Just a quick question. Is it possible to store a control in the database such as <asp:label id="label1" runat="server" text="label1"></asp:label> into a database and render this on the page request?

You can store ASP.NET markup anywhere you want, including in a database. Controls can be generated dynamically using the Page.ParseControl[^] method.

Answers to these questions can be found by reading the Reporting Services documentation[^].
BTW, this question has nothing to do with ASP.NET. The ReportViewer component only provides a means of presenting a report. All logic is contained in the report definition which is stored on the Report Server. Reporting Services questions should be asked in the SQL forum.

Hi,
I am using a master page with all my normal .aspx files. How do I dynamically add javascript files to the head part of each .aspx page seeing that not all pages will use javascript?
What I mean is how would I add the following dynamically:
<script type="text/javascript" src="myjs.js"></script>
I use HtmlLink and HtmlMeta to set the link and meta tags dynamically, but how do I dynamically add script tags? I thought that there would be something like HtmlScript?
Thanks
Brendan

Use the RegisterClientScriptResource[^] method of the Page.ClientScript object to inject a script reference. Do this in your Master page.

HtmlTextWriter class is used to render the HTML to browser. This class is used to write the elements, attributes for different types of markup. Try using the below code(overide the render method of the page) to write the SCRIPT element to the page. Hope it works.
Protected Overrides Sub Render(ByVal writer As HtmlTextWriter)
writer.AddAttribute("type", "text/javascript")
writer.AddAttribute("src", "myjs.js")
writer.RenderBeginTag(HtmlTextWriterTag.Script)
MyBase.Render(writer)
writer.RenderEndTag()
End Sub

Hi,
Question:
Case 1: There are many C# client applications (eaxctly one C# windows application running on exactly one client machine, so cumulatively it many many client applcations) and one asp.net web server..
All these clients interact with web server independently..
Case 2: Same as case 1, many client applications, one web server but one difference.. There is a web service in between..
Which case has the best architecture and why???

Hi,
I have master page Website.master, and a Default.aspx that uses this master page. I will need to set the meta tags of each page dynamically. This was how I normally do it, but for some or other reason it does not work now:
Website.master.cs
public HtmlHead PageHeader
{
get { return (HtmlHead)Page.Header; }
}
public string MetaKeywords
{
set
{
HtmlMeta keywords = new HtmlMeta();
keywords.Name = "keywords";
keywords.Content = value;
PageHeader.Controls.AddAt(2, keywords);
}
}
Default.aspx.cs
Master.MetaDescription = "TEST";
The error that I keep on getting is:
The Controls collection cannot be modified because the control contains code blocks (i.e. <% ... %>).
I have no idea what I am doing wrong here??
Thanks
Brendan

AlphabetPagingTable.Rows[0].Cells.Clear();<br />

Table tab = AlphabetPagingTable;
if (tab != null)<br />
{<br />
for (int i = 65; i <= (65 + 25); i++)<br />
{<br />
<br />
<br />
LinkButton lb = new LinkButton();<br />
<br />
lb.Text = Char.ConvertFromUtf32(i) + " ";<br />
<br />
lb.CommandArgument = Char.ConvertFromUtf32(i);<br />
<br />
lb.CommandName = "AlphaPaging";<br />
lb.Click += new EventHandler(AlphabetPagingLink_Click);<br />
cell.Controls.Add(lb);<br />
tab.Rows[0].Cells.Add(cell);<br />
Label lbl = new Label();<br />

Hi!
How can I open a gridview in edit mode?
Normally if you open a website the gridview isn’t in edit mode. You can edit a row in gridview by clicking on edit button (edit link).
What I want is to open a website (with a grid) and all of the rows are in edit mode. You can edit a column and click on refresh or save.
Thanks in advance!
Best regards
Klaus

hi Klaus!
I think if you're using TemplateFields in GridView then you can put all the rows by default in edit mode. Actually there is a property called EditIndex. when you set it to a certain row number it changes itself to the edit template. so this is related to a single row you know. Since you want all the rows to be in edit mode. you need to craft this yourself by adding the text boxes etc
I hope it helps you
Thanks
Rocky

It goes something like this...
Thats only to show the use of Template Fields. You should carry on according to ur req from here
<asp:gridview id="GridView1" autogeneratecolumns="False" runat="server" datasourceid="ObjectDataSource1" horizontalalign="Left" width="205px">
BorderWidth="0px" CellPadding="0" >
<columns>
<asp:templatefield headertext="Refine Search">
<headertemplate>xyz
</headertemplate>
<itemtemplate>
<asp:textbox id="tb1" runat="server" Text='#Eval("DbField")'>
</asp:textbox></itemtemplate>
<footertemplate>
</footertemplate>
</asp:templatefield>
</columns>
</asp:gridview>
Hope that helps
Thanks

Hi,
You can try
//Index of the row to be edited.
GridView1.EditIndex = 0
GridView1.DataBind()

If I use your code, I get an error message, can you tell me why?
Here is my code:
public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
GridView1.EditIndex = 0;
GridView1.DataSource = "SqlDataSource1";
GridView1.DataBind();
}
}
}
Here is the error message:
System.InvalidOperationException was unhandled by user code

Hi,
As you have already defined DataSourceID and DataSource try your code like this
GridView1.EditIndex = 0;
GridView1.DataBind();
The error is generated probably because when you have already assinged DataSource and DataSourceID in designer and try to assign DataSource again in code it gives error.
