I know how to call a client-side javascript function to get parameters to pass to the the controller for the various actions of a grid. But what if I need to call a javascript function that itself takes a parameter? How to I pass a value from the grid's action, data methods to the javascript function?

Thank you in advance for your advice.


//grid setup...

  .Create(update => update.Action("Add", "MyController).Data("GetParams"))
  .Update(update => update.Action("Update", "MyController").Data("GetParams"))
...

function GetParams(fSomeFlag) {
  var retVal;
  if (fSomeFlag = true)
    retVal = "someValForCreate";
  else
    retVal = "someValForUpdate";

    return {
        param1 : retVal,
        param2: "someOtherValue"
    };

Hello Patrick,

 

Thank you for writing to us.

It would be best if you get this fSomeFlag externally. Generally, you can use the $("#grid").data().kendoGrid.dataSource approach to get the instance of the grid and its datasource.

Can you share an example where this fSomeFlag value will come from? Then, I can send you a more precise and accurate solution.

Thank you for the reply, Eyup. I should have been more clear in the intent of fSomeFlag. I was hoping to reuse the javascript function GetParams for both the grid's Create and Update functions. So, I was hoping of being able to tell GetParams whether it was the Create method or Update method calling the function. So maybe the flag should have been fCalledByAdd: 


function GetParams(fCalledByAdd) {
  var retVal;
  if (fCalledByAdd = true)
    retVal = "someValForCreate";
  else
    retVal = "someValForUpdate";

    return {
        param1 : retVal,
        param2: "someOtherValue"
    };
