Re: how to find gridview hidden label value from javascript

Hi,

if you set the label control to visibility=false then it won't get rendered. Use a <asp:HiddenField> control instead.

but i want to hide gridview column how can i do that. If i am using template field visible false then again same situation occured.

Re: how to find gridview hidden label value from javascript

Hi,

mamtagupta
using template field visible false

As I said before, when you set it to Visible=false, it won't get rendered to the browser. Use a hiddenfield instead or use css to make the column invisible.

Grz, Kris.

Re: how to find gridview hidden label value from javascript

css can hide a dynamic grid column. If you have that css code please provide me.

Re: how to find gridview hidden label value from javascript

Hi,

in css create a class like

.hideColumn { display:none; }

and set it on the column template like CssClass="hideColumn"

Hi,

mamtagupta
thanks its working.

No problem.

mamtagupta
But i have one more problem

It's best to start a new thread for that and refer to another thread if necessary. Adding on top of resolved questions with new questions makes a thread less transparent.

Start a new thread and explain in more detail what you're after, what your rendered code looks like or what code you already have.

Grz, Kris.

Re: how to find gridview hidden label value from javascript

U can try this:

var trObject = document.getElementById(your tr Id);

var inputs = trObject.getElementsByTagName("INPUT");

inputs appear as an array

it's not new thread. It's same here i am finding gridview row with tr tag.

Re: how to find gridview hidden label value from javascript

Have you tried using jQuery? If you haven't you can find any element on the page by a selector. So if you want to find a hidden field called hdnField you would do this:

$("#hdnField").val();

That would return the value of the hidden field.

Can you show us some piece of your generated html? jQuery could indeed help you to find what you're after. I suggest you take a look at its selectors: http://docs.jquery.com/Selectors.

Re: how to find gridview hidden label value from javascript

Try this jQuery. It will only search for a field that ends with hbEmployee_Id:

$("input[id$=hbEmployee_Id]").val()

The $= section of the selector works well in these scenario's where the id is changed thanks to master pages for example.

Re: how to find gridview hidden label value from javascript

hi malcolms,

i have this javascript method

function CheckOtherIsCheckedByGVID()
    {
        var Parent = document.getElementById('ctl00_ContentPlaceHolder1_ctl02');
        var itemchk = Parent.getElementsByTagName('TR');
        var val_ret='';
        for(var i=0;i<itemchk.length;i++)
        {
            var itemch=itemchk[i].getElementsByTagName('INPUT');
            for(var k=0;k<itemch.length;k++)
            {
                if(itemch[k].type=="checkbox")
                {
                    if(itemch[k].checked)
                    {


                        var emp= itemchk("input[id$=hbEmployee_Id]").val();
                        alert(emp);
                                                        

                    }
                }
            }
        }
    }

will you please help because I don't know how can i use this.

Re: how to find gridview hidden label value from javascript

Well that piece of JavaScript will return the value of the hidden field. So if you only have one hidden field named that, that piece of code will find it without looping through each row in the table. Make sense?
