RadGrid Popup Edit Form with RadWindow Issue

Hi All,
I have a page in which i am using the RadGrid to get data from database using the Advanced Databinding and custome edit form shown as popup for inserting and updating the data.

The update and insert are done using the UpdateCommand and InsertCommand events.

Everything is ok...

BUT

While Updating any record or inserting a new one, and before completing the update or insert, i need to show a message for the user depending on database check for some conditions....

I used the RadWindowManager on the page that holds the grid...

The window is shown correctly depending on the conditions...BUT i need to keep the popup edit form open after showing and closing this message window... in my page the popup is closed directly when showing the Window message....

i searched the forums and i found the this can be done if i set the

e.Item.IsInEditMode =

true

in the ItemUpdated event of the grid; but this event will not fire in my case...since i knew that this event will fire only in case of automatic operations is enabled.

so my question is how to keep the popup edit form open while updating???

any comment will be helpfull...

thanks in advanced...

Asa'ad...

refresh fires insertcommand

Why would a page refresh fire the grid's insertcommand? If you add a new row with auto-insert enabled and then right-click and refresh the screen it fires the insertcommand again. How can I stop this behavior?

Couple of AjaxManager Questions

Hi,

1. My page has many controls, I have surrounded logical UI groups of controls into asp:Panels and am using this outer Panel as the updated control in the ajaxmanager configuration. Is this correct? Or do I have to define the links to all lower level controls?

i.e.

<telerik:AjaxSetting AjaxControlID="compareproductLinkButton">
                <UpdatedControls>
                    <telerik:AjaxUpdatedControl ControlID="toprowPanel" />
                    <telerik:AjaxUpdatedControl ControlID="deptLiteral" />
                    <telerik:AjaxUpdatedControl ControlID="resultsPanel" />
                    <telerik:AjaxUpdatedControl ControlID="relatedcatsPanel" />
                    <telerik:AjaxUpdatedControl ControlID="activefilterPanel" />
                </UpdatedControls>
</telerik:AjaxSetting>

... etc

The reason I wanted to check is that on a given ajax postback a literal control in one of the panels is not updating even though in debug I can see the code being run. And I am seeing a few things dissappear on certain ajax postbacks.

2. If I define a control as part of an ajaxmanager relationship then its css style at run-time drops into block level (or something happens to change our css, I assume it is surrounded by a div for ajax update), how can I stop this happening?

Thank you
Matt

Reloading Treeview From Code Behind

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server"

EnablePageHeadUpdate="False">

<AjaxSettings>

<telerik:AjaxSetting AjaxControlID="lnkbutton">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="RadTreeView1" />

</UpdatedControls>

</telerik:AjaxSetting>

</AjaxSettings>

</telerik:RadAjaxManager>

lnkbutton is the ID of button which is in RadTreeview1 .

<telerik:RadTreeNode Value="pcomment">

<NodeTemplate>

<telerik:RadTextBox runat="server" Width="250px" ID="postcomment"></telerik:RadTextBox>

<asp:Button Text="Post" runat="server" ID="lnkbutton" onclick="lnkbutton_Click" ></asp:Button>

</NodeTemplate>

</telerik:RadTreeNode>

Code - Behind

protected void RadTreeView1_NodeExpand(object sender, RadTreeNodeEventArgs e)

{

string getc =

"SELECT  [User].Name, [User].ID, Comments.ID AS CID, Comments.Comment, Comments.ItemID, Comments.UID, [User].T28 FROM            [User] INNER JOIN Comments ON [User].ID = Comments.UID WHERE        (Comments.ItemID = 271)"

;

dt = dbClass.ReturnDT(getc);

if (dt.Rows.Count > 0)

{

int n = dt.Rows.Count;

for (int m = 0; m < n; m++)

{

RadTreeNode onDemandNode = new RadTreeNode();

onDemandNode.ImageUrl = dt.Rows[m]["T28"].ToString();

onDemandNode.Text = "<u><b><a href='Profile/profile.aspx?Id="+dt.Rows[m]["ID"].ToString()+"'>"+dt.Rows[m]["Name"].ToString()+"</a></b></u> "+ dt.Rows[m]["Comment"].ToString();

onDemandNode.ExpandMode = TreeNodeExpandMode.ClientSide;

//Add the node as a child of the currently expanded node

RadTreeView1.Nodes.FindNodeByText("Comments").Nodes.Add(onDemandNode);

}

}

     }

 protected void lnkbutton_Click(object sender, EventArgs e)

    {

       RadTextBox tb=  (RadTextBox)RadTreeView1.Nodes.FindNodeByValue("pcomment").FindControl("postcomment");

       string insertcomment = " INSERT INTO Comments (ItemID, UID, Comment) VALUES  (271, "+Session["UserId"]+", '"+tb.Text+"')";

       dbClass.DataBase(insertcomment);

      

    }

What I want is ,whenever the user clicks the button post that is the button with ID lnkbutton , the RadTreeView1 gets refreshed (without reloading the whole page again) , what should i do to achieve this ??

Open Radwindow from Global.asax file

Dear All,

Please let me know if its possible to open RadWindow using severside code from Application_start event of Global.asax. I am trying to open the radwindow in a callback method of cache item whenever the cache item expires. Please find the code below for your reference. Any help will be appreciated.
