Hi

for (int i = 0; i < RadTreeView1.Nodes.Count; i++)

{

bool bchk= RadTreeView1.Nodes[i].Checked;

}
Response.Redirect("WebForm1.aspx");

I have treeview control with checkbox.
I selected some nodes and click on save button at the time i can able to get all the checked nodes.But when i come back to the same page using click on browser back button at the time i can not get the checked node in button click event. all the nodes are returning false only .But in the UI its seems to be selected only.what i needs to do?

I am using IE 7.0 and
Telerik .Web.UI 2008.1.415.20

[Solved] RadGrid : Exiting insertMode in Hierarchical grid

Scheduler height and Month View

Hi,

I have a simple implementation of RadScheduler on a Page and have it set to width=100%, height=100%, OverflowBehaviour=Expand.

The scheduler fills the page area when using the Daily, Weekly or Timeline views, but is smaller than the area when the Month view is selected. I am particularly using this implementation as a Monthly Calendar, and need to fill the available space.

I have looked through the Forums and found a couple of possible solutions but none seem to work quite as expected.

I am using the latest Q3 2008 release build 2008.3.1210.20

Sorting grid doesn't reset TargetControls

I've been using this article as a guide to implement mouseover "details" tooltips in my RadGrid. The result has been great - in general it works beautifully. There are, however, a couple issues that I could use some help with:

If the user sorts the RadGrid, it should clear the TargetControls property of the RadToolTipManager and re-populate that with the new values for each target control. That doesn't happen. I'v implemented the code mentioned in the article in my ItemCommand and ItemDataBound but after a sort the value for each TargetControl is still the old one.
I've tried changing the Skin value of the RadTooltipManager, but it doesn't seem to make any difference. Any idea what I might be missing?
I'd like to move the "Close" button to the left side of the tooltip, is there a way to control it's position, or anything else about the close button?

Here is the code I'm using:

    
            protected void RadGrid1_ItemCommand(object sender, GridCommandEventArgs e)  
        
            {  
        
                if (e.CommandName == "Sort" || e.CommandName == "Page")  
        
                    RadToolTipManager1.TargetControls.Clear();  
        
            }  
        
            protected void OnAjaxUpdate(object sender, ToolTipUpdateEventArgs args)  
        
            {  
        
                UpdateToolTip(args.Value, args.UpdatePanel);  
        
            }  
        
            private void UpdateToolTip(string elementID, UpdatePanel panel)  
        
            {  
        
                var ctrl = Page.LoadControl("~/usercontrols/PersonSummary.ascx");  
        
                panel.ContentTemplateContainer.Controls.Add(ctrl);  
        
                var details = (PersonSummary)ctrl;  
        
                details.xref = elementID;  
        
            }  
        
            protected void RadGrid_ItemDataBound(object sender, GridItemEventArgs e)  
        
            {  
        
                if (e.Item.ItemType != GridItemType.Item && e.Item.ItemType != GridItemType.AlternatingItem) return;  
        
                var target = e.Item.FindControl("targetControl");  
        
                if (!Equals(target, null))  
        
                    if (!Equals(RadToolTipManager1, null))  
        
                    {  
        
                        var currentRow = e.Item as GridDataItem;  
        
                        if (currentRow != null)  
        
                            RadToolTipManager1.TargetControls.Add(target.ClientID, currentRow["colXref"].Text, true);  
        
                    }  
        
            }

Obviously I removed a lot of extraneous code to focus on just the bits that pertain to this question...
Thanks for the help!

[Solved] RadConfirmInGridWithAjax.zip not work in RadWindow

Hi, All
I had seen http://www.telerik.com/support/kb/aspnet-ajax/grid/replacing-the-default-confirm-dialog-for-radgrid-with-radwindow-confirm.aspx and tried RadConfirmInGridWithAjax.zip . It works.
However, If the aspx page was displayed in RadWindow, radAjaxManagerObject= undefined

PageRequestManagerParserErrorException

Hi All,

We are preparing an application for parts lookup. We are using telerik rad ASP.NET AJAX Q1 Controls in our application.

