Hi
I use a web service to populate the values in the RadCombo box. This RadCombobox has 3 columns. Which is defined in the header template (Please see the code). My problem is that I don't know how to organize the web service response to the corresponding matching columns defined in the header template. ItemTemplate sounds like useless here. It does nothing.  So all I want is 3 columns defined in the radCombobox and using the webservice to get data. Please help!!!

Please see below.

Web Service : CompanySelector.asmx

[WebMethod(CacheDuration = 60, EnableSession = true)]

public RadComboBoxItemData[] GetSystemCompanies()

{

 

string dataDomain= "<DataDomain><CountryCode>AU</CountryCode></DataDomain>";

int maxItemsToReturn = 25;

string prefixText = "";

DataTable dataTable = GetPrefixDataTableForTheDataDomain(dataDomain, prefixText, maxItemsToReturn);

List<RadComboBoxItemData> items = new List<RadComboBoxItemData>(dataTable.Rows.Count);

foreach (DataRow row in dataTable.Rows)

{

RadComboBoxItemData raditem = new RadComboBoxItemData();

 

raditem.Text = row["RegCode"].ToString() + "\t" + row["CompanyName"].ToString() + "\t" + row["CountryCode"].ToString();

raditem.Value = row["RegCode"].ToString() + "\t" + row["CompanyName"].ToString() + "\t" + row["CountryCode"].ToString();

items.Add(raditem);

}

return items.ToArray();

}

Hi Yana

Thanks for that. I got it working upto the way that it displays as columns usinig Web Services. Now the problem is it doesn't perform the autocompletion (Eg. Type text and drop down automatically populated with the rest of the text) as it used to. I went through the javascript files in the library and couldn't find why it is stopping. Can you please help?

Cheers.

Hi
Can someone please help!!! We are excited about using your controls but we need help what we need to achieve.

If I'm using web services for the auto complete drop down, can you please tell me how can get the auto complete behavior? Ultimately what I want to achieve is multicolumn autocomplete Telerik drop down using web service.
Any of the Telerik drop down demos in your web site doesn’t explained that.


For example please see below
.<WebServiceSettings Method="GetCompanyNames" Path="Products.asmx" />
How can I pass a parameter to the GetCompanyNames web method so I can only get the result start with latter ‘A’ ?

Please see my code below (the reference files are in the library which Yana provided)

Hi Raj,

I am sorry I didn't reply earlier.

You get all the data for combobox in GetCompanyNames method with this line:

DataTable data = GetPrefixDataTableForTheDataDomain(appUserDataDomain, prefixText,
 maxItemsToReturn); 

you should use  "context.Text" in your query to the database in order to select only those items which correspond to some conditions like in the example:

 string sql = "SELECT * from Customers WHERE CompanyName LIKE '"   
+ context.Text + "%'"

please modify your query and let us know how it goes.

All the best,
Yana

Thanks heaps for your advice. it was very useful. Now i'm in the final stage of this, Probably the last question for you. When I click on the vertical scroll bar, the items in the drop down get duplicated. Which means as soon as i click on the vertical scroll bar the items get doubled (duplicated) in the drop down list. I went thru the js files but I can't locate where it is happening. Can you please help?

Hi Yana

The issue is when I click on the scroll bar it triggers the web service, and data binding again. It is possible to stop this? I mean I still want to scroll it, but want to stop triggering the web service. The other thing I can think of is the items returning from the web service is adding to the existing items list without clearing the previous list. Any suggestions greatly appreciate?


Cheers,

Raj

Hello Raj,

EnableVirtualScrolling property of RadComboBox allows you to dynamically add items when scrolling, so you have to load the items in portions in your GetCompanyNames web method. Please check our example "populated from WebService combobox" where it is shown exactly how to do that.

Thanks Yana.

All good. Thanks alot. One last question. Please see the code below. The order of the columns are Code, Company Name and Country, The prepopulating for the text is working for the code, but not for the name. So how to get the pre populating (autocompletion) for the name instead of the code without changing the columns order. So I want to see the order as Code, Company Name, country (as it is now), and prepopulating the company name instead of the code (currently the code prepopulate in the text box)

Thanks

Regards,

Raj

Sorry my previouse question is not the last question I have :) Once I integrated my developed solution to our main project, I came across with few issues. They listed below.

