Hi Friends,

I am using VS 2013,Javascript.
I have a gridview with 4 checkbox.When I check on first checkbox,other 3 checkboxes are checked.But when I uncheck the first check box,other 3 checkboxes should be unchecked.But unchecking of 3 checkboxes are not coming .
<asp:CheckBox ID="chkInclude" runat="server" EnableViewState="true" >

What I have tried:

C#

 protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            CheckBox chkInclude = (CheckBox)e.Row.FindControl("chkInclude");
            CheckBox chkCreate = (CheckBox)e.Row.FindControl("chkCreate");
            CheckBox chkChange = (CheckBox)e.Row.FindControl("chkChange");
            CheckBox chkDelete = (CheckBox)e.Row.FindControl("chkDelete");

            chkInclude.Attributes.Add("OnClick", "checkAllCheckBoxTrue(document.getElementById('" + chkInclude.ClientID + "'),document.getElementById('" + chkCreate.ClientID + "'),document.getElementById('" + chkChange.ClientID + "'),document.getElementById('" + chkDelete.ClientID + "'),document.getElementById('" + GridView1.ClientID + "'))");
           

        }
    }<pre lang="Javascript"><pre>function checkAllCheckBoxTrue(viewid, createid, changeid, deleteid, grid) {
    
    for (i = 1; i < grid.rows.length; i++) {

           
        id1 = grid.rows[i].cells[3].childNodes[0];
       
        
        if (id1.checked = false)
        {
            
            createid = grid.rows[i].cells[4].childNodes[0]; // get
            changeid = grid.rows[i].cells[5].childNodes[0]; // get
            deleteid = grid.rows[i].cells[6].childNodes[0]; // get
            
            createid.checked = false;
            changeid.checked = false;
            deleteid.checked = false;

          
        }
        else if (id1.checked = true) {
          
            createid.checked = true;
            changeid.checked = true;
            deleteid.checked = true;

            createid.disabled = false;
            changeid.disabled = false;
            deleteid.disabled = false;
           
        }
    }
   
}

if (id1.checked = false)
if (id1.checked = true)

Use "==" to compare, and "=" to assign. Change these to

if (id1.checked == false)
if (id1.checked == true)

There might be other issues in your code, I haven't tried it

Solution 1

Write the complete check handling as handler of the include checkbox.

In your function must must correct the comparison to "=="

I think you should simply do this, so that your are not using negative comparison. Also, notice that I have moved your code which is enabling check boxes before the code setting checkboxes to checked.

if (id1.checked)
{
createid.disabled = false;
changeid.disabled = false;
deleteid.disabled = false;

createid.checked = true;
changeid.checked = true;
deleteid.checked = true;

}
else
{
createid = grid.rows[i].cells[4].childNodes[0]; // get
changeid = grid.rows[i].cells[5].childNodes[0]; // get
deleteid = grid.rows[i].cells[6].childNodes[0]; // get

createid.checked = false;
changeid.checked = false;
deleteid.checked = false;
}
