[Solved] TriStateCheckBoxes without checking parent node

I am using the TriStateCheckBoxes so the user can easily see whether child nodes are selected under a parent node. The issue I have is that if a user checks all child nodes then the parent automatically becomes checked. Is there a way to keep the parent from becoming checked unless the user specifically checks that node?

Sys.WebForms.PageRequestManagerParserErrorException when Trace=true

Hi:

I'm using RadGrid for Ajax 2008Q3 release. I have a simple grid with sort enabled. When I have the page trace="false", everything works fine. However, when trace="true", then I get the Sys.WebForms.PageRequestManagerParserErrorException popup. Is there known issues with using trace when a page has ajaxified control? If so, how can one still trace the page event?

Thanks

Justin

Upload with Ajax

Hi everyone,
I have a scenario where I insert just the filename of the file I upload in the database. For this I upload a file to the server and retrieve the filename and then save the entity. But if I set the AjaxControlID="btnSave" I get en error saying object reference.
below is the code:

    
            <telerik:RadAjaxManager ID="RadAjaxManager1" runat="server" DefaultLoadingPanelID="LoadingPanel1">  
        
                    <AjaxSettings> 
        
                       <telerik:AjaxSetting AjaxControlID="btnSave">  
        
                          <UpdatedControls> 
        
                                <telerik:AjaxUpdatedControl ControlID="lblInfo" /> 
        
                          </UpdatedControls> 
        
                      </telerik:AjaxSetting> 
        
                    </AjaxSettings> 
        
            </telerik:RadAjaxManager>
 
<form id="form1" runat="server">

<asp:label id="lblInfo" runat="server"/>

            <
asp:FileUpload ID="image" runat="server" />
            
<asp:Button ID="btnSave" runat="server" Text="Save"
            
onclick="btnSave_Click" />

            </form>

and in the code behind I have the following:

    
            private String GetUploadImageName()  
        
                {  
        
                    if (image.PostedFile.ContentLength > 0)  
        
                    {  
        
                        //upload the file  
        
                        image.PostedFile.SaveAs(Server.MapPath("~\\Resources\\Images\\ExcerciseImages\\" +  
        
                                txtName.Text.ToString() + ".jpg"));  
        
                        return txtName.Text.ToString() + ".jpg";  
        
                    }  
        
                    else 
        
                    {  
        
                        return "";  
        
                    }  
        
                }

If anyone could help me point in the correct direction that be great.
Thanks

[Solved] ImageManager Upload Button Image Disappearing

I noticed that that background image used for the upload button in the imagemanager disappears after a file is selected to upload. All that remains is the text 'Upload' without the button image behind it. Is this a known issue?

Getting contents of controls inside NestedTableView

Hi,

I use the approach from this thread (http://www.telerik.com/community/forums/aspnet-ajax/grid/accessing-controls-inside-nestedtableview.aspx) to access the controls inside a NestedTableView and set their content on load. This works perfectly. One of the controls is a submit button. On click on this button I want to save the changes which have been made to the nested textboxes.

This is where the problem is. When I try to get the "Text" property of a textbox, I get it's old content. I guess this is because it gets overwritten duren the call of Page_PreRender().

What would be a proper way to get the contents of controls inside nested views?

Best regards,

Robert

Insert,update and delete grid items using form

I'm trying to insert, update and delete form data to a datagrid. I've seen examples for insert, update and delete when the grid is binded to the database. But I want an example where the grid gets its data from the form and perform update, insert and delete back to the page instead of the database. Are there any examples?

Also, some of my form controls are loaded based on combo box values i.e selected index changed

what value should be for "Get All" option in RadComboBox to show all records in RadGrid?

good day, guys,
I have a RadComboBox "RadComboBox_reject" with 2 options, "Rejected", and "Not Rejected", the value of "Rejected" is "true", the value of "Not Rejected" is "false", RadGrid is bound to sqldatasource, sqldatasource definition as following:

<asp:SqlDataSource ID="Sql_docket" runat="server"  SelectCommand ="SELECT DOCKET.DOCKETID ................... FilterExpression ="reject='{0}'" >
<FilterParameters>
    <asp:ControlParameter Name="reject" ControlID="RadComboBox_reject" PropertyName="SelectedValue" Type="Boolean"  ConvertEmptyStringToNull="true" />
</FilterParameters>
</asp:SqlDataSource>

Basically, my idea is to set "RadComboBox_reject" property "AutoPostback" = true, so that everytime user choose option from RadComboBox_reject, the selectedValue will be passed to sqldatasource by SqlDataSource  FilterParameters.

The above code is working fine. But, now, I am trying to add "Get All" option to "RadComboBox_reject", so that RadGrid will show all records when user select "Get All". My question is: what value should be for "Get All" option that will be passed to FilterParameters? Please note that FilterParameters type is "Boolean".

Thank you very much

Button Click Event with Button Inside DIV

I am using this script to put a Button INSIDE the Upload Div.

    
            <script type="text/javascript">  
        
            function pageLoad()  
        
            {  
        
               var upload = $find("<%= RadUpload1.ClientID %>");     
        
               var uploadDiv = upload.get_element();  
        
               var input = document.createElement("input");  
        
               input.type = "submit";  
        
               input.className = "ruButton";  
        
               input.value = "Upload My XML Now";  
        
               input.id = input.name = upload.getID("submit");  
        
               //the UL element of the upload  
        
               var ul = uploadDiv.getElementsByTagName("UL");  
        
               //the array of all LI elements of the UL element  
        
               var LIs = ul[0].getElementsByTagName("LI");  
        
               //Last LI item - the button area  
        
               var lastLi = LIs[LIs.length - 1];  
        
               lastLi.appendChild(input);     
        
            }  
        
            </script>

The file is being uploaded properly, however I need to be able to rename the file when it is uploaded as well as store the file path in the database.

How do I do a Button_Click event when using this JavaScript created button?

Date & Time Picker

Hi,

I am using RadDateTimePicker for which i am not able to link images from the calendar folder like arrorRight.gif, fastNavRight.gif, arrowLeft.gif and fastNavLeft.gif.

I have taken th following from :http://www.telerik.com/help/aspnet-ajax/calendar_appearanceskins.html
Set the ImagesPath property to specify the location the the navigation images in the titlebar. RadCalendar will look for the following images in the specified location: arrorRight.gif, fastNavRight.gif, arrowLeft.gif and fastNavLeft.gif. Alternatively to using ImagesPath, you can set the location of each image separately.

How do I set ImagesPath from css file.

Thanks in advance
