Question

美好的一天，

我有一个带有RadTextbox的GridTemplateColumn。文本框值由javascript更改。但是当我单击文本框时，它会更改回原始值。

请帮忙

的javascript

<title>Untitled Page</title>

<script type="text/javascript">
    function changeCountry() {            

        var grid = $find('<%=RadGrid1.ClientID %>');
        var MasterTable = grid.get_masterTableView();            
        var dataItems = MasterTable.get_dataItems();

        var cellCountry = dataItems[0].get_cell("CountryCol");
        var txtCountry = $telerik.$(cellCountry).find('input')[0];
        txtCountry.value = "New Country";        
    }
</script>

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
{
    if (e.Item is GridHeaderItem)
    {
    }
    if (e.Item is GridDataItem)
    {
        GridDataItem dataItem = (GridDataItem)e.Item;

        RadTextBox txtCountry = ((RadTextBox)dataItem.FindControl("txtCountry"));
        txtCountry.Text = dataItem["CR_Country"].Text;

    }

}

您需要使用Telerik客户端脚本 set_value 功能，而不是纯粹的javascript / HTML，即

function changeCountry() {            

    var grid = $find('<%=RadGrid1.ClientID %>');
    var MasterTable = grid.get_masterTableView();            
    var dataItems = MasterTable.get_dataItems();

    dataItems[0].findControl("txtCountry").set_value("New Country");
}

RadGrid中的文本框由客户端更改
