can i choose somewhere not to make that happen?
so i don't have to tab all over again?That's real odd. Mine does the opposite. It auto tabs and makes everything look purty. :)
I guess this would entail deleting the last page from the linked list that the browser holds for pages that I do not wish to revisit.
Is this possible?Because of security reasons, you can't get the history from the client.
I was developing an ASP.NET web application..and suddenly..i got hungry...i saved everything and closed Visual Studio.Net (2003) ..ate...back to VS.NET..start my application...then..i got this error
Visual Studio cannot create or open the application because the web server on this computer is not running. Start the web server before processing.
Now,this is my whole story..i did nothin to VS ..what should i do
(i found that the web server is running..i stopped it..then restarted it..but in vain...un then re install the iis....restart windows (XP pro) ..and i got the same error)
try running the regiis, that sometimes fixes the problem and you should do it after re-installing iis.
C:\WINNT\Microsoft.NET\Framework\v1.1.4322\aspnet_regiis.exe -i

You may just re-start your IIS server.
i tried everything...aspnet_regiis.exe /i ...stop and restart...remove the IIS and add it again..then aspnet_regiis.exe /i ...
As title, druing a button-click post back, I set a control, say Button1, to get the focus by Button1.Focus();
However, after the page is rendered, the Button1 still do not gets the focus as if browser window itself gets the focus instead.
Could any body give me some tips the find out the problem?
Note: The page is copied from an existing one and do some modification.
Thanks a lot
Ricky

it could be that the page is focusing somewhere else due to javascript, or just the browser...
but if you add the following code to your page, you should be able to re-focus where you want it... (add this code at the bottom of your page with the Page.ClientScript.RegisterStartupScript method):
setTimeout(function() { document.getElementById("myTextBox's Client Side ID here...").focus(); }, 250); <-- this will do it after 250 milliseconds (adjust to your needs).
Peace,

Hi everyone,
I'm having a problem with using the DropDown list control in ASP.NET 2.0 and the selected item name not being retained in the control. I have this control on a MasterPage and when you select Blue I do a Response.Redirect to a content page. The problem is I'd like the DropDown list control to retain the name Blue, but it doesn't work it always displays the blank from "" after you make your selection. I have ViewState enabled as well as AutoPostBack on the DropDown list control set to true. If I set AutoPostBack to false, then the selected name is retained, but the Response.Redirect doesn't fire. Please note below:
//MySiteMasterPageprotected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
ColorsDropDownList.Items.Add("");
ColorsDropDownList.Items.Add("Red");
ColorsDropDownList.Items.Add("Green");
ColorsDropDownList.Items.Add("Blue");
ColorsDropDownList.Items.Add("Yellow");
}
}protected void ColorsDropDownList_SelectedIndexChanged(object sender, EventArgs e)
{
switch (ColorsDropDownList.SelectedValue)
{
case"Red":
Response.Redirect("~/Red.aspx",false);
break;
case"Green":
Response.Redirect("~/Green.aspx",false);
break;
case"Blue":
Response.Redirect("~/Blue.aspx",false);
break;
case"Yellow":
Response.Redirect("~/Yellow.aspx",false);
break;
}
}
I have searched thorough the forums for similiar issues, but everything I've tried either hasn't worked or was not close enough to my situation.
Thank you,
What you need to understand about Viewstate isthat it is only applicable within a single page during postbacks; thatis, once you switch pages, all the page data from the prior page isgone.
However, if you must redirect to adifferent page for each color -- and I'm not sure you have to do that,since you could easily make one dynamic page -- you can hard-code theselected value of the DDL for each page. That is, if you're onthe Blue page, youknow the user picked Blue, so you can just set it when the page loads.
Cheers,
I may not have explained this properly. First I tried to pick colors as a simple example; however, the actual application is for a reporting application. There is a MasterPage that contains the TreeView control showing the reports the user is able to access based on their user role. The DropDownList control represents various departments. When the user selects one of the reports they have access to it is displayed in the TreeView it displays the department page with the selected report. Following what you suggested by hard coding I'm not following how to set the DropDown control manually to the department page name that was selected from the DropDownList control.

Ok, yes trying your example does work; however, I am not doing a Response.Write("~/Red.aspx");. I am doing a Response.Redirect("~/Red.aspx", false) to send the user to a page called Red.aspx. Actually this is just an example and not the actual name of the page the user is be redirected to.
Is it possible to get the same effect as using Response.Write, but instead use Response.Redirect??
Thanks,
Lance
When you do a Response.Redirect, all the ViewState information is lost. You need to use a different type of session state to keep track of the value
You could store the value in a session variable and then after the response.redirect read from it
Session["ddlIndex"] = ddlDropDownList.SelectedIndex;
Response.Redirect("otherpage.aspx");
On the other page you would do this
ddlDropDownList.SelectedIndex = (int)["ddlIndex"]
Thanks for the reply James. I see what you are saying, but when I try to compile this I receive a few errors on the line on the other page.
ddlDropDownList.SelectedIndex = (int)["ddlIndex"];
Invalid expression term '['
; exprected
; expected
Invalid expression term ']'
How do I fix this? Also that above line will still maintain the name of the item that was selected from the drop down list control even though the control resides on the Master Page and this is just a content page??
Thanks
It should be ddlDropDownList.SelectedIndex = (int)Session["ddlIndex"];
I didn't check the code so it may have minor syntax errors like forgetting the ; terminator.
Ok, i should have caught that Session was missing also. That takes care of that problem, but I still have an issue with the Drop Down List Control. The name doesn't exist in the current context, because it is located on a different page.
