Hi

We are currently experiencing a problem with our grid control when a user switches their language to anything other than en-GB.

The problem is occurring when we hit the search button twice and the columns of the grid attempt to resize, using an auto resize JS function we have registered on the page. This function should resize the columns to the size of the values in the columns themselves.

I have attached the code I believe the problem exists. Can you provide a possible fix for this issue?

function AutoResizeColumns() 
	{
	    var gridMinWidth = 0;
 
	    var grid = window['grid_' + '<%= grd.ClientID %>'];
	    for (var i = 0; i < grid.MasterTableView.Columns.length; i++) {
 
	        var maxColumnSize = 0;
            
            for (var j = 0; j < grid.MasterTableView.Rows.length + 1; j++) {
                var gridRow = j < grid.MasterTableView.Rows.length ? grid.MasterTableView.Rows[j].Control : grid.MasterTableView.HeaderRow;
 
                var textContent = "";
                if (gridRow.cells[i].childNodes.length > 0 &&
                (typeof gridRow.cells[i].childNodes[0].getElementsByTagName == "function" || typeof gridRow.cells[i].childNodes[0].getElementsByTagName == "object")) {
                    var childNodes = gridRow.cells[i].childNodes[0].getElementsByTagName("span");
                    if (childNodes.length > 0) {
                        textContent = childNodes[0].innerText;
                    }
                }
 
                if (textContent != null) {
                    var rowColLength = textContent.trim().length;
                    if (rowColLength > maxColumnSize) {
                        maxColumnSize = rowColLength;
                    }
                }
            }
 
            if (maxColumnSize > 0) {
                gridMinWidth += (maxColumnSize * 7.5);
                grid.MasterTableView.ResizeColumn(i, maxColumnSize * 7.5);
            }
            else {
                gridMinWidth += 2;
                grid.MasterTableView.ResizeColumn(i, 2);
            }
	    }
 
	    document.getElementById(grid.ClientID).style.width = "100%";
	    document.getElementById(grid.MasterTableView.ClientID).style.width = "100%";
 
	    document.getElementById(grid.ClientID).style.minWidth = gridMinWidth + 100;
	    document.getElementById(grid.MasterTableView.ClientID).style.minWidth = gridMinWidth + 100;
	}

Dear Support,

I'm trying to follow your example here and set up a web part that utilizes all the features.  My problem is getting the ajax scripts running.  I followed the instructions from this thread, and also I tried registering the scripts from this article.  So far I'm registering the following:



The callbacks only work if I put the RadScheduler control on the page and nothing else.  Once I start adding the other elements from the example, I can't use any of the built-in functionality, like collapse/expand the left pane, scroll through dates, switch scheduler views, etc.  Please help!

I'm using the build version=2011.2.712.35.

Thank you,

Dasha.

I have a VERY simple RibbonBar on an othewise blank test page that is throwing a JavaScript error: "object does not support this property or method" in the dynamically generated Telerik WebResource file. Here is the source code of the page. The only code behind is the button click handler which has no code in it. What am I calling out on the Ribbon that is not supported?? See the attached screenshot for the debugger capture.

Hi All

I have a grid that is using static headers with columns declaring widths using the header.width property. However I have no control over the grid size by resizing my columns,  as resizing one column stretches out the other so the grid fits the whole page, like it is auto resizing to fit the page. Any Ideas on how to have control of grid widths greatly appreciated.

I implemented an Outlook Web Access type mailbox using RadGrid eons ago and have only had to perform minor maintenance over the years. It is currently using Q1 2011 controls and has been limited to single row selections. I capture the client side rowclick event and perform a callback to the server passing the newly selected index as an argument. Server side I reset the colour of the previously selected row (grid.SelectedItems[0]) and unselect it, then darken the colour of the newly selected row (the index of which was passed as an argument in the callback), selecting it server side.

