RadTabStrip / RadMultiPage state lost when inside nested control in SharePoint web part

Embedding a RadMultiPage / RadTabStrip directly into a SharePoint web part works fine, but for code organization I would like to nest them into a separate control. Once I do this, the control re-creation doesn't work (at least, not the ways I have tried it :)). Specifically, when the RadMultiPage / RadTabStrip are part of the WebPartWithTelerik class (which inherits from System.Web.UI.WebControls.WebParts.WebPart), the RadGrid controls on each page allow editing correctly; however, when they are moved down into the WebPartPanel class, clicking Edit on the RadGrid on either page causes the entire page to re-load, and the controls are not in edit mode as their state has been lost.

Scenario:
* RadTabStrip / RadMultiPage combo with two RadPageView objects.
* Each RadPageView contains a single RadGrid which retrieves data via LinqToSql data sources.
* MOSS web site using VSEWSS 1.3 to build the web part in VS 2008.

I've tried a few iterations of this (attemping to serialize the container object, etc.) with no success. Here's hoping there's a simple fix out there.

Thanks,

William Cook

[Solved] DataSet into RadGrid

Dear friends,

Take a look at the following code:

                    webappteste.WebReferenceX.Service1 sd = new webappteste.WebReferenceX.Service1();         
            DataSet ds = new DataSet();         
            ds = sd.getClientes(); //Get full list of customers from a web service        
            DataTable dt = new DataTable("clientes");         
            dt = ds.Tables[0];         
            RadGrid1.DataSource = dt;         
            int asd = dt.Columns.Count; //Returns 58 columns - CORRECT        
            string tableName = ds.Tables[0].Columns[0].ToString(); //Returns the column name "CLIENTE" - CORRECT        
            int b = ds.Tables[0].Columns.Count; //Returns 58 columns - CORRECT        
            int a = RadGrid1.Columns.Count; //Return 0 columns - WRONG - Why not 58 columns???        

Can you tell me why this is happening?

Is there any other way to load a DataSet into a RadGrid?

Thanks in advance!!

WebService:

[WebMethod]
                    public DataSet getClientes()         
            {         
              SqlDataAdapter dataAdapter = new SqlDataAdapter("SELECT * FROM CLIENTES ORDER BY    NOME",connections.retConn())         
              DataSet dataSet = new DataSet();         
              dataAdapter.Fill(dataSet);         
              return dataSet         
            }

ComboBox _ItemsRequested Problem

Hi All,

Here i had used RadComboBox with _itemsrequested property and also total count of the items(i.e Items 1-5 out off 20) in the combobox at the bottom, Their is an issue regarding that (i.e on page load when i click on the combobox for the first time i am unable to get the total count of the combobox items but when i click on the area where i get that message then i will be getting the items message (i.e Items 1-5 out off 20) this message is been placed in the _itemsRequested so i am able to get the items message at the bottom of the combobox so how do i get the items count message on page load when i click on the combobox for first time.

Here is the code

protected void cmbPlatformName_ItemsRequested(object o, RadComboBoxItemsRequestedEventArgs e){DataTable data = objTaskmanLib.GetData(e.Text); //GetData(e.Text);

//objTaskmanLib is the library file from where i get the count.

RadComboBoxItem item = new RadComboBoxItem();int itemOffset = e.NumberOfItems;int endOffset = Math.Min(itemOffset + ItemsPerRequest, data.Rows.Count);e.EndOfItems = endOffset == data.Rows.Count;for (int i = itemOffset; i < endOffset; i++){cmbPlatformName.Items.Add(new RadComboBoxItem(data.Rows[i]["Platform_Name"].ToString(), data.Rows[i]["Platform_Name"].ToString()));}e.Message = GetStatusMessage(endOffset, data.Rows.Count);}private string GetStatusMessage(int endOffset, int total){if (total <= 0)return "No matches";return String.Format("Items 1-{0} out of {1}", endOffset, total);}

Here i had used this GetStatusMessage function only in the _itemsRequested event so i am able to get the items message(i.e Items 1-5 out off 20) when i click on the area where items message is been displayed. so can any one help me how to use this function on page load also.

