Hi

 How do I attach an OnFocus clientscript eventhandler to a dropdown in a WebGrid.... (.Type = ColumnType.DropDownList)

TIA

 Hi,

 Currently there is no such Onfocus client side event handler, but I hope you can use ClientSideEvents-CellClickHandler. You could also take a look at the other client side event in the grid (or in the WebCombo component itself) , and see if any other event suits your needs.

If none of the above helps, you could also submit a feature request , using the URL below:

Thank you for the feedback.

You could try embedding a webcombo intead of setting the column type. That way, you could cast the webCombo as a WebControl and add the Attribute onFocus:

WebControl web = (WebControl)WebCombo1;

web.Attributes.Add("onfocus", "function()");

This would call the function() when you enter editing the cell which has the WebCombo1 set as it's editorControl. I'm not sure if there's a workaround on this having the ColumType.DropDownList.

 I've tried using the following piece of script code (see below) and that seems to work nicely in IE. In FireFox however the dropdown object doesn't seem to exists when the beforeentereditmode exists.... any suggenstions to how I get hold of the dropdown in FireFox?

function cl_beforeentereditmode(gridid, cellid) {
    //Lets add a OnFocus handler to the DropDown in the cell, so we can set its item color
    var dropdown = ig_csom.getElementById(gridid + '_vl');
    if (dropdown!=null)
        ig_csom.addEventListener(dropdown, "focus", cl_dropdown_onfocus, true);       
  return false;
}
 

function cl_dropdown_onfocus() { //Lets set the color of each item in the DropDown
 
// Do my stuff

}

TIA