My client now wants to enable multirow select (to delete multiple emails, for example). I would of course like to do this with as few changes as possible, but during the callback, the server does not know whether the newly selected row is part of a multiple selection or a single selection, so it does not know whether the previously selected row needs to be unselected or not. Is there any argument that I can pass to the server as part of the callback which indicates whether the ctrl key was depressed at the time of the new selection (or, even better, an attribute of the grid that shows which is the current selection "mode")? If not, what's the best way of reading all selected row indexes client side so that I can pass an argument array to the server?

Many thanks.

Hi,

I have tried implementing multiple comboboxes (2 comboboxes) from example
http://mono.telerik.com/Combobox/Examples/Functionality/MultipleComboBoxes/DefaultCS.aspx

Its working fine. Now If I set the selected value like

FirstcomboBox.SelectedValue = somevalue

for 1st combobox (on page load) I want to fire event to load the 2nd combobox currently which is not working. Do I need to set any property for this?


Thanks,
Balaji

hi,
i have radgrid whic contains checkboxes, this rad grid is placed inside an xmlhttppanel whic is placed inside an ajax panel. A button is placed inside the ajaxpanel ,like shown above
no under the 'OnClick' (server side) event of the button am tracking the selected checkboxes, this doest works for the first button click. but it works after the first click ... any solutions..?

I have created a RadGrid dynamically and added it to a placeholder at Page_Init event.

I'd need to add a custom button to the CommandItem and for this I've tried many scenarios and none of which has worked properly:

1) I added the custom button at RadGrid_ItemCreated event. The button appears. When it's clicked, it posts back, however, its click event handler is never raised. why? how to fix it?

My button is a normal ASP.NET button:

private Button CreateExportToPdfButton()
        {
            var result = new Button();
            result.ID = "btnExportToPdf";
            result.Click += ExportToPdfButtonClick;
            result.CssClass = "rgExpPDF";
            result.CommandName = "ExportToPdfCustomCommand";
            result.Attributes["title"] = "Export to Pdf";
            return result;
        }

Also I tried managing it in the ItemCommand event when the button is clicked: 

protected void RadGrid1_ItemCommand(object sender, GridCommandEventArgs e)       

{

    if(e.CommandName == "ExportToPdfCustomCommand")

    {

        //my code here

    }

}

but ItemCommand event doesn't get raised either when the button is clicked.

2) I added the custom button at RadGrid_MasterTableView_Load. The button appears and when it's clicked, it posts back and click event is raised as expected which is great. As soon as sorting is enabled on the RadGrid and a column header is selected to be sorted, the sorting happens however my custom button disappears. Why? how to fix it?

3) On RadGrid_MasterTableView_Init; behaves similar to #2

4) On RadGrid_MasterTableView_PreRender; behaves similar to #1

5) On RadGrid_Init, behaves similar to #2

6) Another possible approach comes to mind is to create a new CommandItemTemplate: http://www.telerik.com/help/aspnet/grid/grdcommanditemtemplate.html

in which case, the click event and itemcommand events are raised properly.

But there is an issue with this approach that it would be more complex as I'm using the built-in Export to Word and Excel functionalities of RadGrid currently. so not sure how to add these 2 to the CommandItemTemplate this way?

I'd rather making the previous approaches working if possible.

Your help is very much appreciated on any of these approaches.

Hello,

I try to implement custom filter control like here. I put a textbox and button into template column and everything now shows fine in filter row. But I need to set custom button which will contain fully custom filter menu. I want it to display when I press the button and send a filter command  when menu item is selected. But right now I can't event start built-in filter menu. I tried to add button onclick event like on your demo page, i.e.
$find("RadGrid1")._showFilterMenu("RadGrid1_ctl00", "ContactName", event); return false; __doPostBack('RadGrid1$ctl00$ctl02$ctl02$Filter_ContactName','')
but I always get a JS error  here:

this._buildFilterMenuItemList(this._filterMenu,f._data.FilterListOptions,f._data.DataTypeName,f._data.CurrentFilterFunction,f);

If I translate it to English, it's going to be like "Cannot get a value for _data; it's not defined or has a null value". Something like this.
So I have 2 questions:
  a. Is this possible to display built-in filter menu when clicking on custom button inside a filter template?
  b. Is this possible to built a fully custom menu and make it work the same way as built-in?
Thank you.
