualTo");  </script>

Setting mouse pointer style on legend

I'm sure the answer is something simple. I am trying to set my chart's legend cursor (mouse pointer) to "default" after the chart has already been created. I can't seem to figure out the correct syntax. Your help will be greatly appreciated.Thanks in advance.

var radHtmlChartObject = $find("<%=RadHtmlChart1.ClientID %>"); //the standard control object
var kendoChart = radHtmlChartObject.get_kendoWidget(); //the Kendo widget

//Examples that work correctly

kendoChart.options.legend.position = "top";
kendoChart.options.legend.labels.background = "green";

//None of these work for me:
kendoChart.options.legend.item.cursor = "default";
kendoChart.options.legend.item.cursor.style = "default";
kendoChart.options.legend.item[0].cursor = "default";
kendoChart.options.legend.item[0].cursor.style = "default";
kendoChart.options.legend.items.cursor = "default";
kendoChart.options.legend.items.cursor.style = "default";

RadGrid will not show results of RadFilter

I am using RadFilter to filter results in a RadGrid. For whatever reason, it will not filter my results in the rad grid. If I used the asp Grid option though, it does work. Is there a setting I am missing? Pictures attatched show that I should be getting results when I filter for cartoon, using the RadGrid and RadFilter, but nothing comes up.

My code is as follows: (didn't give filter or grid ID names, I am just trying to get it to work at the moment.)

<telerik:RadFilter ID="RadFilter1" runat="server" FilterContainerID="RadGrid1">
</telerik:RadFilter>
 
 

<telerik:RadGrid ID="RadGrid1" runat="server" DataSourceID="ListViewFilter" Height="80px">
<GroupingSettings CollapseAllTooltip="Collapse all groups"></GroupingSettings>
<MasterTableView AutoGenerateColumns="False" DataSourceID="ListViewFilter">

</MasterTableView>
</telerik:RadGrid>
<asp:SqlDataSource ID="ListViewFilter" runat="server" ConnectionString="<%$ ConnectionStrings:Interests.My.MySettings.dbInterests %>" SelectCommand="FilterList" SelectCommandType="StoredProcedure"></asp:SqlDataSource>

Sys.ScriptLoadFailedException

Hello,

on my pages where i use RadAjaxPanel, RadAjaxLoadingPanel, RadGrid, RadPanelBar, RadComboBox, RadMenu and RadScriptManager sometimes i got the following script error:

Sys.ScriptLoadFailedException: The script '/Telerik.Web.UI.WebRessource.axd?_TSM_HiddenField_=ctl00_ScriptManager1_HiddenField&compress=1 .......... could not be loaded.

I'am using ASP .NET 2.0 and RadControls for ASP.NET AJAX 2009.2.701.20. I read about this problem in an other thread but it was for an much older version of the RadControls. So what should i do to solve this problem?
