Hi,

In Google chrome browser, when user increases grid column size on client side, grid does not re size so it does not show right columns and it does not show horizontal scroll bar as well. I use Telerik.Web.UI.dll released on 02-Apr-2013 version 2013.1.403.35.

HTML page code.

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>

<%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>

//$(document).ready(SetObject);

$(window).resize(SetRADGrid);

function SetRADGrid() {

var grid = document.getElementById(rdgrdGenericReportClientID);

var windowHeight = $(window).height();

var windowWidth = $(window).width();

var gridHeight = 0;

var contentPageHeight = 510;

var pageHeaderAndFooter = 125;

var gridHeader = 75;

gridHeight = windowHeight - pageHeaderAndFooter < contentPageHeight ? contentPageHeight - gridHeader : windowHeight - gridHeader - pageHeaderAndFooter;

grid.style.height = gridHeight + "px";

var webSiteWidth = 1024;

var submenuWidth = 231;

var gridWidth = windowWidth < webSiteWidth ? webSiteWidth - submenuWidth : windowWidth - submenuWidth;

grid.style.width = gridWidth+ "px";

//grid.repaint();

}

function GridCreating(sender, eventArgs) {

SetRADGrid();

}

function ColumnResized(sender, eventArgs) {

//alert('hi');

SetRADGrid();

}

</script>

public string Name { get; set; }

public string ClassName { get; set; }

public string Marks { get; set; }

Please find attached same sample code without telerik dll.

Hi Jigar,

In your example you set width for the columns in code behind, but the total width of the grid is greater than the total width of all columns, so they re-size to fill all the space and are not 100px wide anymore. This leads to the described behavior. In order to avoid this you can either delete this line:
e.Column.HeaderStyle.Width = Unit.Pixel(100) , or set the RadGrid's width to be equal to the total width of all columns or less.

Sample.zip

Hello Jigar,

I am sorry for the misunderstanding.

You can easily achieve the desired functionality without any additional scripting, just by setting AllowColumnResize, ResizeGridOnColumnResize and AllowScroll properties to true, as you already did and add the following CSS rule to your page styles:

#rdgrdGenericReport {

width: 900px !important;

}

This will prevent the grid from changing its width and horizontal scroll bar should appear when the total width of the columns exceeds the width of the grid.

Additionally, I saw some mistakes in the provided code. Firstly the line
var grid = document.getElementById(rdgrdGenericReportClientID); retrieves an html DOM element and stores it into grid variable. After that you try to repaint the grid: grid.repaint() which is not possible and you'll get a javascript error. In order to repaint the grid you need to get its client-side object instead. You can do that either by using the sender object which is internally passed to the event handler SetRADGrid on grid created:

JavaScript:

function SetRADGrid(sender, eventArgs) {

var

grid = sender;

....

sender.repaint();

}

or like follows:

var grid = $find("<%=rdgrdGenericReport.ClientID %>");

Please refer to this help topic: Getting Familiar with Client-side API which will provide more detailed information. Also it is not recommended to set the same attributes twice:

<ClientSettings Resizing-AllowColumnResize="true" AllowDragToGroup="True">

<Resizing AllowColumnResize="True" ResizeGridOnColumnResize="true"></Resizing>

<Scrolling AllowScroll="true" />

<ClientEvents OnGridCreating="SetRADGrid" OnColumnResized="SetRADGrid" />

</ClientSettings>

I also attach a sample project to illustrate the approach.

I hope this helps.

RadGridResizing.zip

Hello Marco,

Jigar's question concerned a specific requirement where RadGrid should show a horizontal scroll bar when the total width of all columns become greater than the width of the grid. However the problem you mention in your post is different. It appeared with version 30 of Google Chrome and we are aware of it. The fix will be included in the service pack.

Please find attached a sample project that includes the mentioned fix. However I should warn you that the test for it are not completed yet. If you decide to contribute and test it on your side too, we will be very grateful to receive your feedback.
