Object reference not set to an instance of an object

I have nested grids. in child table I have this:

<telerik:GridDropDownColumn AllowFiltering="true" DataField="Customer_Id"

DataSourceID="entityDataSource1" DropDownControlType="RadComboBox"

HeaderText="Customer Name" ListTextField="Name" ListValueField="Customer_Id"

UniqueName="CustomerNameDropDown" AllowAutomaticLoadOnDemand="true"> </telerik:GridDropDownColumn>

when I try to select it says: Object reference not set to an instance of an object
So, automatic load on demand does not work with nested grids? Or I have to use edit template?

ComboBox

Telerik radgrid edit form z-index in IE 10

Version : I am using the latest Telerik ASP.Net suite - Q3 2013.
Control : Telerik RadGrid
Environment: SharePoint 2013, using Telerik Radgrid for custom development.
Issue:
I have 2 rad grids on the page. I am using Popup Edit Form with custom template. The grid has 20 columns, hence the edit form has got lot of input fields. The problem I have is, in IE 10, the pop up is showing only half of the screen until the grid boundaries, the rest are all hidden. I am attaching the bad screenshot from IE. It is rendering fine in FF, you will see that in the attachment. I did set popup z-index to very high number "100001", but it did not fix the issue. Any direction is helpful as I have very tight deadline.

Thanks
Ramya

Transposing Rows->Grids and vice versa

Just checking if this would be doable:

We have a need to transpose the content of the RadGrid, i.e. make columns in the source data become rows in the RadGrid, and vice-versa.
I know I could do this "manually" be transposing the source datatable, but I wonder if there's any support for this built-in.

Thanks!
/Fredrik

Passing data to context in RadAutoCompleteBox throws an error


How to pass additional data to context from RadAutoCompleteBox
This is on my markup, the retrieval of data is working but passing the data to context from the RadAutoCompleteBox has a problem.
<

telerik:RadAutoCompleteBox

ID="racbTest"

runat="server"

DataTextField="Text"

AutoPostBack="False"

TextSettings-SelectionMode="Single"

OnClientItemsRequesting="TestRequesting"

InputType="Text"

AllowCustomEntry="True">

<WebServiceSettings

Path="../DataSources/DataLoader.asmx"

Method="SearchTest">

</WebServiceSettings>

</telerik:RadAutoCompleteBox>

<telerik:RadCodeBlock runat="server">

<script>

function TestRequesting(sender, args) {

args.get_context()["Foo"] = "Bar";

}

</script>

</telerik:RadCodeBlock

>





and this is the code in the web service




[WebMethod]
public AutoCompleteBoxData SearchTest(RadAutoCompleteContext context)
{
   string searchString = context.Text;
   string foo = context["Foo"].ToString();
}



the problem is in the WebMethod, the context["Foo"] throws an error that

The given key was not present in the dictionary.

Any help would be appreciated.. Thanks in advance.

Keep Grid row "selected" after postback

Hello all,

I have been looking for a while now, and have not been able to find a solution for my problem, which could possible be very easy to fix.

I have a grid in which when the user selects a row I want it to stay highlighted. Simple enough, I can make it work, as long as there is no postback.

I have looked at numerous posts, including Telerik's demos (http://demos.telerik.com/aspnet-ajax/grid/examples/functionality/selecting/row-selection/defaultvb.aspx?#qsf-demo-source, http://www.telerik.com/help/aspnet-ajax/grid-selecting-row-with-click-client-side.html) and yet, I cannot find a solution.

