Unsolved Parser Error "server tag...", help...

Undead Lumberjack · Apr 28, 2012

Hi, I had explaint this error last friday, but I hadn't put the code, so I'll do this time; The problem was that i'm trying to add a column to the left of my datagrid, the text of that column is "delete" so I can use it later with this command, But it don't work, because I can't even see the column added; instead I get the following error: Server Error in '/' Application. -------------------------------------------------------------------------------- Parser Error Description: An error occurred during the parsing of a resource required to service this request. Please review the following specific parse error details and modify your source file appropriately. Parser Error Message: The server tag is not well formed.

ataGrid id="DBAddDataGrid" runat="server" Line 136: Width="100%" Line 137: BackColor="white" I think this must be a little problem of syntax, aniway I'm working with a standard html editor and not with vb.net ...

I'm sure this is just a little error, but I can't debugg it. Thanks a lot for your time!! From Spain. Salvador Gallego. Try This: <ASP

ataGrid> Just had to rearrange some brackets

])ryLike the Error Says: Your tags are not well formed. Looking at what you are trying to accomplish, the basic structure should be something like: <asp:dataGrid> ?<columns> ??<asp:itemTemplate> ???<asp:Button /> ??</asp:itemTemplate> ?</columns> </asp:dataGrid>Using MaintainState="false" I don't get the "server tag..." error yet, but I get this other one instead: Server Error in '/' Application. -------------------------------------------------------------------------------- Control 'DBAddDataGrid__ctl2__ctl0' of type 'Button' must be placed inside a form tag with runat=server. Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. Exception Details: System.Web.HttpException: Control 'DBAddDataGrid__ctl2__ctl0' of type 'Button' must be placed inside a form tag with runat=server. Source Error: An unhandled exception was generated during the execution of the current web request.

Stack Trace: [HttpException (0x80004005): Control 'DBAddDataGrid__ctl2__ctl0' of type 'Button' must be placed inside a form tag with runat=server.] System.Web.UI.Page.VerifyRenderingInServerForm(Con trol control) +151 System.Web.UI.WebControls.Button.AddAttributesToRe nder(HtmlTextWriter writer) +38 [etcetera...] I'm starting to think this may be something relationated with web.config or something, because it seem to be an easy task but I can't do it :-( Aniway thanks a lot ])ryWater and CristN, Any other options? Hope so... You don't gonna belive it, just putting the "</form>" tag under the datagrid code and deleting the "mantainstate=false" line, the code works also fluently... Aniway there are two things I still not understanding: A) Why the table doesn't show itself with the form load like happend before? B) What is the Explanation for just change that tag and avoid the error? Something related with runat="server" tag, probably :S... Thanks again. Salvador Gallego.It was the Internet Explorer cache settigs the reason why it failed, so; 100% Solved :-D Salvador Gallego.
