I want to fix(Freeze) gridview header while vertical scrolling.
I also want to fix first column while horizontal scrolling.
I want this in both chrome and IE.
It is possible to apply the specific GridView / Table layout via custom CSS rules (as it was discussed in the <table><tbody> scrollable? thread) to fix GridView's Header. However, this approach will not work in all browsers. The 3-rd ASP.NET GridView controls (such as the ASPxGridView from DevExpress component vendor provide this functionality.
Check also the following CodeProject solutions:
Fixed header Grid
Gridview with fixed header
Gridview Fixed Header
I was looking for a solution for this for a long time and found most of the answers are not working or not suitable for my situation i also find most of the java script code for that they worked but only with the vertical scroll not with the horizontal scroll and also combination of header and rows doesn't match.
Finally i have found a solution with javascript here is the link bellow :-
scrollable horizontal and vertical grid view with fixed headers
Refer Here which is 100% working

Static Header for Gridview Control
You can try overflow css property.

Acheived by using java script...
Copy and paste given below javascript code inside the head tag.
<script language="javascript" type="text/javascript">
function MakeStaticHeader(gridId, height, width, headerHeight, isFooter) {

}
}
function OnScrollDiv(Scrollablediv) {
document.getElementById('DivHeaderRow').scrollLeft = Scrollablediv.scrollLeft;
document.getElementById('DivFooterRow').scrollLeft = Scrollablediv.scrollLeft;
}
</script>
Then Copy this code and paste and place your Grid View inside DivMainContent.
HTML Code:-
<div id="DivRoot" align="left">
<div style="overflow: hidden;" id="DivHeaderRow">
</div>
<div style="overflow:scroll;" onscroll="OnScrollDiv(this)" id="DivMainContent">
<%-- ***Place Your GridView Here***
<asp:GridView runat="server" ID="gridshow" Width="100%"
AutoGenerateColumns="False"ShowFooter="True">
<Columns>
//...................
</Columns>
</asp:GridView>
--%>
</div>
<div id="DivFooterRow" style="overflow:hidden">
</div>
</div>
Then Call function MakeStaticHeader in Aspx.CS File at the time of binding Gridview and pass the Some parameters.
ClientId of Gridview(Change GrdDisplay.ClientID as your gridview clientid).
Height of Scrollable div.
Width of Scrollable div.
Height of Table Header Row.
IsFooter (true/false) If you want to Make footer static or not.
-->After binding the Gridview, place below code
ScriptManager.RegisterStartupScript(Page, this.GetType(), "Key", "<script>MakeStaticHeader('" + GrdDisplay.ClientID + "', 400, 950 , 40 ,true); </script>", false);
Hope this will work for sure...

I would like to request the Like Button status of each post (by ID) that is appended by Infinite Scroll.
<li class="post text" id="{PostID}">
The Tumblr Documentation provides this method of checking the status of a Like Button for individual posts:
Tumblr.LikeButton.get_status_by_page(n)
Description: Call this function after requesting a new page of Posts. Takes the page number that was just loaded as an integer.
Finally, here is the Infinite Scroll script (Proto.jp modified by Cody Sherman):
$(document).ready(function() {

You need to offset the div so it appears over the marker. An offset of (-5, -30) works for this marker and the number "1".
function TxtOverlay(pos, txt, cls, map, offset){
this.pos = pos;
this.txt_ = txt;
this.cls_ = cls;
this.map_ = map;
this.offset_ = offset;
this.div_ = null;
this.setMap(map);
}
TxtOverlay.prototype.onAdd = function(){
var div = document.createElement('DIV');
div.className = this.cls_;
div.innerHTML = this.txt_;
this.div_ = div;
var overlayProjection = this.getProjection();
var position = overlayProjection.fromLatLngToDivPixel(this.pos);
div.style.left = ( position.x + this.offset_.x) + 'px';
div.style.top = ( position.y + this.offset_.y)+ 'px';
var panes = this.getPanes();
panes.floatPane.appendChild(div);
}
TxtOverlay.prototype.draw = function(){
var overlayProjection = this.getProjection();
var position = overlayProjection.fromLatLngToDivPixel(this.pos);
var div = this.div_;
div.style.left = ( position.x + this.offset_.x) + 'px';
div.style.top = ( position.y + this.offset_.y)+ 'px';

txt = new TxtOverlay(latlng,customTxt,"customBox",map,new google.maps.Point(-5,-30) )

