Access checked items in C#

[Dona]

Hi

There is a radcombobox with checkboxes enabled and how can I access all the checked items in C# code?

Thanks all
Dona.

Hello,

You can use the RadCombobox's "CheckedItems" propertie to get all items which are checked.

Ex:

var collection = comboBox.CheckedItems;

Please refer the link which will give you complete details.

Thanks,

Not working. I am getting Count=3 on debugging. I want to access all those values of items.

Hi Dona,

Please try the following C# code.

C#:

foreach (RadComboBoxItem checkeditem in RadComboBox1.CheckedItems)
{
    string _value = checkeditem.Value; //looping through each checked item and accessing its value.
}

Thanks,
Princy.

to get the checked combobox values in telerik (using javascript)

var checkeditems;

var combo = $find("<%= telerikcomboboxname.ClientID%>")

 var items = combo.get_checkedItems();

  for (i = 0; i < items.length; i++) {

                        if (i == 0) {
                            radvalue = Number(parseInt(items[i]._properties._data.value));
                           checkeditems=checkeditems+radvalue ;
                        }
                        else {
                            radvalue = Number(parseInt(items[i]._properties._data.value));
                            checkeditems= checkeditems+ "," + radvalue;
                        }

               }
                    alert(Expenseitems);

 

this will work 

thanks all

Hi Rajeeve,

Thank you for the suggested solution.

Note that this topic is on accessing checked items in the code-behind (C# / VB), while your suggestion is a client-side solution.

Note also that you won't need to use private properties (_properties and _data) of the RadComboBoxItem object to access the values of the item. You could freely use instead the get_value() method from the exposed client-side API of the object.

Moreover, if you do not initially set an empty string as a value of the checkeditems variable, it will produce the final result to have an "undefined" as prefix. In your suggestion, you also alert the wrong variable (Expenseitems), while the values are held in the checkeditems.

Modified working version of your sample code would be:

var checkeditems = '';
var radvalue;
var combo = $find("<%= RadComboBox1.ClientID%>")
var items = combo.get_checkedItems();
for (i = 0; i < items.length; i++) {
    radvalue = items[i].get_value();
    if (i == 0) {
        checkeditems = checkeditems + radvalue;
    }
    else {
        checkeditems = checkeditems + "," + radvalue;
    }
}
alert(checkeditems);

Hi Veselin Tsvetanov,
      Here I am using a RadCheckedDropDownList for multi select value. Where I want all checked values of   RadCheckedDropDownList  to the datatable.
Please Refer how could I add to the datatable the checked values  from the checked list of RadCheckedDropDownList.
I need Like this : ' if(Checkeddrpdwnlist1.checked==true) ' then the value to datatable.
Thanks 
Jamsheer