This is the style on my page:

<style type="text/css">

.rgSelectedRow, .rgSelectedRow > td

{

padding:4px;

border-right: solid 1px #CBD2DA;

background:gray !important;

}

</style>

This is the Grid's client settings:

<ClientSettings>

<Selecting AllowRowSelect="True"></Selecting>

<ClientEvents OnRowClick="namespace.rowClick" />

</ClientSettings>

Now, the rowClick JS:

rowClick: function (sender, eventArgs) {

var masterTable = $find('<%=grdSpam.RadGrid.ClientID%>').get_masterTableView();

var rowindex = eventArgs.get_itemIndexHierarchical();

var dataItem = masterTable.get_dataItems()[rowindex].get_element();

var spamFilterID = dataItem.attributes["SpamFilterID"].value;

$find('<%=pnlSpamQuarantine.ClientID%>').ajaxRequest('ViewFile' + '|' + spamFilterID + '|' + rowindex);

}

Now, when the user clicks on a row, it stays highlighted as long as I remove the ajaxRequest.
I have also tried to set the EnablePostBackOnRowClick and using it instead of the Javascript, but the problem remains.

In an effort to force the row to be selected coming back, I have also added code to the AjaxRequest that sets the row.Selected = True. And I verified that it is still True during the Grid PreRender event.

BTW, I am not using the GridClientSelectColumn.

Can anyone shed a light as to what I am missing here?

Thanks,
Alex

Clickable Data Point Implementation

I am looking at RadHtmlChart. At the moment, I don’t know how to make the data points clickable easily.

In our scenario, the URL values for each data point will be constructed during the process of binding the data to the chart on the server side.

Can anybody advise?

Thanks!

[Solved] IE7 vs IE8 anomaly

Is there anything in the RadGrid that would cause the GroupBy rendering to behave differently on IE7 vs IE8?

I have this grid defined:

<telerik:RadGrid ID="grdWorkflow" Skin="Outlook" AutoGenerateColumns="False" GridLines="None"

Width="900px" OnNeedDataSource="grdWorkflow_NeedDataSource" OnItemDataBound="grdWorkflow_ItemDataBound"

OnItemCreated="grdWorkflow_ItemCreated" OnColumnCreated="grdWorkflow_ColumnCreated"

runat="server">

<ClientSettings AllowColumnsReorder="false">

<Resizing AllowColumnResize="true" />

</ClientSettings>

<MasterTableView Caption="List of workflows" DataKeyNames="GroupID" ClientDataKeyNames="GroupID,StepID"

GroupsDefaultExpanded="true" TableLayout="Fixed" Style="float: left;" Summary="View Workflow">

<NoRecordsTemplate>

<div class="bold">

There are no approvers set up to approve this ITPR. You must either select a manager

to approve or contact your Customer Service Representative (CSR) for further assistance.

</div>

</NoRecordsTemplate>

<GroupByExpressions>

<telerik:GridGroupByExpression>

<SelectFields>

<telerik:GridGroupByField HeaderValueSeparator=" " FieldName="StepName" />

</SelectFields>

<GroupByFields>

<telerik:GridGroupByField FieldName="ArtificialSortingField" />

</GroupByFields>

</telerik:GridGroupByExpression>

</GroupByExpressions>

<Columns>

<telerik:GridBoundColumn UniqueName="StepID" DataField="StepID" Display="false">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn UniqueName="StepName" HeaderText="Step Name" DataField="StepName"

Display="false">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn UniqueName="GroupID" HeaderText="GroupID" DataField="GroupID"

Display="false">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn UniqueName="GroupName" HeaderText="Approval Group Name"

DataField="GroupName">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn UniqueName="RoleID" HeaderText="Role ID" DataField="RoleID"

Display="false">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn UniqueName="RoleName" HeaderText="Role" DataField="RoleName">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn UniqueName="SectionName" HeaderText="Section" DataField="SectionName">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn UniqueName="Approvers" HeaderText="Potential Approvers"

DataField="Approvers">

</telerik:GridBoundColumn>

</Columns>

</MasterTableView>

</telerik:RadGrid>

The output rendering on IE7 looks like:

<tr class="rgGroupHeader">
    <td class="rgGroupCol">
        <td colSpan="1">
            <p>
                ...

On IE8 & IE9 it renders to:

<tr class="rgGroupHeader">
     <td class="rgGroupCol">
         <td colSpan="4">
             <p>
                 ...

I could understand if different versions of IE do things differently, or if we had some rogue CSS changing things, but why is the RadGrid rendering differently by browser? This causes the grouping to look not look correct on the IE7.
