Key press event on more than one column in a grid.

[rowter]

Hello,

I have a grid with around 6 columns. I have a keypress event which allows only alphabets and numbers with some special characters. This code below works for me. However, I need the same keypress on more thant one column, Instead of repeating the same keypress event code under each column, I wanted to call a centralized function.

### Working Code:

{ name: "FundName", type: "text", width: 150, title: "Fund", filtering: false, editing: true, validate:[ "required" ], insertTemplate: function () { var valField = this._grid.fields[1]; var $insertControl = jsGrid.fields.text.prototype.insertTemplate.call(this); $insertControl.on("keypress", function (e) { if (e.which == 45 || (e.which > 47 && e.which < 58) || (e.which > 64 && e.which < 91) || (e.which > 96 && e.which < 123) || (e.which == 8) || (e.which == 32) || (e.which == 127)) { } else { e.preventDefault(); e.stopPropagation(); } }); return $insertControl; } }

### Modified code that does not work:

My modified code looks like below. If I use this code, when i click on insert, this particular column appears as read only field. I can type anything into it.

{ name: "FundName", type: "text", width: 150, title: "Fund", filtering: false, editing: true, validate:[ "required" ], insertTemplate: function () { var valField = this._grid.fields[1]; var $insertControl = jsGrid.fields.text.prototype.insertTemplate.call(this); AlphaNumericWithHyphenSpaceDeleteBackSpace($insertControl); }

function AlphaNumericWithHyphenSpaceDeleteBackSpace($insertControl) { $insertControl.on("keypress", function (e) { if (e.which == 45 || (e.which > 47 && e.which < 58) || (e.which > 64 && e.which < 91) || (e.which > 96 && e.which < 123) || (e.which == 8) || (e.which == 32) || (e.which == 127)) { } else { e.preventDefault(); e.stopPropagation(); } }); return $insertControl; }

I am not sure why this function call does not work. I do not see any errors on the browser. Can you point out if there is any mistake in my code?

Thanks in advance

in your code return for insertTemplate is missing, try with the return statement

var field = {
name : "FundName",
type : "text",
width : 150,
title : "Fund",
filtering : false,
editing : true,
validate : [ "required" ],
insertTemplate : function()
{
    var valField = this._grid.fields[1];
    var $insertControl = jsGrid.fields.text.prototype.insertTemplate.call(this);
 return   AlphaNumericWithHyphenSpaceDeleteBackSpace($insertControl);
}
}