Whenever the postback is happening, i am getting the below mentioned error. This is not happening everytime, its coming at times and the whole functionality of application is getting disturbed.

Please help me to solve this error.

Line: 4723

Error: Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed. Common causes for this error are when the response is modified by calls to Response.Write(), response filters, HttpModules, or server trace is enabled.

On demand webservice load not working on ComboBox

I just upgraded my VS to framework 3.5. I had an application that I converted w/out any errors and it no longer loads the combobox on demand. It says it can't find the method being called. I ran it through debug and it never even goes to the webservice.

<telerik:RadComboBox ID="cmboDept" runat="server" AutoPostBack="true"

EnableLoadOnDemand="true">

<WebServiceSettings Method="loadDepartment"

Path="~/WebServices/srvc_ComboBox.asmx" />

</telerik:RadComboBox>

This worked just find in VS 2003. Any idea what I may be missing?

Thanks!

Question about DataBinding with DataSet...

I have the following RadTreeView set up like this:

    
            <telerik:RadTreeView ID="radtree" runat="server" Skin="Default">  
        
                <Nodes> 
        
                    <telerik:RadTreeNode runat="server" Expanded="True" Text="Level_1">  
        
                        <Nodes> 
        
                            <telerik:RadTreeNode runat="server" Expanded="True" Text="Level_2">  
        
                                <Nodes> 
        
                                    <telerik:RadTreeNode runat="server" Expanded="True" Text="Level_3">  
        
                                        <Nodes> 
        
                                            <telerik:RadTreeNode runat="server" Expanded="True" Text="Level_4">  
        
                                                <Nodes> 
        
                                                    <telerik:RadTreeNode runat="server" Expanded="True" Text="Level_5">  
        
                                                        <Nodes> 
        
                                                            <telerik:RadTreeNode runat="server" Expanded="True" Text="Level_6">  
        
                                                                <Nodes> 
        
                                                                    <telerik:RadTreeNode runat="server" Expanded="True" Text="Level_7">  
        
                                                                    </telerik:RadTreeNode> 
        
                                                                </Nodes> 
        
                                                            </telerik:RadTreeNode> 
        
                                                        </Nodes> 
        
                                                    </telerik:RadTreeNode> 
        
                                                </Nodes> 
        
                                            </telerik:RadTreeNode> 
        
                                        </Nodes> 
        
                                    </telerik:RadTreeNode> 
        
                                </Nodes> 
        
                            </telerik:RadTreeNode> 
        
                        </Nodes> 
        
                    </telerik:RadTreeNode> 
        
                </Nodes> 
        
                <CollapseAnimation Duration="100" Type="OutQuint" /> 
        
                <ExpandAnimation Duration="100" /> 
        
            </telerik:RadTreeView>

I also have the following DataSet set up like this:

    
            DataSet oDS1 = null;  
        
            DbCommand dbCom = db.GetStoredProcCommand("SQL Code");  
        
            oDS1 = db.ExecuteDataSet(dbCom);  
        
            oDS1.Relations.Add(new DataRelation("Table0ToTable1", oDS1.Tables[0].Columns[0], oDS1.Tables[1].Columns[3], false));  
        
            oDS1.Relations.Add(new DataRelation("Table1ToTable2", oDS1.Tables[1].Columns[0], oDS1.Tables[2].Columns[3], false));  
        
            oDS1.Relations.Add(new DataRelation("Table2ToTable3", oDS1.Tables[2].Columns[0], oDS1.Tables[3].Columns[3], false));

If I wanna bind oDS1 to a RadTreeView like this:

    
            radTree.DataSource = oDS1;  
        
            radTree.DataBind();

What event do I need to access to be able to say something like:
'all rows in Table[3] need to add nodes at level_7'.
