我通过以下代码使kendo网格中的字段可编辑：
Html.Kendo().Grid(Model.lstResend)
.Name("ResendFlowGride")
.Columns(
column =>
{
column.Bound(e => e.FLOW_ID).Title("Id").Hidden(true);
column.Bound(e => e.GROUP_ID).Title("Group Id").Hidden(true);
column.Bound(e => e.GROUP_NAME).Title("Group Name");
column.Bound(e => e.ITEM_ID).Title("Item Id").Hidden(true);
column.Bound(e => e.ITEM_NAME).Title("Item Name");
column.Bound(e => e.ITEM_VALUE).Title("Item Value");
// column.Bound(e => e.ITEM_VALUE).Ed
}
)
.Editable(editable => editable.Mode(GridEditMode.InCell))
.DataSource(datasource => datasource.Ajax()
.Model(model =>
{
model.Id(p => p.ITEM_ID);
model.Field(p => p.ITEM_ID).Editable(false);
model.Field(p => p.GROUP_ID).Editable(false);
model.Field(p => p.GROUP_NAME).Editable(false);
model.Field(p => p.ITEM_NAME).Editable(false);
model.Field(p => p.ITEM_VALUE).Editable(true);
})
.Update(update => update.Action("Update", "Registration"))
)
我有以下控制器：
public ActionResult Update([DataSourceRequest]DataSourceRequest request, ResendFlow txns)
{
try
{
if (txns != null && ModelState.IsValid)
{
var regDetailsToUpdate = _repository.Context.REG_REGISTRATION_MST_T.Where(x => x.REGISTRATION_ID == txns.Reg_Id).FirstOrDefault();
_repository.Update(regDetailsToUpdate, regDetailsToUpdate.REGISTRATION_ID);
if (txns.ITEM_NAME == "Standard Settlement Configuration Id")
{
regDetailsToUpdate.STANDARD_SETTLEMENT_CONFIGURATION_ID = txns.ITEM_VALUE;
if (String.IsNullOrEmpty(txns.ITEM_VALUE))
{
//display error msg -> item valu
return Json(new { success = false, validinput = false, message = "Please enter the Standard Settlement Configuration Id" }, JsonRequestBehavior.AllowGet);
}
else
{
int i = 0;
string s = txns.ITEM_VALUE;//"0393"
bool result = int.TryParse(s, out i);//0393
if (!result == true)
{
ModelState.AddModelError(txns.ITEM_VALUE, "Not Valid SSC");
}
}
}
_repository.Save();
return Json(new { success = true, validinput = true, message = "Updated details Successfully" }, JsonRequestBehavior.AllowGet);
}
}
catch (Exception e)
{
}
return Json(ModelState.ToDataSourceResult());
}
如果用户输入字符而不是数字，我想显示验证消息。如何在Controller中使用kendo显示验证错误消息？
尝试更换
return Json(ModelState.ToDataSourceResult());
与
return Json(new []{ txns }.ToDataSourceResult(request, ModelState), JsonRequestBehaviour.AllowGet);
您要在数据源请求中传递ModelState和request返回。
在网格本身中，您需要引用DataSource的Error方法
.DataSource(datasource => datasource
.Ajax()
.Events(e => e
.Error("Grid_Error") // Can be named anything but it's usually best to add the suffix '_Error'
)
现在，您需要的是一个名为javascript的JavaScript函数，它可以打印以下错误：
function Grid_Error(e){
if(e.errors){
var message = "There are some errors:\n";
// Loop through the errors you defined in the controller
$.each(e.errors, function(key, value){
if('errors' in value)
{
$.each(value.errors, function(){
message += this. '\n';
})
}
})
alert(message);
// Here you can simply cancel the changes using the datasource, reverting the grid back to its original state.
}
}
注意：如果此网格是局部网格，则可能需要将此javascript函数上一级，放在父级的cshtml中
