Q1 2012 (Version 2012.1.215)

Breaking change: Since the Beta release of Q1 2012 the nodes of the treeview have their text html encoded.

Reason: There were problems when using LoadOnDemand through WebService and ServerSideCallBack. When a node with html in the text was added a server error occurred upon postback.

Solution: From the upcoming Latest internal build the encoding will be optional through the property EnableNodeTextHtmlEncoding and it will be disabled by default.

RadGrid does not populate

Hi,
I am using 2 Stored Procedures to populate 2 different RadGrids. For RadGrid1, OnNeedDataSource event calls a handler function inside which a SP is executed and the data table is equated to RadGrid1.DataSource. Now, I want to populate RadGrid2 when a row is selected in RadGrid1. For this, OnRowSelected event of RadGrid1 is handled by a Javascript function that is extracting some specific cell values of the selected row and initiates an ajaxRequest() with argument string passed. I am using a RadAjaxManager which looks like :

<

telerik:RadAjaxManager ID="RadAjaxManager1" runat="server" OnAjaxRequest="RadAjaxManager1_OnAjaxRequest">

<telerik:AjaxSetting AjaxControlID="RadGrid1">

<telerik:AjaxUpdatedControl ControlID="RadGrid1" LoadingPanelID="RadAjaxLoadingPanel1" />

<telerik:AjaxUpdatedControl ControlID="RadGrid2" LoadingPanelID="RadAjaxLoadingPanel1" />

</UpdatedControls>

</telerik:AjaxSetting>

</AjaxSettings>

</telerik:RadAjaxManager>

In Code-Behind, I have a handler function RadAjaxManager1_OnAjaxRequest() for handling the ajax request. Inside RadAjaxManager1_OnAjaxRequest, I am passing on the arguments to execute an SP and equating the data table returned to RadGrid2.DataSource, as below :

protected

void RadAjaxManager1_OnAjaxRequest(object sender, AjaxRequestEventArgs e)

{

String argument = e.Argument;

String[] args = argument.Split("^".ToCharArray());

NameValueCollection parameters = new NameValueCollection();

parameters.Add("@par1", args[0]);

parameters.Add("@par2", args[1]);

parameters.Add("@par3", args[2]);

RadGrid2.DataSource = obj.ExecuteSP("MySP", parameters);

RadGrid2.Rebind();
}

The problem arises now, when I select a row in RadGrid1, I do not see any RadAjaxLoadingPanel being loaded. Moreover, the RadGrid2 does not populate. However, While debugging I am able to see that the rows are being returned(RadGrid2.DataSource.Rows.Count is greater than 0).

Thanks,
Anup

Filter Options Displayed above Grid when Filter Button Clicked

I've inherited a project that is using RadGrid for data display that uses Filtering. If I click the Filter Icon to select an option from the list, prior to entering any filter criteria, all filter options are displayed at the very top of the page in very cheesy, style-less text. Once I add a criteria into the filter box and click the icon, the filter options display inline as desired.

The requirement is for the user to be able to change the default Filter Menu prior to entering criteria.

Anyone have an idea why that happens?

RadGrid cell text reset on row selection.

I have a radgrid and one of the columns is a GridButtonColumn with a ButtonType="PushButton" with the default text set to "Add". On the ItemDataBound routine I update the text value with the number of items that were added. So when the grid rebinds it now displays the number of added items. Works fine up to now.

Here is where it gets messed up. If I select a row in the grid, all the values in the column reset back to "Add". It seems that the re-rendering of the grid resets all the column values back to the defaults. If the grid is re-bound the values are back again. So it's not a data issue, it's a rendering issue on row selection.

I completely removed any code in the OnSelectedIndexChanged event, so it's nothing to do with any code in that event. It has something to do with the AllowRowSelect directive with EnablePostBackOnRowClick="true". The ItemDataBound routine is not called on row selection, is there another event I can re-set my values to? Would I have to write a routine that loops through each row and sets the proper values after the selection has been made?

I would think the the databindings should persist after a row selection.

<telerik:RadGrid ID="rg_ExportDetail" runat="server" ShowStatusBar="true" OnItemDataBound="rg_ExportDetail_ItemDataBound" OnSelectedIndexChanged="rg_ExportDetail_SelectedIndexChanged"

OnNeedDataSource="rg_ExportDetail_NeedDataSource" OnItemCommand="rg_ExportDetail_ItemCommand" Skin="Vista"

<div>There are no records to display</div>

</NoRecordsTemplate>

<telerik:GridBoundColumn DataField="ExportItemID" UniqueName="ExportItemID" Visible="false" />

<telerik:GridBoundColumn DataField="ExportDate" UniqueName="ExportDate" Visible="true" HeaderText="ExportDate" />

<telerik:GridBoundColumn DataField="Description" UniqueName="Description" Visible="true" HeaderText="Description" HeaderStyle-Width="300px" />

<telerik:GridBoundColumn DataField="ECL" UniqueName="ECL" Visible="false" HeaderText="ECL#" />

<telerik:GridBoundColumn DataField="Quantity" UniqueName="Quantity" Visible="false" HeaderText="Quantity" />

<telerik:GridBoundColumn DataField="UnitValue" UniqueName="UnitValue" Visible="false" HeaderText="Unit Value" DataType="System.Double" DataFormatString="{0:C}"/>

<telerik:GridBoundColumn DataField="TotalValue" UniqueName="TotalValue" Visible="true" HeaderText="Total Value" />

<telerik:GridButtonColumn ButtonType="PushButton" UniqueName="Consignees" text="Add" HeaderText="Consignee(s)" CommandName="AddConsignees" ItemStyle-HorizontalAlign="Center" HeaderStyle-Width="120px" />

<telerik:GridButtonColumn ButtonType="ImageButton" CommandName="Delete" ItemStyle-HorizontalAlign="Center" ConfirmText="Removing Item"></telerik:GridButtonColumn>

</Columns>

<AlternatingItemStyle HorizontalAlign="Left" CssClass="disabledFontColorEmphasis"

Wrap="false" />

</MasterTableView>

</ClientSettings>

</telerik:RadGrid>
