Design Question

Hello All,

I am new to Telerik and I have a some what of a general (desing) question that has been bothering me for a while.

Master/Content page. . . or...
Single Page with IFrame

I am trying to find a design that will have a Treview (serving as a menu) on the left hand side and content on the right hand side. Very similar to how 'SmarterMail' (http://www.smartertools.com/smartermail/mail-server-software.aspx) does it. I have done this in the past using both Master/Content pages as well as Single Page with an IFrame to load other pages.

I find the (Single Page with an IFrame to load other pages) simpler however some browsers don't like the IFrame and I have a love hate relationship with Master/Content pages.

Do you have any suggestions or other design guidelines for doing this?

Thanks

FindNodeByValue then Nodes.Add a child?

I've used a SQL CTE to build a table that represents my hierarchy and now I'm trying to loop through those records to find the parent node, create a new node object and then append that new node object as a child of the parent node I found.

I've got a radtreeview with a parent node with a value of 0. I've tried accomplishing this two ways - neither works.

The following compiles without error, but doesn't add the newly created CurrentNode to the node I found in objMyTreeView.
objMyTreeView.FindNodeByValue("0").Nodes.Add(CurrentNode);

The following will find the parent node, but when I add the CurrentNode to it - I'm adding it to the ParentNode object - not the actual parent node in objMyTreeView.
RadTreeNode ParentNode = objMyTreeView.FindNodeByValue("0");
ParentNode.Nodes.Add(CurrentNode);

This seems like it should be simple - find the node with the value of the current node's parent, then add my current node as a child of the found node. Any advice offered would be appreciated. I must be overlooking something obvious.

In the above code if you click on "Text1" you will see that error. This error comes only when i try to run this on IPAD for all other OS's it is working fine. Can you please let me know where I am going wrong. The error only comes when i include the RadPanelBar within the RadSplitter. If if run it alone this error does not come. Can you please let me know the reason behind this I am unable to debug this issue.

Dynamically Generate RadContextMenu from SQL Server Table using Cell Value of the RadGrid (on which the user clicked to get the Context Menu) as a parameter

Hi,

I'm trying to Dynamically generate the RadContextMenu based on the contents of the Cell in RadGrid on which the user clicks. The menu items are stored in the SQL Sever database. Below is my client side code :

function RowContextMenu(sender, eventArgs) {

var evt = eventArgs.get_domEvent();

if (evt.target.tagName == "INPUT" || evt.target.tagName == "A") {

return;

}

var index = eventArgs.get_itemIndexHierarchical();

var row = sender.get_masterTableView().get_dataItems()[index];

var current_status = sender.get_masterTableView().getCellByColumnUniqueName(row, "Current_Status").innerHTML;

var

process_status = sender.get_masterTableView().getCellByColumnUniqueName(row, sender.get_masterTableView().get_columns()[evt.target.cellIndex].get_uniqueName()).innerHTML;


                var process_area = //write code to get the column header of the selected cell

document.getElementById("radGridClickedRowIndex").value = index;

sender.get_masterTableView().selectItem(row.get_element(), true);

var menu = $find("<%=RadMenu1.ClientID %>");

menu.show(evt);

evt.cancelBubble = true;

evt.returnValue = false;

if (evt.stopPropagation) {

evt.stopPropagation();

evt.preventDefault();

}

Now i want to pass the values current_Status, process_status and process_area to SQL server and get the list of actions to populate in the context menu.

Below are some snippets of the ASPX code:

<asp:SqlDataSource ID="ActionsDataSource" runat="server" ConnectionString="<%$ ConnectionStrings:MetadataCS %>"

ProviderName="<%$ ConnectionStrings:MetadataCS.ProviderName %>" SelectCommand="SELECT [Action] FROM [FileStatusActions] WHERE (([Process_Area] = @Process_Area) AND ([Current_Status] = @Current_Status) AND ([Process_Status] = @Process_Status))">

<SelectParameters>

<asp:Parameter Name="Process_Area" Type="String" />

<asp:Parameter Name="Current_Status" Type="String" />

<asp:Parameter Name="Process_Status" Type="String" />

</SelectParameters>

</asp:SqlDataSource>

<telerik:RadContextMenu ID="RadMenu1" runat="server" OnItemClick="RadMenu1_ItemClick" OnClientShowing="showContextMenu"

DataSourceID="ActionsDataSource" DataTextField="Action" DataValueField="Action" AppendDataBoundItems="true"

EnableRoundedCorners="true" EnableShadows="true">

<Items>

<telerik:RadMenuItem Text="Dynamic Menu" />

</Items>

</telerik:RadContextMenu>

Please help me achieve the desired functionality using either client side/server side code ? I am also willing to use XML files to load menu instead of database if feasible/possible.

Thanks,
Nishant

Ooops!:( An error has occurred! message

I am attempting to use the RadSocialShare control to allow users of my web site to tell others about the link. I have used the following code:

<telerik:RadSocialShare ID="RadSocialShare1" runat="server" CssClass="emailwrapper" Skin="Sitefinity" EnableEmbeddedSkins="true" >
<MainButtons>
<telerik:RadSocialButton SocialNetType="SendEmail" ToolTip="Email" CustomIconUrl="Images2/product/emailtofriend.png"/>
</MainButtons>
</telerik:RadSocialShare>

I am getting the following message when I attempt to send an email:

"Ooops!:( An error has occurred!"

I have got a section in my web.config for

<system.net>
    <mailSettings>
      <smtp from="customerservices@mywebaddress.com" deliveryMethod="Network">
        <network host="myisprelayserver.net" port="25" defaultCredentials="true" />
      </smtp>
    </mailSettings>
</system.net>

These settings work when I send mail in code using SmtpClient.Send() in another part of my application

Does anyone have any ideas why I might be getting this error?

Closing editForm from outside the Grid

Hello,

I have a button outside of the Grid which should close any opened insert and edit forms. For insert forms this works without any problem:

if (m_grid.MasterTableView.IsItemInserted)

{

GridEditFormInsertItem insertItem = (GridEditFormInsertItem)m_grid.MasterTableView.GetInsertItem();

insertItem.FireCommandEvent("PerformInsert", String.Empty);

}

But for the edit item it doesn't work correctly:

if (m_grid.EditItems.Count > 0)

{

m_grid.EditItems[0].FireCommandEvent("Update", String.Empty);

}

The GridSaveCommand event is called, but when I try to access my EditForm, it doesn't get found when updating (control will be null). When inserting, it works perfectly. What am I doing wrong when updating?

MyControl control = (MyControl )e.Item.FindControl("MyControl");

Thanks!
