[Solved] Window popup location on very long page

I have a very long report that uses RadWindow popups to allow the user to edit data. However, when the user is a ways down in the report and clicks on a button in the row in which they're looking to open the RadWindow, although the screen grays out, the popup opens above or below where the user is actually looking. I am assuming the window is opening mid-way down/up the page, and if the user isn't at that point, they have to scroll to look for it.

Is there a way to set the location of the RadWindow so that it is centered in the screen where they've opened it?

Thanks!

RadWindow and RadTab

I am having a strange problem when trying to show a RadWindow every time a user click a RadTab.

This happens in codebehind when the user click a tab and an internal condition is true:

string strScript = "radconfirm('Save?', confirmCallBackFn, 430, 110, null, 'Save');";
ScriptManager.RegisterStartupScript(this, this.GetType(), "rtsFallvilt", strScript, true);

If I at the same time remove the mouse pointer from the clicked tab everything works fine, but if the mouse pointer is left standing over the tab that was clicked the radconfirm is shown but togheter with a javascript error saying "unspecified error".

When I debug the error is in the ScriptResource.axd on this line "_45.setActive();"

Any idea?

format string with a url and multiple items??

hello is it possible to have a Groupbyexpression render as a link? I would like to be able to pass the friendly name to the user and the recordid in the url. something like <a href=# onclick=openRadWindow('1105512'); return false;>2009 Mazda Miata</a>
This is my current group by expression and format string .. however you will note I have used {0} for both instances.

Would LOVE to see : Mazda Miata: Avaialable: 1
RENDERS AS: RecordID: 80329; Available: 1

    
            <GroupByExpressions>   
        
            <telerik:GridGroupByExpression> 
        
            <GroupByFields> 
        
            <telerik:GridGroupByField FieldAlias="Description" FieldName="RecordID" /> 
        
            </GroupByFields> 
        
            <SelectFields> 
        
            <telerik:GridGroupByField FieldName="RecordID" FormatString="<a href=# onclick=openRadWindow('{0}'); return false;>{0}</a>" /> 
        
            <telerik:GridGroupByField FieldName="Countitem" Aggregate="Count" HeaderText="Available"/>  
        
            </SelectFields> 
        
            </telerik:GridGroupByExpression> 
        
            </GroupByExpressions>

The current string does work to popup the information (I have no idea how without any quotes...) , however I really would prefer to see the description.
thanks

Export to excel not working

Hi Telerik
I am using RadGrid but due to pre-design excel template i am doing export to excel function using below code. It is working fine. but when i deployed it on relience server then it is not working. even not generating any error also.
code :

public

void ExcelExport(System.Data.DataTable tblExportData, string TempFilePath,string userInfo,bool headerStatus)

{

try

{

Microsoft.Office.Interop.Excel.

Application excelApp = new Microsoft.Office.Interop.Excel.Application();

excelApp.Workbooks.Open(TempFilePath,

Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing);

//Writing Header in Excel

if (headerStatus == true)

{

for (int i = 0; i < tblExportData.Columns.Count; i++)

{

excelApp.Cells[7, i + 1] = tblExportData.Columns[i].ColumnName;

}

//Writing Data in Excel

for (int i = 1; i <= tblExportData.Rows.Count; i++)

{

for (int j = 0; j < tblExportData.Columns.Count; j++)

{

string colName = tblExportData.Columns[j].ColumnName;

excelApp.Cells[i + 7, j+1] = tblExportData.Rows[i-1][colName];

}

//Create a worksheet object

Microsoft.Office.Interop.Excel.

Sheets sheets = excelApp.Worksheets;

//from the collection of worksheet select one worksheet

Microsoft.Office.Interop.Excel.

Worksheet mySheet = (Microsoft.Office.Interop.Excel.Worksheet)sheets.get_Item(1);

//select the cell in the worksheet

Microsoft.Office.Interop.Excel.

