I have a user control with a datagrid and few other information on title and summary. I would like to render this control to an Excel file !
The problem is , as soon as i try to open the rendered xls file, Excel reports an error, that the file extension is not valid, and that it is not from a trusted resource.
I'm using code similar to code mention at http://www.dutch-creatives.com/post/2009/08/11/Export-ListView-to-Excel.aspx
to export Listview to excel

I tried to debug, understand why it is generating an extra tr td but couldn't.How Can i directly cast item into HTMLTablerow?
Two separate questions, but sufficiently intertwined that I'm going to try the two together....
Firstly - User Controls and Behaviours
I have a User Control which contains a few visual controls. I am attaching some behaviours by using GetScriptDescriptors and am passing some JavaScript to the browser using GetScriptReferences. That is all rock solid and working well. However, when developing, I did discover that I couldn't attach the ehaviours to the User Control itself - not surprising as rendering a User Control does not create a DOM element which represents the actual control. So, I have attached my behaviours to a "random" TextBox within the User Control.
So - first question, is there a better way to do that? For example, should I always be rendering a SPAN as an element to surround the control? Not sure what that would do to the robustness of the rendering. What is the right way to attach a behaviour to a User Control.
Secondly - Accessing those same Behaviours later
Assume I have placed a User Control on the page. That User Control exposes a Property (actually a Javascript Function of course) which does "something" to the control - for the sake of example we'll say that the function is set_Border(colour). I then have a behaviour on the same page (actually an Extender on a different control) which needs to call the function. I have a reference to the User Control in my script, so I have tried TheControlReference.set_Border('red') and find that my control doesn't support the set_Border method.
I guess this is probably because the behaviours are not attached to the User Control itself, but to a GUI element within it. Hence, I suspect that the answer to the second question lies within the answer to the first.
I am using two user controls in my page. The controls are loaded dynamically one at a time. I'm just referencing the user controls in the page and loading them dynamically using 'LoadControl()'. Everything is working fine till now and the user can switch the controls one another.
Here the issue I found is eventhough the controls are working as expected and the data is visible, the rendered HTML contains only the first loaded user control's markup.
Even if the current control displayed is 'usercontrol2', the source shows 'usercontrol1' markup. How can I force the page to render 'usercontrol2' markup and remove 'usercontrol1' markup while loading'usercontrol2'?
I have Two Datalist Control . One is dtlistCat and second is dtlistSeries. dtlistSeries is filled by dtlistCat by dtlistCat_ItemDataBound method .
Coding side is ok . But Only problem in rendering . I want the page render with dtlistSeries has 2 repeat column in verticle direction I think only designning part creating problem .Not proper width or height specified so.
ViewSeries.aspx
<%@ Page Language="C#" MasterPageFile="~/MasterPage/Store.master" AutoEventWireup="true"
I render some markup dynamically in a Web User Control, can I get that out in design mode, and not only runtime?
public override void RenderControl(HtmlTextWriter writer)
{
if (this.DesignMode)
writer.Write("<p>In design mode</p>");
else
base.RenderControl(writer);
}
... nothing happens when I check the design view of the control. Not if I remove the if (this.DesignMode)-condition either.
ASP.NET 2.0 application exports GridView data to Excel2003 as shown below, but then needs to be able to access the Excel instance; to add a title row, auto-fit column widths, rename the worksheet, etc. Can anyone explain/show how to reference the Excel instance programmatically?
Response.ClearContent()
Response.AddHeader("content-disposition", "attachment;filename=MyFile.xls")
Response.ContentType = "application/vnd.ms-excel"

