Dynamically Created TextBox Doesn't Hold the .Text Property
I have a form I've created to map data from Excel into our SQL Server-based system.  The basic idea is that a user picks the Excel file to upload, then "maps" the data by selecting the database field then the corresponding Excel column.  Once the user has "mapped" a file, they can save that "mapping" for future use.

The data on the mapping screen consists of two columns - one an asp:Panel full of dynamically created RadTextBoxes representing the fields in the database (created from the DBSchema) and the other being a GridView of the "column headers" and the first row of data from the Excel file.  From there it's all point and click to map the data - Click on a database field then click on the Excel column. Javascript is used to populate the RadTextBox with the column information and to "remove" the row from the Excel GridView (so a column can only be mapped once).

When the user "saves" a mapping, the dynamically created RadTextBoxes are walked and rows are created in SQL Server using the name of the RadTextBox and part of the Text property.

All this works fine.

The problem I have is when the user tries to "load a mapping" that has previously been saved.  Using the routine that creates the list of RadTextBoxes, I populate the Text property with data from the DB (and set some CSS wrapping the "row").  This is where my problem lies.  I set the Text property, but the value is empty when the page is rendered.  I can set breakpoints in the code and "see" that the property is set to the proper value, but it still displays empty.

Futhermore - I can set the EmptyMessage property to the same value I'm attempting to place in the Text property and have that display. So something I'm doing is stomping on the Text property, but I just don't see it.  I've stepped line-by-line through the code and the values "hold" but just don't display - unless I take a long time stepping through the code, then it works .....

I'm not quite sure what's going on with this since I can get this to work by itself, just not in conjunction with the rest of the page.

I'm using RadControls for ASPNET AJAX Q1 2009

Here's the code for the function that creates the RadTextBoxes.  On a page by itself it works fine and with ASP:TextBox controls it works fine.  I know this probably isn't enough to go on, but there does seem to be a case when a dynamically created RadTextBox doesn't "hold" the .Text property :)

protected void FillFieldList(MappingType mtType, Guid? nguidFieldMappingID)  
{  
    DataTable dtLayout = Property.GetDBSchema();  
    RadTextBox rtxtNewTextBox;  
    FieldMappingItem fmiMappings = new FieldMappingItem();

    {  
        fmiMappings = new FieldMappingItem(nguidFieldMappingID);  
    }  
 
    foreach (DataRow drData in dtLayout.Rows)  
    {  
        if ((drData["DataTypeName"].ToString() != "uniqueidentifier") && (drData["ColumnName"].ToString() != "Created"))  
        {  
            strMappedName = string.Empty;  
            sbControl = new StringBuilder();  
            sbControl.Append("<div id=\"div");
            sbControl.Append(drData["ColumnName"].ToString());
            sbControl.Append("\" onclick=\"SelectRow('div");
            sbControl.Append(drData["ColumnName"].ToString());
            sbControl.Append("');\"");  
 
            foreach (FieldMappingDetailItem fmdiDetails in fmiMappings.Details)  
            {

                {  
                    bolMappedFound = true;

                    strMappedName = fmdiDetails.MappedName;  
                    break;  
                }  
            }  
 
            if (bolMappedFound)  
            {  
                bolMappedFound = false;  
            }  
            else 
            {  
                sbControl.Append(">");  
            }  
 
            this.pnlFields.Controls.Add(new LiteralControl(sbControl.ToString()));  
 
            rtxtNewTextBox = new RadTextBox();  
            rtxtNewTextBox.ID = "rtxt" + drData["ColumnName"].ToString();  
            rtxtNewTextBox.CssClass = "FormFieldMapping";  
            rtxtNewTextBox.Label = drData["ColumnName"].ToString();  
            rtxtNewTextBox.LabelCssClass = "FormLabel";  
            rtxtNewTextBox.EmptyMessage = strMappedName;  
            rtxtNewTextBox.Text = strMappedName;  
            this.pnlFields.Controls.Add(rtxtNewTextBox);  
              
            sbControl = new StringBuilder();  
            sbControl.Append("<input type=\"hidden\" id=\"hdn");
            sbControl.Append(drData["ColumnName"].ToString());
            sbControl.Append("\" value=\"");  
            sbControl.Append(rtxtNewTextBox.ClientID);  
            sbControl.Append("\" />");  
            this.pnlFields.Controls.Add(new LiteralControl(sbControl.ToString()));

In RadGrid Nest a RadChart
Hi Telerik:

This is a question perplex me.
In RadGrid,Nest a RadChart,Of course ,that data bind to radGrid.
There are two kind of think. 
        First : Through data of  radGrid takes datasource to radChart. This think source think of silverlight.
        Second: Through keyColumn of  radGrid ,Execute StoredProcedure with parameter to bind radChart. Why needing execute StoredProcedure ,Because I must process some things. The SqlDataSource seem to can't to execute  StoredProcedure with parameter.

I try to two ways,but fail.I  distressed.

