Find the parent of the parent in hierarchy grid

Hi,

I want to find the parent of the parent in a hierarchy grid structure. I have this:

<telerik:RadGrid ID="RadGrid1" runat="server" Width="50%" ShowStatusBar="true" AutoGenerateColumns="False"

PageSize="50" AllowSorting="True" AllowMultiRowSelection="False" AllowPaging="True"

OnDetailTableDataBind="RadGrid1_DetailTableDataBind" OnNeedDataSource="RadGrid1_NeedDataSource"

OnPreRender="RadGrid1_PreRender">

<PagerStyle Mode="NumericPages"></PagerStyle>

<MasterTableView Width="100%" DataKeyNames="ServiceName" AllowMultiColumnSorting="True">

<DetailTables>

<telerik:GridTableView DataKeyNames="MethodName" Name="MethodName" Width="100%">

<DetailTables>

<telerik:GridTableView DataKeyNames="ParameterName" Name="ParameterName" Width="100%">

<Columns>

<telerik:GridBoundColumn SortExpression="ParameterName" HeaderText="Parameter Name"

HeaderButtonType="TextButton" DataField="ParameterName">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn SortExpression="ParameterType" HeaderText="Parameter Type"

HeaderButtonType="TextButton" DataField="ParameterType">

</telerik:GridBoundColumn>

<telerik:GridTemplateColumn HeaderText="Parameter Value" UniqueName="ParamWrapper">

<ItemTemplate>

<asp:TextBox runat="server" ID="ParameterValue" Text='<%# DataBinder.Eval(Container.DataItem, "ParameterValue") %>'></asp:TextBox>

</ItemTemplate>

</telerik:GridTemplateColumn>

</Columns>

</telerik:GridTableView>

</DetailTables>

<Columns>

<telerik:GridBoundColumn SortExpression="MethodName" HeaderText="Method Name" HeaderButtonType="TextButton"

DataField="MethodName" UniqueName="MethodName">

</telerik:GridBoundColumn>

<telerik:GridTemplateColumn HeaderText="Status">

<ItemTemplate>

<asp:Button runat="server" ID="btnMethodStatus" OnClick="btnMethodStatus_OnClick"

Text="-"></asp:Button>

</ItemTemplate>

</telerik:GridTemplateColumn>

<telerik:GridTemplateColumn HeaderText="Elapsed time">

<ItemTemplate>

<asp:Label runat="server" ID="lblElapsedTime" Text="0">

</asp:Label>

</ItemTemplate>

</telerik:GridTemplateColumn>

<telerik:GridTemplateColumn HeaderText="Last executed on">

<ItemTemplate>

<asp:Label runat="server" ID="lblLastTimeExecuted" Text="-">

</asp:Label>

</ItemTemplate>

</telerik:GridTemplateColumn>

</Columns>

</telerik:GridTableView>

</DetailTables>

<Columns>

<telerik:GridBoundColumn SortExpression="ServiceName" HeaderText="Service Name" HeaderButtonType="TextButton"

DataField="ServiceName">

</telerik:GridBoundColumn>

<telerik:GridTemplateColumn HeaderText="Status">

<ItemTemplate>

<asp:Button runat="server" ID="btnServiceStatus" OnClick="btnServiceStatus_OnClick"

Text="-"></asp:Button>

</ItemTemplate>

</telerik:GridTemplateColumn>

<telerik:GridTemplateColumn HeaderText="Elapsed time">

<ItemTemplate>

<asp:Label runat="server" ID="lblElapsedTime" Text="0">

</asp:Label>

</ItemTemplate>

</telerik:GridTemplateColumn>

<telerik:GridTemplateColumn HeaderText="Last executed on">

<ItemTemplate>

<asp:Label runat="server" ID="lblLastTimeExecuted" Text="-">

</asp:Label>

</ItemTemplate>

</telerik:GridTemplateColumn>

</Columns>

</MasterTableView>

</telerik:RadGrid>

Code behind:

protected void RadGrid1_DetailTableDataBind(object source, Telerik.Web.UI.GridDetailTableDataBindEventArgs e)

{

GridDataItem dataItem = (GridDataItem)e.DetailTableView.ParentItem;

switch (e.DetailTableView.Name)

{

case "MethodName":

{

e.DetailTableView.DataSource = Method.GetMethods((string)dataItem.GetDataKeyValue("ServiceName"));

break;

}

case "ParameterName":

{

//TODO: Get ParentItem

e.DetailTableView.DataSource = Parameter.GetParameters((string)dataItem.GetDataKeyValue("MethodName"), (string)parentItem.GetDataKeyValue("ServiceName"));

break;

}

}

In the case "ParamenterName", I need to be able to find the parent of the parent of the EventArgs e. Right now I can easily get the immediate parent, what I need is one step above.

