Hi,
I have a RadGrid that serves to show text for preview and editing. I have a detail aspx page which serves as the parent, and then user control pages within a radtabstrip with a multipageview. When I try to preview the text box within the grid (which is wihtin the usercontrol), I get a null each time I reference the window manager, the window comes back null. I have a piece of it working where I preview images, for some reason it reads tha manager fine. As you can see from the code below, I've tried a few things. Let me know if there's a viable solution to my problem. Again, informationWindowLocation works, and the OnClientPageLoad doesn't.
protected void ibPreviewMessage_Click(object sender, EventArgs e)
{
ImageButton previewMessage = (ImageButton)sender;
ClientScriptManager clientScript = Page.ClientScript;
//string clientScriptName="previewMessage";
Type clientScriptType=this.GetType();
int index = previewMessage.ID.IndexOf("_"), ID;
int.TryParse(previewMessage.ID.Substring(index + 1), out ID);
foreach (GridDataItem gdi in grdMessages.Items)
{
RadTextBox rtb = (RadTextBox)gdi["DefaultDescriptionNameColumn"].FindControl("Description_" + ID.ToString());
if (rtb != null)
{
radWindowManager1.OnClientPageLoad = "OnClientPageLoad('" + HttpUtility.HtmlEncode(rtb.Text) + "')";
RadWindow newwindow = new RadWindow();
newwindow.ID = "previewmessages";
newwindow.NavigateUrl = "about:blank";
newwindow.VisibleOnPageLoad = true;
newwindow.Behaviors = WindowBehaviors.Close;
radWindowManager1.Windows.Add(newwindow);
//if (!clientScript.IsClientScriptBlockRegistered(clientScriptType, clientScriptName))
//{
// StringBuilder sb = new StringBuilder();
// sb.Append("<script type='text/javascript'>");
// sb.Append("radopen('about:blank')");
// sb.Append("document.write(" + HttpUtility.HtmlEncode(rtb.Text) + ")");
// sb.Append("</script>");
// clientScript.RegisterClientScriptBlock(clientScriptType, clientScriptName, sb.ToString());
//}
//RadAjaxManager ajm = RadAjaxManager.GetCurrent(Page);
//if (ajm != null)
//{
// ajm.Alert(HttpUtility.HtmlEncode(rtb.Text)); // make this a radopen or a window.open
//}
}
}
}
<script type="text/javascript">
function informationWindowLocation(id) {
var oManager = GetRadWindowManager();
var fileName = "Images/" + id;
var examplePath = new Image();
examplePath.src = fileName;
var width = examplePath.width;
var height = examplePath.height;
var oWnd = oManager.GetWindowByName("messages");
if (width > 0 && height > 0) {
oWnd.Show();
oWnd.setSize(width + 100, height + 100);
oWnd.SetUrl(fileName, "messages");

the radwindow manager on the aspx page looks like this
I know that it has two radwindowmanagers on the same page, but I couldn't get the manager from the main page when I tried to search using the $find method. I also couldn't find the one on the user control. Let me know if there is anything I should do. Thanks