[Solved] Find blank Cell value in Radgrid
I am switching over a gridview to a radgrid and ran into a hiccup, Gridview when a cell is blank actually puts in a &nbsp; so you have to check for this , apparently Radgrid works differently.  I am trying to find out if a cell is blank or not, if its blank I want to hide a button on the radgrid.
Protected Sub myRadGrid_ItemDataBound(sender As Object, e As Telerik.Web.UI.GridItemEventArgs) Handles myRadGrid.ItemDataBound
       If (TypeOf e.Item Is GridDataItem) Then
           Dim button As LinkButton = e.Item.FindControl("lnkPickUp")
           Dim text As String = e.Item.Cells(7).Text
           If text = Nothing Then
               button.Enabled = False
               button.Visible = False
           End If
       End If
   End Sub

Anybody please ? RadMenu control error
Hi..
Anyone please...

We are using telerik rad menu control to list out rad menu items in silverlight project . Sometimes it's working well, but sometimes it's shows control error message.

In my project we have Rad treeview , if we select a Rad treeview item, it will open and the title of the treeview item should add in RadMenu items. If I mouseover on RadMenu it will show the menu items what are all added. And close the treeview item which is opened.  Then, again we are open the same treeview item.

Now, the title of treeview item added successfully in RadMenu items in code side using break points. But In design, If I mouseover on RadMenu, it's not show the RadMenu items what are all added. Instead It shows the control related error message box.

code for Add Menu item in RadMenu : Sample1.xaml.cs
**********************************************************************************************************************************************************************

            child.Click += (s, e) => MenuItemShowWindowClick(s, e);

Adding Items to Telerik RadContextMenu showing transparent background

Following is the javascript code where I am adding few items in existing rad context menu i.e. RadMenu1. There are few items already in it and I am adding few more items dynamically in javascript 

function ContextMenuOpen(sender, args) 
{
    var menu = $find("m_c_RadMenu1");
    if (IsMobileBrowser() == false) 
    {
        var evt = args.get_domEvent();
    }
    menu.trackChanges();
    var items = menu._getAllItems()
    menu.get_items().clear();

    //menu.commitChanges();
    AddItem("Visit & View Details", "a");

    if (selectedRow.findElement("lblTask") != null) {
        var tasklist = selectedRow.findElement("lblTask").defaultValue;
        var taskArray = tasklist.split(',');

        for (i = 0; i < taskArray.length; i++) {
            if (typeof (taskArray[i].split('~')[1]) == 'undefined') break;
            AddItem("Perform " + taskArray[i].split('~')[1], taskArray[i].split('~')[0]);
        }
        //rb.AddItem(selectedRow.findElement("lblTask").innerText,4)
    }
    AddItem("Log an Incident", "b");
    if (rb.isLocationSelected == false) {

    AddItem("Log a Discrepancy", "c");
}


function AddItem(text, value) {
    var menu = rb.GetMenu();
    var item = rb.GetContextMenuItem(text);
    if (item != null) return false;
    var menuItem = new Telerik.Web.UI.RadMenuItem();
    menuItem.set_text(text);
    menuItem.set_value(value)
    menu.trackChanges();
    menu.get_items().add(menuItem);
    menu.commitChanges();
    return true;
}

Everything goes well , but the newly added context menu shows transparent background on rightside , I found it is filling the background only at the area where text is present , on empty area at rightside it is transparent (see attached image )

see the transparent background, right side of the items

do anybody know how to remove this transparent background?

Control in item template is not recognizing
Hai,

I have a hiddenfield in the item template of a Radcombo. I have to take the value of hiddenfield in the SelectedIndexChanged event of radcombo. I used the following method as per your website refernece for radcombo. This code was working fine. But one day it started not working, showing null reference exception in finding the hiddenfield. I didn't change anything.

protected

 

void rcbTruck_SelectedIndexChanged(object sender, Telerik.Web.UI.RadComboBoxSelectedIndexChangedEventArgs e)

 


{

RadComboBox

 

combo = (RadComboBox)sender;

 

 

RadComboBoxItem item = (RadComboBoxItem)combo.SelectedItem;

 


hidDailyOrderDetailId2.Value = ((

HiddenField)item.FindControl("hidDailyOrderDetailId1")).Value;

 


}

aspx

<

 

asp:HiddenField ID="hidDailyOrderDetailId2" runat="server" />

 



<

 

telerik:RadComboBox ID="rcbTruck" runat="server" DropDownWidth="250px" Width="250px"

 

 

ShowToggleImage="true" Height="140px" AllowCustomText="True" MarkFirstMatch="False"

 

 

HighlightTemplatedItems="True" TabIndex="2" EmptyMessage="--Select--" AutoPostBack="true"

 

 

EnableLoadOnDemand="True" Skin="Web20" ToolTip="Please Select truck" MaxHeight="250px"

 

 

OnItemsRequested="rcbTruck_ItemsRequested" OnSelectedIndexChanged="rcbTruck_SelectedIndexChanged">

 

 

<ItemTemplate>

 

 

<input id="hidScheduledStartTime" type="hidden" runat="server" value='<%#DataBinder.Eval(Container.DataItem,"ScheduledTime") %>' />

 

 

<asp:Label ID="lblVehicleName" runat="server" Text='<%#DataBinder.Eval(Container.DataItem,"VehicleName") %>'></asp:Label>

 

 

<asp:HiddenField ID="hidDailyOrderDetailId1" runat="server" Value='<%#DataBinder.Eval(Container.DataItem,"Daily_Order_Detail_Id") %>' />

 

 

</ItemTemplate>

 

 

</telerik:RadComboBox>