1. Just to recap I still need help to figure it out a solution to my previouse question regarding the column order?

2. prototype-1.6.0.2.js is massive and is there a cutdown version of this library to support the autocomplete functionality? Do you have a JQuery support for this? Because the control is going to be added to every page in our main project so this js file will be referece everywhere?

Cheers,

Raj

Hello Raj,

You define which items to be loaded in your query to the database, you can use the entered by the user text to search the code or what field you want. The column order is defined in your cb_onDataBound function so it's not related to the search field.

Unfortunately we don't have a cutdown version of prototype-1.6.0.2.js file or a jquery support as this example actually is submitted by a client.

Kind regards,

Hi Yana
Thanks so much for the assitance and we are happy with the performance and the functionality of the control. I have a one question though. I'm not sure whether this is a bug within the control itself or not. This problems happen in any RadComboBox control which has the auto complete bahaviour.

Step to reproduce"

1. Type a name in the text box. This would trigger a POST request to the web service.
2. Before the response received key in a space character. Try this few times until you don't get a reponse.
3. Now the control make infinit requests to the web server, and never stop until the control crash.(Firebug/Fiddler would show this)

So every time the loop occure it appends %20 to the request to the web server. For example context.Text = NAME%20%20%20%20%20%20
 
Do you aware of this issue?. Is their a fix for this? This occured in any Combo box auto completion control
POST Request copied from Fiddler :

{"context":{"NumberOfItems":0,"Text":"IBM%252525252520"}}
{"context":{"NumberOfItems":0,"Text":"IBM%25252525252525252525252525252525252525252520"}}
{"context":{"NumberOfItems":0,"Text":"IBM%252525252525252525252525252525252525252525252520"}}


Thanks again Yana!! I deas greatly appreciated.

Cheers,

Raj

Hi Yana

We have reproduced this particular problem in the sample application you game me. It happens when there is a slow response from the sql (due to slow network connection to sql) and we send another POST request (before the previous one returned) with a space character. This is really hard to reproduce when the performance are very good. But when performance of the network connection is bad it is easy to reproduce. You need to type a name with ending space character (Eg. "IBM " ) and before the response comes remove the space character and repeatedly do this few times. 

{"context":{"NumberOfItems":0,"Text":"wb%252525252525252525252525252520"}}
{"context":{"NumberOfItems":0,"Text":"wb%252525252525252525252525252520"}}
{"context":{"NumberOfItems":0,"Text":"wb%252525252525252525252520"}}


Can we please have a fix for this? We have some server which is in US and reponse time are not that great.

Hello Raj,

Could you please download our latest SP2 release (version 2008.3.1314) and try with it? We have fixed some issues concerning auto-complete functionality of RadComboBox recently.

Best wishes,

Hi Yana

Thanks a lot for your assistance. We greatly apreciate it. We decided to download the SP2 release but not for the current release. We will download it for the next release and see how we go. The control looks great. Once again THANKS A LOT!!!!.

I got the same error for the rad combobox  where text value returened is OLD%252525252525252520ADOPT%252525252525252520SVCS%252525252525252520RGN%252525252525252520III%252525252525252520(Orangeburg).KeyNotFoundException was unhandled by user code.

"The given key was not present in the dictonary"

string relatedValue = e.Context["RelatedValue"] != null ? e.Context["RelatedValue"].ToString() : ""; at this line.

I am working on the  protected void RadComboBox1_ItemsRequested(object sender, RadComboBoxItemsRequestedEventArgs e)
        {

RadComboBox comboBox = sender as RadComboBox;

            //GridEditableItem dataItem = comboBox.r as GridEditableItem;
            
            string columnName = e.Context["ColumnName"].ToString();
                       
                string relatedValue = e.Context["RelatedValue"] != null ? e.Context["RelatedValue"].ToString() : "";

}

Since this thread is quite old (started 2009) and several different issues are discussed, I would like to ask you to elaborate a bit more on the experienced issue at your end and the intended functionality.
