I am having checkbox in datagrid and treeview, while click the button i need to check the checkbox in datagrid alone(how to differenciate checkbox in datagrid and treeview) using javascript

hi
try this.

function OnTreeClick(evt)
{
var src = window.event != window.undefined ? window.event.srcElement : evt.target;
var isChkBoxClick = (src.tagName.toLowerCase() == "input" && src.type == "checkbox");
if(isChkBoxClick)
{
var parentTable = GetParentByTagName("table", src);
var nxtSibling = parentTable.nextSibling;
if(nxtSibling && nxtSibling.nodeType == 1)//check if nxt sibling is not null & is an element node
{
if(nxtSibling.tagName.toLowerCase() == "div") //if node has children
{
//check or uncheck children at all levels
CheckUncheckChildren(parentTable.nextSibling, src.checked);
}
}
//check or uncheck parents at all levels
CheckUncheckParents(src, src.checked);
}
}
function CheckUncheckChildren(childContainer, check)
{
var childChkBoxes = childContainer.getElementsByTagName("input");
var childChkBoxCount = childChkBoxes.length;
for(var i = 0; i<childChkBoxCount; i++)
{
childChkBoxes[i].checked = check;
}
}
function CheckUncheckParents(srcChild, check)
{
var parentDiv = GetParentByTagName("div", srcChild);
var parentNodeTable = parentDiv.previousSibling;

if(parentNodeTable)
{
var checkUncheckSwitch;

if(check) //checkbox checked
{
var isAllSiblingsChecked = AreAllSiblingsChecked(srcChild);
if(isAllSiblingsChecked)
checkUncheckSwitch = true;
else
checkUncheckSwitch = true; //do not need to check parent if any(one or more) child not checked
}
else //checkbox unchecked
{
checkUncheckSwitch = true;
}

var inpElemsInParentTable = parentNodeTable.getElementsByTagName("input");
if(inpElemsInParentTable.length > 0)
{
var parentNodeChkBox = inpElemsInParentTable[0];
parentNodeChkBox.checked = checkUncheckSwitch;
//do the same recursively
CheckUncheckParents(parentNodeChkBox, checkUncheckSwitch);
}
}
}
function AreAllSiblingsChecked(chkBox)
{
var parentDiv = GetParentByTagName("div", chkBox);
var childCount = parentDiv.childNodes.length;
for(var i=0; i<childCount; i++)
{
if(parentDiv.childNodes[i].nodeType == 1) //check if the child node is an element node
{
if(parentDiv.childNodes[i].tagName.toLowerCase() == "table")
{
var prevChkBox = parentDiv.childNodes[i].getElementsByTagName("input")[0];
//if any of sibling nodes are not checked, return false
// if(!prevChkBox.checked)
// {
// return false;
// }
}
}
}
return true;
}


//utility function to get the container of an element by tagname
function GetParentByTagName(parentTagName, childElementObj)
{
var parent = childElementObj.parentNode;
while(parent.tagName.toLowerCase() != parentTagName.toLowerCase())
{
parent = parent.parentNode;
}
return parent;
}

hi

u can also try this simple method to check or uncheck the check box inside the gridview

protected void deleteAllArchiveLinkButton_Click(object sender, EventArgs e)
{
CheckBox deleteArchiveCheckBox;
try
{
foreach (GridViewRow j in archiveGridView.Rows)
{
deleteArchiveCheckBox = (System.Web.UI.WebControls.CheckBox)j.FindControl( "deleteArchiveCheckBox");
if ((((System.Web.UI.WebControls.CheckBox)j.FindContr ol("deleteArchiveCheckBox")).Checked) == true)
{

(((System.Web.UI.WebControls.CheckBox)j.FindContro l("deleteArchiveCheckBox")).Checked) = false;
}
else
{
(((System.Web.UI.WebControls.CheckBox)j.FindContro l("deleteArchiveCheckBox")).Checked) = true;
}
}

}
catch (Exception ex)
{

}
}
