I have a Page which a FormPanel(there's a ComboBox in it) and a TreePanel(has a default root node) in it and open ViewState.
I set a value to ComboBox in GET.
When i GET the page the TreePanel's Store send a POST request(store read) before FormPane rendered in client,in this POST request the fromdata has no info about FormPane.
in the POST request recover the ComboBox.Value from ViewState,but in ComboBoxBase.LoadPostData() Ext.Net get value from formdata and cover ComboBox.Value without precondition
it's ComboBoxBase.LoadPostData() code
protected override bool LoadPostData(string postDataKey, NameValueCollection postCollection)
{
this.HasLoadPostData = true;
string text = postCollection[this.UniqueName];
string state = postCollection[this.ValueHiddenName.IsNotEmpty() ? this.ValueHiddenName : ("_" + this.UniqueName + "_state")];
this.SuspendScripting();
this.RawValue = text;
this.Value = text;
this.ResumeScripting();
if (state == null && text == null)
{
return false;
}
if (!this.EmptyText.Equals(text) && text.IsNotEmpty())
{
List<ListItem> items = null;
if (this.SimpleSubmit)
{
var array = state.Split(new char[] { ',' });
items = new List<ListItem>(array.Length);
foreach (var item in array)
{
items.Add(new ListItem(item));
}
}
else if(state.IsNotEmpty())
{
items = ComboBoxBase.ParseSelectedItems(state);
}
bool fireEvent = false;
if (items == null)
{
items = new List<ListItem>
{
new ListItem(text)
};
/*fireEvent = this.SelectedItems.Count > 0;
this.SelectedItems.Clear();
return fireEvent;
*/
}
foreach (var item in items)
{
if (!this.SelectedItems.Contains(item))
{
fireEvent = true;
break;
}
}
this.SelectedItems.Clear();
this.SelectedItems.AddRange(items);
return fireEvent;
}
else
{
if (this.EmptyText.Equals(text) && this.SelectedItems.Count > 0)
{
this.SelectedItems.Clear();
return true;
}
}
return false;
}
Look at Line 5 to 11,why not change like this
string text = postCollection[this.UniqueName];
string state = postCollection[this.ValueHiddenName.IsNotEmpty() ? this.ValueHiddenName : ("_" + this.UniqueName + "_state")];
this.SuspendScripting();
this.RawValue = text;
this.ResumeScripting();
if (state == null && text == null)
{
return false;
}
this.SuspendScripting();
this.Value = text;
this.ResumeScripting();

We committed the change to the SVN trunk. It will go to the next release (v2.3).
The change is similar to your one, but we decided not to change RawValue as well. Thank you for the report and suggested fix.

I am using PagedDataSource To Paginate Repeater and it works fine but is there a way to highlight selected page number or make it bold. I tried css, itemcommand,and click event but no luck.
Thanks in advance
Repeater:
<asp:Repeater ID="repeaterPager" runat="server" OnItemCommand="repeaterPager_ItemCommand">
<ItemTemplate>
<asp:LinkButton CssClass="sayfaNo" ID="btnPage" CommandName="Page" CommandArgument="<%#Container.DataItem %>" runat="server">
<%# Container.DataItem %></asp:LinkButton>
</ItemTemplate>
</asp:Repeater>

Logic:
Use ItemDataBound event and compare currentpage with current value of btnPage. You may use FindControl to get the current btnPage value.
Hope that helps!

I would like to use multiple radio groups within a single rootelelement with monotouch dialog. Each radiogroup would have its own section. I can't find a way to make this work because a single radiogroup can only be assigned to the rootelement

I try to store all data from an object called BinNews, to a vector called binN. But when I do debugging, I found that BinN has null value, because "binN.addElement(bin)" doesn't work.
Please advise.
First, you don't actually call setBinN until after the while(i < 10) loop completes. So when you say binN.addElement(bin) then binN will be null.
However your setBinN(binN) call doesn't make sense because you're passing in binN and then setting it to itself which isn't going to do anything.
What you can do is have binN = new Vector(); at the top of the constructor and then it won't be null later on. I don't think the setBinN call will be necessary later on if you're adding the BinNews objects straight to binN.
This is my dictionary format:
word Frequency
Gone 60
Goes 10
Go 30
So far the system returns words eg starting with 'g' as go30, goes10, gone60 as a list.
(alphabetically). I want to increase the accuracy of the system so that the search result is based on frequency. Words with high frequencies appear first. kindly help.

I am getting the error
Missing operand before '=' operator.
when I try and export and the code is running fine in the grid.
Here is the code for the web part. The error only occurs on the rebind. It works fine in the grid itself. Is there any way to narrow down the exact thing it is erroring on?
I am willing to pay for a support / solution to this problem, I just need it to work.

As a follow-up, it appears the problem was that there were NULL values in John's original data. These nulls were causing problems during the data export. Fixing the null values also fixed the Excel export. Original solution on Telerik.com forums:
