Getting DataKey from selected item

[Ahrensberg]

Hi all,

My MasterTable is defined by:

<MasterTableView DataKeyNames="id">
    <Columns>
        <telerik:GridBoundColumn HeaderText="Street" DataField="Address.Street" />
        <telerik:GridBoundColumn HeaderText="HouseNumber" DataField="Address.HouseNumber" />
        <telerik:GridBoundColumn HeaderText="ZipCode" DataField="Address.ZipCode.Code" />
        <telerik:GridBoundColumn HeaderText="City" DataField="Address.ZipCode.City" />
    </Columns>
</MasterTableView>

And I want to get the id of the selected item client side. I thought that this would do the trick:

// Javascript
var selectedItem = $find("MyGridClientID").get_masterTableView().get_selectedItems()[0];
var selectedItemID = selectedItem.getDataKeyValue("id");

But this 'selectedItemID' is following null. What do I do wrong? :o/

Hello Ahrensberg,

Try setting the ClientDataKeyNames property of the MasterTableView to the datafield of the column(id in your case).

Check out the following document which shows an example:

Thanks

I tried to do as in the example:

var firstDataItem = $find("MyGridClientID").get_masterTableView().get_dataItems()[0];
var keyValue = firstDataItem.getDataKeyValue("id");

But keyValue is still null (firstDataItem is not)... :-S

DO'H! Should of course set 'ClientDataKeyNames' instead of 'DataKeyNames' - as you wrote! ;o)

Thank you! :o)

What's the correct link to the Extracting key values client-side article?