I want to export evrything in a page to excel, it's just the graph that does not export. I used WebChart Control graph which I downloaded [URL]. I've been looking around and found that you must use SaveImage(), but I do not have that option.
protected void excel_Click(object sender, EventArgs e)
{
excel.Visible = false;
Response.ContentType = "application/ms-excel";
Response.AddHeader("content-disposition",
"attachment; filename=CashFlow.xls");
}
How would you troubleshoot a page that is rendering slowly in ASP.NET?
This issue is happening on only specific pages with a few user controls. Other pages work fine. Tracing has clarified that the issue is happening between "Begin Render" and "End Render".
I have an SSRS report that has a Comments field where there's enough text to span multiple rows per record. It renders fine in the ASP.Net ReportViewer control, but when it's exported the formatting can be different. Exporting to Word it looks fantastic. But exporting to Excel and PDF, the row height for each record is never increased beyond the default, so the text just gets truncated. In Excel I can go in and double-click on individual or multiple row heights to fix them, but this is an extra step we don't want.
View 2 Repliesi have try to export data to excel using gridview.
I have export it successfully but some data is missing which is due to the column format in the exported excel file is not TEXT .

I need to set the exported excel file column format to TEXT but find no solution on this.
I would like to use the gridview paging feature and have built a gridview with a user control. The data source has lots of columns, so to make it easier I want to return a LIST<MyObject> and just pass <Myobject> into the user control rather than all the data elements. Not sure how I access the object of the data source to bind to the control. Assume it would be during ondatarowbound.
Also, my guess is there is a better way to do this than gridview. I'd take either solution that allows me to have easy paging and pass the complete object into the user control
How can I export data from a Gridview to excel and once exported the data should be formatted in right to left (arabic) manner. How can I achieve this?
View 2 RepliesWe have the requirement to export the data from the grid excel. We can't install the Excel on the server. The excel generated need to be in the printable format. The excel generated needs to have custom headers, footers, repeatble rows, columns and landscape / portrait orientation style.

when I used a code of exporting gridview into excel this code worked for a new website which is without masterpage.
my code:
public override void VerifyRenderingInServerForm(Control control) { }
protected void BtnGenerateReport_Click(object sender, EventArgs e)
{
Response.Clear();
Response.Buffer = true;
Response.AddHeader("content-disposition",
"attachment;filename=GridViewExport.xls");
Response.Charset = "";
Response.ContentType = "application/vnd.ms-excel";
StringWriter sw = new StringWriter();.....
Now the same code when I copy it in my project having masterpage . there is no compiler error but it is genereating excel file withno data in it but in fact there is data in the grid view at runtime.

View 1 RepliesI have a calendar control where a user selects a date and then inputs info into a FormView control. Underneath the FormView is a GridView that shows all data from the SelectedDate on the calendar control. However, when the date is selected, all the information from the table ( from all dates ) is displayed.

I don't think I understand fully how ASP.NET does inheritance of controls.I have a user control, ucBase, which has an asp.net label in the ascx file. Code behind references the label and it works fine during run time if the control is not a parent for another user parent.
If I have another user control, ucChild, inheriting from ucBase, the label in ucBase's code is always null. ucChild has no controls in its ascx fileThe server controls (like the label) needs to be declared in the ascx file and not created programmatically.What needs to be done for ucBase to see its own controls when it's a parent user control?
Is there any way to prevent the asp:Login control from rendering a table around my controls? Rendered HTML: <div id="credentials">
View 12 RepliesI have a repeater control which has an table format that has textboxes in it. I tried the solution at [URL] which works but loses the table format. I have an example below in which I have modified that code and have it so now the table format stays but the values show outside the table and not in the correct columns and rows.
I need to keep the values in the proper location.
<asp:Repeater ID="rptMonthlyReport" runat="server" OnItemDataBound="rptMonthlyReport_ItemDataBound">
<HeaderTemplate>
<header>
<asp:Label ID="lblOne" runat="server">Monthly Performance Report</asp:Label>

I'm rewriting my website in aspx to pull text from a SQl server and pop it up in a modal. I have everything working fine, but when I was using plain asp and HTML tables, I was able to format some of the text in the database using HTML tags, and they would render to screen. Is there anyway to do the same thing when using the following:

The RenderControl() raises the aforementioned exception. Has anyone succeeded in doing something similar.
