I have a radcombobox with EnableAutomaticLoadOnDemand="true", when I select the combobox, all the data loads and I am able to select an item.  If I then click the same combobox, the value of the previous selection is present, therefore it will not load in any of the data untill i delete the text in the combobox.  Is there away around this?  I would like to the text to be cleared out so everytime a user clicks on the box it will load all the values in?

I have set up the radcombobox in the folloaing way
I bind the data in the following way,
Any help would be much appreciated

Hi,

I have been using Telerik Grid, on demand load data and i have implemented custom paging to my grid.
I have used VirtualItem count property to display max reocrds avilable with given query and default it will display 10 records perpage.
ex:-   24 items in 3 pages like this format i am displaying record count.(page size is 10)
24items i am getting using virtual item count.
But my problem is when when virtrual item count is greater than the pagesize, then the grid pagination bar(page index bar) is coming.
but when the virtualitem count is lessthan the pagesize(for example:- 3 recrods retruned from db,but page size is10) then pagination bar is disappearing.
so please provide me the better solution to resolve this issue.

Thanks in advance.

Hi all...

The problem is exactly that, when I filter the grid with the filters commands, how do I maintain those filters with EnableSEOPaging="true"?

When I use the pager, the filter is lost.

I'm using Telerik Q2 2008, although I don't think it makes any difference at all...

Thanks and best regards,
Sérgio Diniz

Hi,

Im just testing rad combobox. I need a behaviour like this: http://localhost:59468/radcontrols_aspnetajax/combobox/examples/functionality/filteringcombo/defaultcs.aspx

This is, a dropdownlist with autocomplete. I tried to isolate the example in a test APP, and the combobox is rendered, and partially works. Partially because the autocomplete behaviour does not work!

I did those steps:
- Added telerik dll to a test web project in the bin folder
- Referenced this dll
- Created the controls toolbox referencing this dll
- "drag and drop" the combobox, and setting those properties:

 

 

<telerik:RadComboBox DataSourceID="dsTestData" DataTextField="Name" ID="radCentral" runat="server"

 

 

 

AllowCustomText="true" ExpandAnimation-Type="None" CollapseAnimation-Type="None">

Any idea why the autocomplete does not work?

Thanks

 

Hi,

Our application Structure is mentioned below:
1) Master Page  header part contains the Rad Menu. On Menu Click Navigates to the respective content page.
2) All our content pages contains the RadGrid
3) We are using WebUserControl for the RadGrid EditForm.
Ref : http://test.aptisys.com/UOMSetup.aspx

I implemented the example with the Need data source, similar to the below mentioned telerik URL, (You can check our url  example in   http://test.aptisys.com/UOMSetup.aspx for reference).

http://demos.telerik.com/aspnet-ajax/grid/examples/dataediting/templateformupdate/defaultcs.aspx

Pls reply back to the below Query and send us some example samples:

 In the RadGrid disabled the EnableViewState="false", when i tried to read the value from the webusercontrol edit form from the code behind content page, while implementing the InsertCommand to insert uom_code, uom_name and uom_desc values returns the empty string from the web user control.
1) How to insert the value using the InsertCommand when the viewstate is set to false?
2) What is the syntex to retrieve value from the webusercontrol edit form to assign to the respective table column in the insert command method?
3) What is the workaround to overcome this problem? 
4) Could you please send us some example how to implement the need data source  to insert, update and delete command when enable view state is set to false?
5) If i implement the heirarchy grid using the Need Data Source with Web User Control as edit form and set the Enable view state = false, does the second level of the heirarchy grid supports Grouping, Sorting, Filtering? Could you please send us some example for the scenario implemented using the need data source with Enable View State is set to false?

 protected void RadGUOM_InsertCommand(object source, GridCommandEventArgs e)
    {
        GridEditableItem editedItem = e.Item as GridEditableItem;
        UserControl userControl = (UserControl)e.Item.FindControl(GridEditFormItem.EditFormUserControlID);
        //Create new row in the DataSource
        DataRow newRow = this.UOMCode.NewRow();
        //Insert new values
        Hashtable newValues = new Hashtable();
        newValues["uom_code"] = (userControl.FindControl("txtUcode") as TextBox).Text; (*Returns empty string)
        newValues["uom_name"] = (userControl.FindControl("txtUName") as TextBox).Text;(*Returns empty string)
        newValues["uom_desc"] = (userControl.FindControl("txtUdesc") as TextBox).Text;(*Returns empty string)

        //make sure that unique primary key value is generated for the inserted row
     //   newValues["EmployeeID"] = (int)this.Employees.Rows[this.Employees.Rows.Count - 1]["EmployeeID"] + 1;
        try
        {
            foreach (DictionaryEntry entry in newValues)
            {
                newRow[(string)entry.Key] = entry.Value;
            }
            this.UOMCode.Rows.Add(newRow);
            this.UOMCode.AcceptChanges();

        }
        catch (Exception ex)
        {
            Label lblError = new Label();
            lblError.Text = "Unable to insert Employees. Reason: " + ex.Message;
            lblError.ForeColor = System.Drawing.Color.Red;
            RadGUOM.Controls.Add(lblError);

            e.Canceled = true;
        }
        //RadGUOM.DataSource = null;
        //RadGUOM.Rebind();

    }

I'm trying to disallow the up and down arrow key press on the text area of the combo (to ensure users do not accidentally select a different item) and used the following example provided in:
http://www.telerik.com/help/aspnet-ajax/combo-prevent-typing-particular-characters.html.

i am using firebug to step through the problem, the event fires however, the keypress is not disallowed.
I reverted back to example and noticed the example does not work too.

Please advise or post a working example.

<script type="text/javascript">
 function pageLoad() {
        var combo = $find("<%= RadComboBox1.ClientID %>");
        var input = combo.get_inputDomElement();
        input.onkeydown = onKeyDownHandler;
    }

    function onKeyDownHandler(e) {
        if (!e)
            e = window.event;

        var code = e.keyCode;
        //do not allow any of these chars to be entered: !@#$%^&*()
        //if (e.shiftKey && code >= 48 && code  <= 57){
        if (code >= 39 && code <= 40) {
            e.returnValue = false;
            if (e.preventDefault) {
                e.preventDefault();
            }
        }
    }
</script>

Hi,
In my ListView control I have created a couple of buttons to edit/insert items. To go into edit mode or insert mode I have to click the button twice. The events are fired correctly however only with the second click resp the EditItemTemplate or the InsertItemTemplate is loaded.

What could be reason for this behavior?

Found a similar post: click control twice. This is similar to my issue. I do not use a datasource on the page however I set the datasource at page load.

Thanks,
Marc.
