Example Detail is updated only after clicking refresh button

Hello
I have RadGrid Q3 2008 and using VB.Net
I have created a Status/Detail reporting system that uses the classic Master Detail Telerik example as seen at http://www.telerik.com/help/aspnet-ajax/grid-related-grids.html

Everything appears to work fine except when I click on a master row item the detail grid does not automatically update unless I click on the refresh button. I am using Ajax Manager. My datakeys appear to be correct since everything turns out correctly when I press the Refresh button.

PS. I do note that when I turn off Ajax for both grids then they update correctly.

I'm sure that I'm overlooking something.
Your help would be appreciated.

regards,

Ted

RadGrid not filtering properly

Hey peeps,

We have a RadGrid on a page that shows a list of all records in a specific table. With this, the user has selectable options for filtering the information in a seperate space above the Grid (not using the RadGrid filtering options - we are still using an older version of Telerik and the current set does not provide a checkboxlist which we require. The current filtering options does not provide the functionality we need to enable the filtering and besides this, the current options available will be too difficult for our users to understand.).

The user then makes his/her selection from the available filtering options (on the coding side, I programmatically create the SQL query needed to retrieve records according to the selection). This query is then assigned to the SqlDataSource (SqlDataSource1.SelectCommand = 'query'). When the user clicks the Filter button, the RadGrid populates with the results from the new custom query. HOWEVER, when I click on the next page or click on any other page number, the Grid populates from scratch and does not keep the filtering. I have tried to use the FilterExpression on the SqlDataSource, the same happens. First page shows the filtered results but when moving to the next or previous page, the data is "reset".

How can I have the Grid reflect ONLY the data obtained from the new query?

Ajax docked user control

Hi,

I have a main page with a RadAjaxManager on it, 2 dock zones and docks within those zones. The docks contain Web User Controls, whose ID's are known and no new Controls will be dynamically added. Each of these docks have a DockCommand that open up a RadWindow. What I am trying to achieve is that once the RadWindow closes or the save button in the RadWindow is clicked (effectively closing the window anyway) the UserControl in the dock that the RadWindow was opened from needs to rebind.

Any help with this please?

Thanks
Marcel

Chart Axis clipping

Hi,

For various reasons I can't use the nice GUI designer, so I'm trying to format the chart via codebehind, but I'm having two issues I can't seem to solve.

1. The YAxis (the names in the image), is clipping, I can't figure out how to fix that. Note that this is a custom Axis - AutoScale = false.
2. There is a large space between the legend and the actual chart, I can't seem to figure out which property to set to fix this.

Problems with controlparameters using GridDropDownColumns in RadGrid

I have a Radgrid which displays a recordset with a lot of foreign key relations returned. Most of the values are the IDs of the rows, so I want to display the related descriptions from the lookup tables. To this I am using several GridDropDownColumns.
All of them work correctly with their respective sqldatasource bindings except the one that is dependent on another GridDropDownColumn. It seems that if I use the first dropdown as a <asp:controlpatameter... for the sqldatasource of the second dropdown ...then the Page Load cannot find the first dropdown.
Here is the sqldatasource for the second dropdown:

<asp:SqlDataSource ID="ds_DemoValues" runat="server" ConnectionString="<%$ ConnectionStrings:CFSubsConn %>"<br><br

>SelectCommand="SELECT [ID], [QuestionID], [Value] FROM [v_DemoValues] WHERE ([QuestionID] = @QuestionID) UNION SELECT Null AS ID, '' as QuestionID, 'Select a Value' AS [Value]"><

br><br><SelectParameters> <br><br><asp:controlparameter name="QuestionID" controlid="ddl_ParentControlID" propertyname="SelectedValue"/> <br><br></SelectParameters><br><br></asp:SqlDataSource>

The error on PageLoad is:

Could not find control 'ddl_ParentControlID' in ControlParameter 'QuestionID'.

The RadGrid code is as follows:

<telerik:RadGrid ID="RadGrid1" AutoGenerateColumns="False" runat="server" Width=750px DataSourceID="ds_Validation" GridLines="None"

Very little happens in the code-behind. I have tried some default value manipulation there, but it seems it only works on either the PageLoad or Add Record or Edit..... but never all three.

Please help.

Issues with RadWindow titlebar

Hi there,

Im currently using the radTools Q3 2011 Rad window and I'm having issues when it renders its titlebar (with the default skin).

<telerik:RadWindowManager ID="RadWindows" runat="server">

<Windows>

<telerik:RadWindow ID="RadActionWindow" RegisterWithScriptManager="false" OnClientClose="updateRadGrid" runat="server" CssClass="actionWindow" AutoSize="true" Modal="true" VisibleStatusbar="False" VisibleTitlebar="true" EnableTheming="True" EnableEmbeddedSkins="True" DestroyOnClose="false" ReloadOnShow="true" ShowContentDuringLoad="false">

</telerik:RadWindow>

</Windows>

</telerik:RadWindowManager>

The problem is that the title bar sets its title row too high, I have tried the following:

1. Remove the reset.css in case there was some kind of conflict.
2. Set up a blank window with no content - still get the same issue.

I have included an image to better explain what I mean

Thanks for your time

Issues with RadGrid inside RadWindow

Hi,

I have few problems with RadGrid inside a RadWindow.

1) In that RadGrid, I have AllowFiltering as true. Now, when I am on some other page and try to filter the grid, I go back to first page...

2) When I do any operations on RadGrid, the RadWindow automatically closes.

Please help because everything works fine in RadGrid which is not inside RadWindow.

RadControls compatibility

Hi,
We are using radajaxcontrols 2007 version. Now we are facing some issues with controls like radeditor and RadMaskedTextBox in IE9. From the forums I came to know that these issues are fixed in recent versions. Right now I cannot upgrade complete radcontrols in my project which will take more time for testing. So I would like to upgrade only those two controls. But when I download the latest radajaxcontrols and install them, I got only one dll(telerik.web.ui). I need individual DLLs for those two controls as we had in the older version. Can anyone help me on this?

Thanks,
Jawahar