I have wriiten a javascript which I am using it onblur event of textbox which is inside a gridview. The same script should fire for me when I perform SelectedIndexChanging of gridview. This is my script
<script type="text/javascript">
function total(txtQuantity, txtRate, txtAmount) {
var col1;
var totalcol1 = 0;
var weight = document.getElementById(txtQuantity).value;
var rate = document.getElementById(txtRate).value;
var tot = weight * rate;
document.getElementById(txtAmount).value = tot.toFixed(2).toString();
var grid = document.getElementById('<%=grdInvoice.ClientID %>');
for (i = 0; i < grid.rows.length; i++) {
col1 = grid.rows[i].cells[4];
//col2 = grid.rows[i].cells[1];
for (j = 0; j < col1.childNodes.length; j++) {
if (col1.childNodes[j].type == "text") {
if (!isNaN(col1.childNodes[j].value) && col1.childNodes[j].value != "") {
totalcol1 += parseInt(col1.childNodes[j].value)
}
}
}
}
document.getElementById('<%= lblTotal.ClientID %>').innerHTML = totalcol1.toFixed(2).toString();
document.getElementById('<%=lblResultbalance.ClientID%>').innerHTML = totalcol1.toFixed(2).toString();
document.getElementById('<%=TextBox1.ClientID%>').value = totalcol1.toFixed(2).toString();
}
Can some one help me
Try this in your event
ScriptManager.RegisterStartupScript(this, GetType(), "script", "total('" + txt1.ClientID + "','" + txt2.ClientID + "','" + txt3.ClientID + "')", true);
I have 4 tables that need to scroll, they are set up as follows:
Table1(static)
Table2(Horizontal Scrolling)
Table3(Vertical Scrolling)
Table4(Horizontal and Vertical Scrolling)
Table1 Table2
Table3 Table4
The tricky part of this is that Table 3 and 4 need to keep in sync as this is a listing of data broken out into two tables. Table 2 and 4 are in the same situation.
Any ideas?
No Javascript please as we have a script that works, but it is far too slow to work.
Thanks.

We got the code from this link.
I hope this helps.
As it stands, the code is far too bulky to process the amount of data we need to. We have approximately 5000 rows of data per month that needs to be displayed on the page.
If by "need to keep in sync" you mean that when you scroll one of them, the other scrolls too, you can't do this with CSS, because you can't manipulate scroll position using CSS.
And one more thing, have in mind that scrollbar in IE goes inside the element and overlaps 20px of this element (there is a workaround for this), and in all other browsers scrollbar goes outside the element.
You can use CSS to set the height of an element and then set overflow:auto (this will give you scroll bars when needed).
Its very hard to get rows of a table to scroll properly. I've been trying with things such as wrapping a table row in a div (or vice versa) and setting a max-height and overflow of that div.
That's the best I can do with out seeing what you are trying to do.
function ResizeCells(table, cornerDiv, headerRowDiv, headerColumnDiv, bodyDiv)
{
var childElement = 0;
if (table.childNodes[0].tagName == null)
{
childElement = 1;
}
SetWidth(
cornerDiv.childNodes[childElement].childNodes[childElement].childNodes[0].childNodes[childElement],
headerColumnDiv.childNodes[childElement].childNodes[childElement].childNodes[0].childNodes[0]);
SetHeight(
cornerDiv.childNodes[childElement].childNodes[childElement].childNodes[0].childNodes[childElement],
headerRowDiv.childNodes[childElement].childNodes[childElement].childNodes[0].childNodes[childElement]);
var headerRowColumns = headerRowDiv.childNodes[childElement].childNodes[childElement].childNodes[0].childNodes;
var bodyColumns = bodyDiv.childNodes[childElement].childNodes[childElement].childNodes[0].childNodes;
for (i = 0; i < headerRowColumns.length; i++)
{
if (headerRowColumns[i].tagName == "TD" || headerRowColumns[i].tagName == "TH")
{
SetWidth(
headerRowColumns[i],
bodyColumns[i],
i == headerRowColumns.length - 1);
}
}
var headerColumnRows = headerColumnDiv.childNodes[childElement].childNodes[childElement].childNodes;
var bodyRows = bodyDiv.childNodes[childElement].childNodes[childElement].childNodes;
for (i = 0; i < headerColumnRows.length; i++)
{
if (headerColumnRows[i].tagName == "TR")
{
SetHeight(
headerColumnRows[i].childNodes[0],
bodyRows[i].childNodes[childElement],
i == headerColumnRows.length - 1);
}
}
}
function SetWidth(element1, element2, isLastColumn)
{
// alert(element2 + "\n\n" + element2.offsetWidth);
var diff = paddingLeft + paddingRight;
if (element1.offsetWidth < element2.offsetWidth)
{
element1.childNodes[0].style.width = element2.offsetWidth - diff + "px";
element2.childNodes[0].style.width = element2.offsetWidth - diff + "px";
}
else
{
element2.childNodes[0].style.width = element1.offsetWidth - diff + "px";
element1.childNodes[0].style.width = element1.offsetWidth - diff + "px";
}
}
function SetHeight(element1, element2, isLastRow)
{
var diff = paddingTop + paddingBottom;
if (element1.offsetHeight < element2.offsetHeight)
{
element1.childNodes[0].style.height = element2.offsetHeight - diff + "px";
element2.childNodes[0].style.height = element2.offsetHeight - diff + "px";
}
else
{
element2.childNodes[0].style.height = element1.offsetHeight - diff + "px";
element1.childNodes[0].style.height = element1.offsetHeight - diff + "px";
}
}
function SyncScroll()
{
for (i = 0; i < arrayCount; i++)
{
headerRowDivs[i].scrollLeft = bodyDivs[i].scrollLeft;

}
}
I appoligize, this part will not format no matter what I do, sorry about the poor formatting.
