[CLOSED] [Razor] Parameter passing from DirectEvents

[gets_gui]

Hi

I've created a combobox with a directEvent attached and defined the method in the controller which is called when the user selected a value.

What is the best way to either:

1) Pass the selected value into the Controller
2) Access the selected value directly from Controller

cshtml

@(
  Html.X().ComboBox()
    .ID("cbDirectEvent")
    .Text("ComboBox1")
    .Store(store => store.Add(
           ...
        ))
        .Model(model => model.Add(Html.X().Model()
          .Fields(fields =>
          {
              fields.Add(Html.X().ModelField().Name("Value"));
          })
        ))
      ))
    .DirectEvents(directEvents =>
    {
      directEvents.Select.Url = "/Controller/ValueSelect";
    })
    .DisplayField("Value")
    .ValueField("Value")
)

Controller Code

        
public ActionResult ComboBoxSelect()
{
  // Use selected value from combobox
}

Hi,

The best way would be sent a value via ExtraParams.

Example

@(Html.X().ComboBox()
    .DirectEvents(directEvents => {
        directEvents.Select.Url = "Test/ComboBoxSelect";
        directEvents.Select.ExtraParams.Add(new Ext.Net.Parameter() 
            { 
                Name="value", 
                Value="record.get(this.valueField)", 
                Mode = ParameterMode.Raw 
            });
    })
)

public ActionResult ComboBoxSelect(string value)

Thanks for the reply Daniil

I've got another related question. Is it possible to access other component values when passing parameters (2nd ExtraParam block)

      .DirectEvents(directEvents =>
      {
          directEvents.Select.Url = "/Shared/ComboBoxSelect";
          directEvents.Select.ExtraParams.Add(new Parameter()
          {
              Name = "parameter1",
              Value = "item.value",
              Mode = ParameterMode.Raw
          });
         directEvents.Select.ExtraParams.Add(new Parameter()
          {
              Name = "parameter2",
              Value = "document.getElementById('componentID').value",
              Mode = ParameterMode.Raw
          });     
      })

Please wrap the code in [CODE ] tags. It will improve its readability.

Thanks for editing.

This doesn't allow to access Ext.NET widgets.

document.getElementById('componentID')

You can access Ext.NET widgets directly by its client ids.

Example

Value = "App.componentID.getValue()"