Thanks in advance,

Grid

Input Controls not updating value for postback

I have a support ticket open for this (380752), but I thought I would give the forums a shot as well. The web application I am working on is for an annual review at my company. At the top of the form there is a standard ASP.NET drop down box with a list of names that the person logged into the website manages. They can select the person from the drop down box and on the server side, it will check to see if that use already has an annual review in the database or not. If not, it will display a blank form for the person to fill out and submit to the database.

If there is already one in the database, it will pull the information from the database and populate the many RadTextBoxes and RadNumericTextBoxes I have on the form with the information from the database. This is so they can update it or make changes before the final submission to the employee. That all works fine up to this point. The issue comes in when I try to change a value on the form that was populated with data from the database. If I try to change a rating on one of the RadNumericTextBoxes or change the comments or any change with any of the RadInput controls, when I hit the save button, on the watch list, the values are exactly as they were initially populated from the database and not the changed values I typed in the browser. I am testing this on IE 9.0.7930 and I have also tested it on Firefox 3.6.13 to make sure it was not an IE issue.

Any ideas on what I may be doing wrong?

Thanks.

Radgrid paging w. multiple grids in Usercontrols

Hi All,
I have an Ajax-ified page with six RadGrids. To avoid duplicate code the grid is in a usercontrol that get's loaded into six panels. The datasource for each grid is handled in the "main" page in code-behind.
Everything's working, except for paging. I believe I need to handle the NeedDataSource event, but I'm unsure where to do this.
Thx in advance for help and/or pointers!
Rgds - M.

Pseudocode (code behind)

// SqlConnection sqlconn = ......

// Dataset, fill etc ...

// Findcontrol grid in pnl1

grid1.Datasource = ds.Tables[0];

grid1.DataBind();

// Findcontrol grid in pnl2

grid2.Datasource = ds.Tables[1];

grid2.DataBind();

//etc

Pseudocode (aspx)

<telerik:RadAjaxManager ID="RadAjaxManagerProxy1" runat="server">

<AjaxSettings>

<telerik:AjaxSetting AjaxControlID="Execute">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="pnl1" />

<telerik:AjaxUpdatedControl ControlID="pnl2" />

<telerik:AjaxUpdatedControl ControlID="pnl3" />

.......

</UpdatedControls>

</telerik:AjaxSetting>

</telerik:RadAjaxManager>

<asp:Panel ID="pnl1" runat="server" Visible="false">

[Solved] RadWindow - Set Parent TextBox after event

Hi everyone

I want to create RadWindow to help a user enter a value of a textbox. So basically on a form I will have a RadTextBox and a button to show the RadWindow. The RadWindow will have a grid that is filterable with all the options the user can select. When he selects thes value, it needs to close the RadWindow and populate the Textbox with the selected value.

Are there any examples on this?

Thanks

RenderMode="Lightweight" Issues

Hi,

I wanted to take advantage of the lightweight rendermode, but when I set
RenderMode="Lightweight"
On RadWindow and RadWindow Manager controls, I notice that:

1. I lose my custom icon, it displays the default.
2. Pages that I open in RadWindows that have dynamic page titles (set in codebehind in pre init) do not show the custom title.

When I remove the RenderMode attribute, the issues go away.

Update:
RenderMode="Lightweight" is responsible for the icon not showing up.

But after removing the RenderMode, I'm still not seeing all my page titles.
That issue is being asked by myself and another user here:
http://www.telerik.com/community/forums/aspnet-ajax/window/title-isn-t-set-from-content.aspx

I am still losing my icon with RenderMode="Lightweight" (I've tried different image formats to no avail)

RenderMode="Lightweight" versus normal rendermode

When I add RenderMode="Lightweight" to a RadWindowManager, only the active RadWindow is fully visible.
All other open RadWindows are semi-transparent.

Without the RenderMode="Lightweight", the content of all RadWindows are fully visible. It's only the Titlebar and "window frame" of non-active windows that become semi-transparent.

I would like to keep RenderMode="Lightweight" but still have content of all windows fully visible.
I see an "Opacity" attribute, but it doesn't seem to do anything.

One of the main reasons to use multiple RadWindows is that users can compare the content of 2 or more windows,or one window has info that is pertinent/related to another window.

This becomes impossible when RenderMode="Lightweight" because only the active window can be fully seen.

Help!

Single vertical column of tiles

Is it possible, in this first version, to have a single vertical column of tiles?

E.g. I would like 5 'tiles' stacked vertically in a 1x5 grid layout.

I cannot find a way to stop the tiles being added horizontally.

The documentation http://www.telerik.com/help/aspnet-ajax/tilelist-tiles-overview.html states :
"Tiles are ordered in columns, where each subsequent tile from the control declaration is placed below the previous one." but this does not seem to be the case, each subsequent tile is placed to the right of the previous one.

I know this is the v1.0 of this control, but I'm confused.

thanks
