HierarchyLoadMode="ServerOnDemand" is working good except the first time expanding of any of the detailTables

Although this property is set to HierarchyLoadMode="ServerOnDemand" it behaves like some mixed mode.

Actually, everything is work just as should be work by documentation, but when I expand for the first time any of child levels, grid tries to Bind all the child tables.

I have considered this in SqlProfiler, when you expand some level but only for the very first time, you can see database calls for every parent row.

If it can help you in answering my problem I have used SessionDataSource.

Thanks in advance.

RadGrid in radwindow

Hi ,

I am using a radgrid in a radwindow,i am populating the grid dynamically code given below.

Now i want to select a grid row and pass some values in the rows to the parent page as i am using radwindow.
Radwindow is containing for E.g. SaveParameters.aspx page
Now when i click on grid row i want to pass a value in the row to parent page i.e MyReports.aspx
Only Select Column is in MasterTableView as this

    
            <MasterTableView>   
        
            <Columns>   
        
                    <telerik:GridButtonColumn ButtonType="LinkButton" Text="Select"   CommandName="Select">   
        
                    </telerik:GridButtonColumn>   
        
            </Columns>    
        
            </MasterTableView>

How can i do this as i am binding everything(columns also) dynamically?

    
             for(int i=0;i<=dstParam.Tables[0].Rows.Count-1;i++)  
        
                        {

RadTreeNodeCollection

I have a navigational RadTreeView which is built based on various DB calls for each branch, and was thinking it would be ideal if I could build them once, and then stick RadTree.Nodes into a cache object, which I can later re-use without needing to hit the database again.

Unfortunately RadTree.Nodes is Get only, and doesn't allow me to write the cached NodeCollection back to the Tree on the next load.

Is there any way to do something like this?

Pager not displaying on initial page load

On every RadGrid in my web application, I am having an issue where the pager is not displaying on the initial page load. After doing a post back, and rebinding the data, the pager shows up. Code for one of my grids is below:

    
            <telerik:RadGrid ID="RadGrid1" runat="server" AutoGenerateColumns="False"  
        
                        DataSourceID="SqlDataSource1" GridLines="None" AllowPaging="True"  
        
                        Skin="Black"> 
        
                        <MasterTableView DataSourceID="SqlDataSource1" PageSize="15"> 
        
                        <RowIndicatorColumn> 
        
                        <HeaderStyle Width="20px"></HeaderStyle> 
        
                        </RowIndicatorColumn> 
        
                        <ExpandCollapseColumn> 
        
                        <HeaderStyle Width="20px"></HeaderStyle> 
        
                        </ExpandCollapseColumn> 
        
                            <Columns> 
        
                                <telerik:GridBoundColumn DataField="Name" HeaderText="Name"  
        
                                    SortExpression="Name" UniqueName="columnName"> 
        
                                </telerik:GridBoundColumn> 
        
                                <telerik:GridBoundColumn DataField="Address1" HeaderText="Address1"  
        
                                    SortExpression="Address1" UniqueName="columnAddress1"> 
        
                                </telerik:GridBoundColumn> 
        
                                <telerik:GridBoundColumn DataField="Address2" HeaderText="Address2"  
        
                                    SortExpression="Address2" UniqueName="columnAddress2"> 
        
                                </telerik:GridBoundColumn>

                                    SortExpression="City" UniqueName="columnCity"> 
        
                                </telerik:GridBoundColumn> 
        
                                <telerik:GridBoundColumn DataField="State" HeaderText="State"  
        
                                    SortExpression="State" UniqueName="columnState"> 
        
                                </telerik:GridBoundColumn> 
        
                                <telerik:GridBoundColumn DataField="Zip" HeaderText="Zip"  
        
                                    SortExpression="Zip" UniqueName="columnZip"> 
        
                                </telerik:GridBoundColumn> 
        
                                <telerik:GridBoundColumn DataField="Phone" HeaderText="Phone"  
        
                                    SortExpression="Phone" UniqueName="columnPhone"> 
        
                                </telerik:GridBoundColumn> 
        
                            </Columns> 
        
                            <PagerStyle Mode="NumericPages" /> 
        
                        </MasterTableView> 
        
                    </telerik:RadGrid> 
        
                    <asp:SqlDataSource ID="SqlDataSource1" 
        
                        ConnectionString="<%$ ConnectionStrings:TLRGCPortal %>" 
        
                        ProviderName="System.Data.SqlClient" SelectCommand="spGetLocations"  
        
                        runat="server" SelectCommandType="StoredProcedure"></asp:SqlDataSource>

An example of a rebinding that makes the pager display is below:

    
                    protected void btnClear_Click(object sender, EventArgs e) 
        
                    { 
        
                        txtSearch.Text = ""; 
        
                        SqlDataSource1.SelectCommand = "spGetEmployeeDirectory"; 
        
                        SqlDataSource1.SelectCommandType =  SqlDataSourceCommandType.StoredProcedure; 
        
                        SqlDataSource1.SelectParameters.Clear(); 
        
                        SqlDataSource1.DataBind(); 
        
                    }

Does anyone have an idea as to what might be causing this? It is happening on every single RadGrid in my application. As I didn't have much data in the database through development, I never noticed the issue before. Now that we are beginning to populate, it is becoming a problem. Thank you for any help you can provide

Customizing iCal Export

Hello,

I think I saw in an earlier thread that the current export functions don't allow you to specify things like the location and a description. There was a mention in there that it would be forwarded to the request to do so to the development team - I was wondering if anybody knows if that's still in process, or if there's a work-around other than writing my own export function...

Thanks,

Mike

URGENT : Unselect checkbox on client side not working

Hi,

If I execute this code in the OnCommand client-side event :

var elems = sender.get_masterTableView().get_dataItems();
for(var i=0;i<elems.length;i++)
{
elems[i].set_selected(false);
}

or this code : sender.get_masterTableView().clearSelectedItems()

it seems to unselect the dataitem in memory but not uncheck the checkbox html control.

If i get the html checkbox with get_element() and I unselect him, I also have a problem when the user want to click a chekbox previously selected on a other page : he need to click twice on an unchecked checkbox to check ...

Is there a way to simple solve this problem ?

I need to clear all checked checkbox when paging (full ajax), and keep the item checked in memory. When the user return on a page where checkbox are previously checked, I need to check them automatically.

thanks for you help !

        </div> 

    </form> 

</body> 

</html>

The codebehind:

using System;  

using System.Data;  

using System.Configuration;  

using System.Collections;  

using System.Web;  

using System.Web.Security;  

using System.Web.UI;  

using System.Web.UI.WebControls;  

using System.Web.UI.WebControls.WebParts;  

using System.Web.UI.HtmlControls;  

public partial class Portal : System.Web.UI.Page  

{  

    protected void Page_Load(object sender, EventArgs e)  

    {  

        //  

    }  

    protected void HideButton_Click(object sender, EventArgs e)  

    {  

        RightColumnTD.Visible = false;  

    }  

}

Then I drag "Control3" to the left column and drop it into the "LeftZoneRadDockZone" zone. When I click on the "HideButton" afterwards, an System.ArgumentException is raised: "Script control 'Control3RadDock' is not a registered script control. Script controls must be registered using RegisterScriptControl() before calling RegisterScriptDescriptors(). Parameter name: scriptControl".

Please advice on this.

Kind Regards,