Range myCell1 = (Microsoft.Office.Interop.Excel.Range)mySheet.get_Range("A6", "A6");

myCell1.Value2 = userInfo;

myCell1.Font.Color = System.Drawing.Color.Black.ToArgb();

excelApp.Visible = true;

}

catch (Exception ex)

{

}

}

since export to excel button is grid command item so i am handling postback operation using this code.

if

(e.Item is GridCommandItem)

{

GridCommandItem item = (GridCommandItem)e.Item;

ImageButton ibtn = item.FindControl("imgbtnExport") as ImageButton;

ibtn.OnClientClick =

String.Format("{0}.__doPostBack(\"{1}\",\"{2}\");return false;", RadAjaxManager1.ClientID, ibtn.UniqueID, ibtn.CommandArgument);

}

and now in exporttoexcel button click event i am calling above function.
in case of local server it's working fine in all system. but once it deployed in another server (e.g. Reliance Server) it's not working.

please help me to achieve my result.
thanks a lot in advance.

Refresh TreeView inside Splitter

I am on a deadline and sincerely need any help!

HOW to Refresh the selected node of a treeview, inside a splitter, by calling it from the contentPane.

I have a splitter. Within the Splitter, on left pane I have the TreeView. This Treeview has sections (section1, section2...). Each section has %complete calculation coming from the database. On the right pane is the contentPage, where user fills data and saves it to the database. Each time user fills and saves the data in the rightPane/contentPage. I want the selected node in the treeview to be refreshed.

Any help is appreciated.

Here is my code:--

<telerik:RadSplitter BorderSize="0" style="overflow:hidden" id="RadSplitter1" Skin="Outlook" runat="server" Height="700px" width="100%">
        <telerik:RadPane id="RadPane1" runat="server" width="250" CssClass="PanelBarBackground">
            <div class="tree-module">
            <table cellpadding="0" cellspacing="0">
            <tr><td colspan="3"> </td></tr>
            <tr>
                <td width="5px">&nbsp</td>
                <td>
                     <telerik:RadTreeView ID="RadTreeView1" OnClientNodeClicked="OnClientNodeClicked" runat="server" Skin="Blue"
                     EnableEmbeddedSkins="False" OnPreRender="RadTreeView1_PreRender" SingleExpandPath="true">
                    <DataBindings>
                        <telerik:RadTreeNodeBinding Target="ctl00_MiddleContent_ContentPane" />
                    </DataBindings>
                </telerik:RadTreeView>
                </td>
                <td width="5px">&nbsp</td>
            </tr>
             <tr><td colspan="3"> </td></tr>
            </table>
            </div>
        </telerik:RadPane>
        <telerik:RadSplitBar Visible="true" id="RadSplitbar1" runat="server" collapsemode="Forward"></telerik:RadSplitBar>
        <telerik:RadPane id="ContentPane" runat="server" ContentUrl="about:blank" Scrolling="None">

DockToggleCommand client side

I have looked through the forums but have been unsuccessful in finding a solution for my problem.

I have created a dock with a multipage control inside it, the first page has a grid which shows some data and the second page has a chart which shows the data in bar chart format. i have been successful in adding a RadTabStrip inside the doc and controlling the pages this way.

What I want is a custom toggle button on my dock title bar to change the multipage and change the image client side. I have been successful in implementing this with a postback and just changing the state of the toggle button and changing the page, but i can not find a solution for doing this client side.

I see that i might have to write Javascript, but i am a novice at writing script.

How can i do this?

thanks

Using ItemTemplate with Transparent PNG in IE

I'm having troubles getting the rotator to do what it obviously should in IE. I have a horizontal rotator that uses button clicks to advance the rotator. The items in the rotator is dynamic based on the user (some users may have 15-20 items, some may only have 1).

Each item template contains one PNG image that is links to another website. Each image is a circle (like an M&M) that has a transparency in the PNG to fade to the background (it's a gradual fade with different degrees of transparency, different than a GIF).

It looks fine on first load, but as soon as I scroll either left or right, each item that is displayed has a horrible reaction with the transparency.

I'm using IE7, but it looks fine in both FireFox3 and Safari for PC. I also noticed that if I do a GIF with a transparent background it works fine, but I can't make it look as nice :)

I have a zipped project with example images I was going to attach, but doesn't look doable. It is available if anyone needs it to help.
