Hi,
Thank you for your reply.
I have created a DropDownListTemplate class and implemented interface to bind data to the DropDownList, and now it shows up on gridview which is a good start, but I am wondering how to do selectedValue of dropdown list databind in EO.Web.GridView, because I can't cast EO.Web.Internal.b9 to Web.UI.GridViewRow,
Could you please give me any solutions on this?
Thanks
William

Hi, You don't need to cast anything. You will need to put in some JavaScript code to get or set a value from and to your drop down list. The Grid does not create a editor template (your DropDownList) for every cell. It creates a single one and reuse them for all cells. You can take a look of this topic to see more details about custom column: http://doc.essentialobjects.com/library/1/grid/custom_column.aspxThe only difference between your code and the sample code in the documentation is your drop down is created with server code, thus it will have a different ClientID. Everything else is the same. Thanks!

Hi, There are various way to do it but it always come down to submitting the page. The basic rules are: 1. You need to submit the page one way or another. Just like a TextBox will not send the changes to the server side unless the page is submitted, the Grid will not send any changes to the server unless the page is submitted; 2. If you need to submit the page inside one of the Grid's client side event handler, you usually need to delay your code with setTimeout. For example, if you submit the page inside a GridColumn's ClientSideEndEdit handler, you can delay executing your code with setTimeout this way:
Code: JavaScript
setTimeout(function()
{
....your code to submit the page....
}, 10);
This is necessary so that the Grid can finish its "normal" flow first before you posting back the changes. There are various ways to submit a page, none is really particularly related to the Grid. You can also use AJAX calls if needed. In addition, we have a ScriptEvent control that you may find easier to use. All those are available options. But in the end they all need to do the same thing a button does --- to submit the page. And as far as the Grid's concern, it handles everything the same way as if a button was used. Thanks!
