I have this function on my aspx page.
function openWindow() {

            //get a reference to the window
            var oWnd = $find("<%= RadWindow2.ClientID %>");
            //set its NavigateUrl
            oWnd.setUrl("http://xyz.com/abc.zip");
            //add the name of the function to be executed when RadWindow is closed

            //show the window
            oWnd.show();
        }
I want to call this function in Button click event through RegisterStartupScript. It gets called but window doesn't open. Also I want to open a url which has a zip file for download. So as soon as user is prompted about Save dialog box, I want to close radwindow.

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>

Open menu on click AND mouseover

Hi,

i know there is a setting ClickToOpen setting to allow you to choose BETWEEN the menu opening on a click, or when the mouse goes over it.

I however would like the menu to open for BOTH a click and mouse over. th reason being that we have an intranet application that we are going to be sharing out onto the internet. Our main users will be using full IE and like the menu opening when the mouse overs. Our remote users will be using iphones and cannot use the mouse over, so the idea solution is to have both modes enabled.

Is this possible?
