i am not able to download the file. and not able to disable ajax. the file is saved in db in byte format

message - Error: Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed. Common causes for this error are when the response is modified by calls to Response.Write(), response filters, HttpModules, or server trace is enabled.
Details: Error parsing near '��JFIF'.

Access filter container from Page_Load

Hi,

I have a fully programmatically implemented Radgrid, with filters enabled. When you implement a Filter Template Class (to make a custom filter), you have to implement the function InstantiateIn, which has the container as a parameter. In this function you add the components of your Filter Template to this container, but I want to add controls to the container from outside this function. Is it possible to find this container form the Page_Load function? I've serached everything, and I have seen that you can get it at ItemCreated or ItemDataBound, I don't exactly remember. But this is not what I want, I want to get it from Page_Load. How can I do that?

Thanks

RadGrid virtualization and Editing

Going through the radgrid documentation there is a limitation that we cannot use the BatchEdit or inplace Mode with virtualization.

What is the alternate or workaround to that?

My client do not want to use paging but want to provide the editing feature on the GRID which has thousands of records. Additionally performance has to be handled as number of records in the GRID can be of order of 000's so definitely need to use virtualization or paging.

Any suggestion on to get around this and achieve this functionality.

TreeView is not getting refreshed when I bind it from AjaxManager_AjaxReqest

Dear Team,

I'm displaying hierarchical data using Treeview. We need to change the datasource of treeview dynamically based on user input. I'm using the below code do achieve the functionality:

In ASPX:

function LoadTreeView(projectid) {

var ajaxManager = $find("<%= RadAjaxManagerforGrid.ClientID %>");

ajaxManager.ajaxRequest("treeview_databind," + projectid);

}

In Code behind:

protected void RadAjaxManagerforGrid_AjaxRequest(object sender, AjaxRequestEventArgs e)

{

string[] arguments = e.Argument.Split(',');

if (arguments[0] == "search")

{

string _search = arguments[1];

int result = BindProjectData(false, _search);

if (result == 0)

{

Label lblEmptyMessage = RadListView1.Controls[0].FindControl("lblmessage") as Label;

lblEmptyMessage.Text = "No records to display.";

}

else if(arguments[0] == "treeview_databind")

{

int? folderId = Convert.ToInt32(arguments[1]);

BindFolderTreeViewData(folderId);

hdnSelectedFolderId.Value = arguments[1];

ScriptManager.RegisterClientScriptBlock(this, typeof(Page), "alertScript", "$('#video-move').modal('show');", true);

}

BindFolderTreeViewData() Method:

protected void BindFolderTreeViewData(int? folderId)

{

if(folderId!=null)

{

RadTreeFolders.Nodes.Clear();

List<Folder> lst = DomainDAL.GetFolderHierarchy(folderId);

RadTreeFolders.DataSource = lst;

RadTreeFolders.DataFieldID = "FolderID";

RadTreeFolders.DataFieldParentID = "ParentFolderID";

RadTreeFolders.DataValueField = "FolderID";

RadTreeFolders.DataTextField = "FolderName";

RadTreeFolders.DataBind();

}

Treeview is not getting refreshed/not displaying any data. Can you please help

Thanks,

Phani

Customized Yaxis range

Is it possible to customize the range that is displayed on my Yaxis? If the recordset populating the chart has numbers from 75,000,000 - 85,000,000, I don't want to start at 0 but say have my range be 65,000,000 - 95,000,000. But the range can change based upon the data being returned. It would be nice to have my range be 10% of the minimum value and maximum value. Something else is that my values returned may also be a percentage.

Also on my Xaxis I will be displaying dates. How do I only show the labels where the month is a quarter end (3, 6, 9, 12)?

Thanks

Installing a previous version of controls

I recently upgraded one of our projects to a more recent version but it had issues, so I downgraded it to a previous version (2011Q1).

One of my programmers here did not have Q1 on his computer so I told him to install and when he tries he receives a message saying he has a more recent version installed and the install stops.

Is there a way to install a previous version of the controls?

I know different version can live on the same machine, my currently computer has the last 4 versions (plus a few versions of Radcontrols for ASP.Net). But I've upgraded all versions in the right order, not installed a previous version in the middle.

Thanks