Thanks in advance.

Paging not working

I am using the following: VS2008, Windows XP, IE7, the latest Telerik product and C#.

I have used the Configuration Tool to set my data instead of writing backend code to do so.
My Datasource is as follows:

<asp:EntityDataSource ID="EntityDataSource1" runat="server"

ConnectionString="name=AllDataModels" DefaultContainerName="AllDataModels"

EntitySetName="Project" Select="it.[Name], it.[Identifier], it.[ID]">

</asp:EntityDataSource>

I have then selected from the RadGrid Tasks from the arrow in design view --> General Features and checked "Enable Paging".

I am getting a error on the page when paging is enabled, but when paging is not enabled... the data is generated just fine and I can see all. When I enable paging ... I get the error again.

Here is my aspx code:

<

telerik:RadGrid ID="RadGrid1" runat="server"

style="z-index: 1; left: 9px; top: 122px; position: absolute;"

AllowSorting="True" DataSourceID="EntityDataSource1" GridLines="None"

AllowPaging="True">

<

MasterTableView AutoGenerateColumns="False" DataSourceID="EntityDataSource1">

</RowIndicatorColumn>

</ExpandCollapseColumn>

<telerik:GridBoundColumn DataField="Name" HeaderText="Name" ReadOnly="True"

SortExpression="Name" UniqueName="Name">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="Identifier" HeaderText="Identifier"

ReadOnly="True" SortExpression="Identifier" UniqueName="Identifier">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="ID" DataType="System.Int32" HeaderText="ID"

ReadOnly="True" SortExpression="ID" UniqueName="ID">

</telerik:GridBoundColumn>

</Columns>

</MasterTableView>

</telerik:RadGrid>

Thanks for any help you can give. :)

[Solved] Help with Combo client code

Argh...I apologize for bugging everyone at this time of the year, but I am having issues trying to retrieve the selected values from a combo box inside client javascript and am working on a demanding schedule.

I have a combo box (for example) populated as:

Item 1: Text=Sell; Value=1.
Item 2: Text=Rent; Value=2.
Item 3: Text=Trade; Value=3.

When the user selects an item from the combo (and enters text in a couple of textboxes) then clicks on an item on the screen, I need to open a new window and pass the value selected in the combo box. I can't do this inside the server code, because a postback would end up basically performing a redirect and I need to keep the original window on the screen.

I cannot capture the combo box selected value when the user selects it, because they may just use the default value thus not triggering any events on the combo box before clicking on the screen item to continue.

I should add that I am using the combo box on a page that utilizes a master page, and that the combo box is defined inside a RadDock.

In my client javascript, I have tried several methods of doing this, but all I can seem to retrieve is the text value displayed in the combo box. For examples:

Example 1. The following code retrieves the actual visible text value from the combo (i.e. - trade, sell, rent)

a1 = document.getElementById("<%= ListTranType.ClientID %>").value;
alert(a1);

Example 2. In the following, b1 displays [object object] and b2 displays undefined

var b1 = $find("<%= ListTranType.ClientID %>");
alert(b1);
var b2 = b1.value;
alert(b2);

Example 3. The following code works exactly like #1 above. Only the visible text from the combo is displayed (sell, rent, trade).

var b1 = $find("<%= ListTranType.ClientID %>").value;
alert(b1);

The combo box is defined as shown below.

<

telerik:RadComboBox ID="ListTranType" OnClientSelectedIndexChanged="gettrantype" EnableEmbeddedSkins="true" Skin="Black" runat="server" Width="200px" ></telerik:RadComboBox>

I do have a script for capturing the value when the user selects one and it works fine as it is, but as said earlier sometimes the user will use the default value or not select one from the combo before clicking to proceed. Both of these actions are valid within the application. The code used to capture the value during the event is:

var trantype;

function gettrantype(combo, eventArqs) {

var item = eventArqs.get_item();

trantypeval = item.get_value();

}

SUMMARY QUESTION: What I need to retrieve from the combo box is the data loaded as the "value". In the examples above, this would be either the 1, 2, or 3 -- not sell, rent, or trade. How do I get the true selected value from the combo?

Thanks very much in advance!
