Hi Friends,

I am very new to Telerik control.

I have a task to populate two radgrids. the scenario is

1) On load the first grid say (RoomGrid) populates Room names of a school ie from 1 to 10 with Id, Roomname and Description

1-Room1-Descritpion1
2-Room2-Description2
.
.
.10-Room10-Description

So when I click on a particular row the second grid say studGrid should be populated with StudId, StudName in that room.

I dont want postback to happen when I click on the row as i will be opening a radwindow on doubleclicking RoomGrid.

So If I use selectedIndexChanged event the page will reload(postback) and doubleclick fails.

Can anyone help me how to do this? or any sample code? Very urgent Please

Thanks in Advance
Balaji

[Solved] RadGrid and NeedDataSource

hi

I have a grid with paging enabled and viewstate is set to True and i have set a breakpoint at the NeedDdataSource. What happened is that whenever i click the page number on the grid it goes into breakpoint and it would ran through the code again.

There is some performance issues here if i have many rows of records.

Since i know the dataset has been filled with data, how do i code it so that there is no need to go through that code everytime i do a paging on the grid? thanks and sorry for the inconvenience caused.

Protected Sub RadGrid1_NeedDataSource(ByVal source As Object, ByVal e As GridNeedDataSourceEventArgs) Handles RadGrid1.NeedDataSource

Dim ds1 As New DataSet
ds1 = dsDemo("demo","demo")
RadGrid1.DataSource = ds1.Tables(0).DefaultView

End Sub

[Solved] Two Q: Is there a Filter Event?

Hi

Question1: I was under impression that Grid control by default used Ajax features, and any action on grid will produce ajax like behaviour as seen in demos. but I observe that it does postbacks. what i am missing.

Question2: I am using following code in Page_Load Event to bind datasouce to grid,

if (!Page.IsPostBack)

{

MembershipUserCollection uc = Membership.GetAllUsers();

RadGrid1.DataSource = uc;

RadGrid1.DataBind();

}

Then while running code, when I select filter the grid goes blank. I understnad that on postback DataSource is lost, so
1. Is there a filter event where i can assing DataSource back to grid.
2. I would prefer, if there is a way to do filter at client-side itself.

Regards

RadTab Multipage issue when set to invisible/visible

Hi, I have a RadTab, and a Multipage that are generated Dinamically. When I call the function, GeneraInfoGeneral for the firs time works fine, but when another control sets the RadTab to visible=false; and the RadMultipage to visible=false, it only persists the pageView (visible), if I dont change between tabs.

When I first click on btnInfoGral it works fine, but after I click btnServidorPublico and I clear tabs and clear pageViews, the pageview does not load until I click another tab. Im trying to set RadTab visible and invisible as its Multipage and pagesviews too.

Auto expand not working in 1680 x 1050

Whenever we change the display resolution and refresh the screen the grid seemlessly fits the entire screen. But if the resolution is changed to 1680 x 1050 it is not happening!

Any workaround possible?!

Thank you

Slider layout options, disable close icon?

I removed the dock icon with the EnableDock property set to false.

1. How can I disable the close icon?
2. how can I set the height of the slider that expands to be exactly large enough to fit the content that is there. The content is dynamic so it won't be the same each time so I can't set a fixed height.

Workflow Data Entry Using PanelBar

Masters and Experts,
I would like to implement a workflow form using the PanelBar control. I wanted to check here and see if it's possible before I put the development effort into it. What I would like to accomplish is creating a user control that would display in a RadWindow that will function as follows;
Panel1:
User Selected Search Criteria
Search / Move Next button (if results were found, If not message user)
Panel2
RadGrid containing the results from the Search from Panel1. User would select the record they need for primer data for their new entry on Panel3
Move Next Button
Panel3
ReadOnly data items from Panel2s selection and editable user entry data fields
Save Button

If it's possible for the control to handle that type of data manipulation would you know of any samples I could review as reference.

Thanks,
Tim

[Solved] Change text of custom linkbutton in CommandItemTemplate

I have the following in the CommandItemTemplate tag:

<
 
CommandItemTemplate>
 
    <table width="100%">
 
        <tr>
 
            <td align="left">Third Party Mismatches</td>
 
            <td align="right">
 
                <asp:LinkButton ID="showFilter" runat="server" CommandName="DisplayFilter"
 
                    Text="Filter">
 
                </asp:LinkButton>
 
            </td>
 
        </tr>
 
    </table>
 
</
 
CommandItemTemplate>

 
What i want to do is when the user clicks on the showFilter link it will display or hide the folter depending on if it is shown already or not. I have that part working. What I can't get is to change the text to "Show Filter" if the filter is hidden and "Hide Filter" if it is shown.

I have the followinfg code but it isn't working.

            Protected Sub GrdThirdParty_ItemCommand(ByVal source As Object, _  
        
                                     ByVal e As GridCommandEventArgs) _  
        
                                     Handles GrdThirdParty.ItemCommand  
        
                    If e.CommandName = "DisplayFilter" Then 
        
                        Dim lnkButton As LinkButton = CType(e.Item.FindControl("showFilter"), LinkButton)  
        
                        If GrdThirdParty.AllowFilteringByColumn = False Then 
        
                            GrdThirdParty.AllowFilteringByColumn = True 
        
                            lnkButton.Text = "Hide Filter"  
        
                        Else 
        
                            GrdThirdParty.AllowFilteringByColumn = False 
        
                            lnkButton.Text = "Show Filter" 
        
                        End If 
        
                        GrdThirdParty.MasterTableView.Rebind()  
        
                    End If 
        
                End Sub 
        
Any ideas?

Thanks for the help.
