Posted on by Habeeb-Dynamics CRM...

Hi,

I have created a button using HTML web resource then trigger some event on that button like hiding tabs, sections and grid.

below is the code:

parent.Xrm.Page.ui.controls.get('Select_Address').setVisible(false);
parent.Xrm.Page.ui.tabs.get("general").sections.get("general_section_5").setVisible(false);

But i am getting error: Uncaught TypeError: Cannot read property 'setVisible' of null.

The above code is working fine in CRM 2016 but when i was in CRM 2015 MS released some patches that's why it is not working since.Please help.

Note: section and tab names are correct.

Right,

Seems like your variable parent is null, or parent.Xrm.Page.ui.controls.get('Select_Address') are null.

You can debug your code (F12 Debugger) to check your values, or post your full code, to give more information to us.

Best Regards,

function updateDataToBillToLoc()

{

//get Grid Data

var grid =parent.Xrm.Page.getControl("Select_Address");

//get Selected rows

var selectedRows = grid.getGrid().getSelectedRows();

//get selected Row Count

var selectedRowsCount = selectedRows.getLength();

if (selectedRowsCount !=0)

{

//hide update button and grid control

document.getElementById("billToUpdateButton").style.visibility = "hidden";

parent.Xrm.Page.ui.controls.get('Select_Address').setVisible(false);

parent.Xrm.Page.ui.tabs.get("general").sections.get("general_section_5").setVisible(false);

var rowData = selectedRows.get(0).getData();

var entity = rowData.getEntity();

var attributes = entity.getAttributes();

//fetch sub grid attribute values to variables

var name = attributes.get("name").getValue();

var line1 = attributes.get("line1").getValue();

var city = attributes.get("city").getValue();

var stateorprovince = attributes.get("stateorprovince").getValue();

var postalcode = attributes.get("postalcode").getValue();

var data= name + "\n" + line1 + "\n" + city + "," + stateorprovince + " " +postalcode ;

parent.Xrm.Page.getAttribute("address1_name").setValue(name);

parent.Xrm.Page.getAttribute("address1_line1").setValue(line1);

parent.Xrm.Page.getAttribute("address1_city").setValue(city);

parent.Xrm.Page.getAttribute("address1_stateorprovince").setValue(stateorprovince);

parent.Xrm.Page.getAttribute("address1_postalcode").setValue(postalcode);

/* if (name == null || name == undefined)

{

parent.Xrm.Page.getAttribute("new_address1info").setValue("--");

parent.Xrm.Page.ui.controls.get('Select_Address').setVisible(false);

parent.Xrm.Page.ui.tabs.get("general").sections.get("general_section_5").setVisible(false);

return;

}*/

parent.Xrm.Page.getAttribute("new_address1info").setValue(data);

parent.Xrm.Page.getAttribute("new_address1info").setSubmitMode("always");

}

else

{

alert("No rows selected");

}

}

this is the full code and the "Select_Address" is Address grid and it is not null. I have debugged already.

either parent.Xrm.Page.ui.controls.get('Select_Address') or parent.Xrm.Page.ui.tabs.get("general").sections.get("general_section_5") is null.

better introduce an if loop before applying setvisible

like if(parent.Xrm.Page.ui.tabs.get("general").sections.get("general_section_5") !=null)

Also please change all selectors to small case.

You will get this error, if the field is not available or the schema name is different.

Hey There,

I ran into the same issue as you did! It was very confusing because I could call methods from the namespace Xrm.Page.Ui.* from the browser console but not from the specific JS code I wanted to use it in.

In my specific scenario... I was trying to call this from an async method. What happened is when that async code was executed it didn't know about Xrm.Page (page == undefined from this async context). As a result, the code would crash with an error "Cannot read property of blah" but I could read it from the console without issue.

Try moving your XRM.Page.* calls to outside of any async code, store these values and pass them to the method you need them in.

Hope this helps (someone)

Hi,

Try using window.parent.Xrm.Page.ui.controls.get('Select_Address');

Also if you are opening html webresource in a popup you may need to get Xrm using : window.top.opener.Xrm.Page.ui.controls.get('Select_Address');

Hope this helps:)
