How does this differ from qustion 1 ?
You need to use findcontrol recursively, there is no guarentee that a control will be on the top level. You fix that error by not writing code that assumes the search succeeds.

are you searching for the control within the page? if so try searching for it within your content panel or whatever holder you're using for it such as
mycontentpanel.controls.item(0).findcontrol(mycontrol).
|
|
|
|
|
please give me small sample code by which i can find or capture a control of a content page from master page.

If a control is always in the content, perhaps it belongs in the master page ?
this.Page.FindControl()

hi
i have made some of my columns in gridview invisible and now when i update my gridview the invisible column values are set to null
how can i update the gridview having invisible columns
madhu

You have to make that column visible before u r binding grid.After binding again u can make that column invisible.
Ex
GridEdit.DataSource = ds_projectSelect;
GridEdit.Columns[0].Visible = true;
GridEdit.DataBind();
GridEdit.Columns[0].Visible = false ;
hope that this will help u.

Hi,
Can I use <% = and %> tags to insert ASP.NET code snippets into my HTML? If yes? why doesn't the following code work?
<asp:RadioButton id="<% = r[i]["ID"].ToString() %>" runat="server" />
Also, if I use something like:
<asp:RadioButton id="SomeID" value="<% = r[i]["Value"].ToString() %>" runat="server" />
Any Ideas?

Yes...
signbit wrote: <asp:radiobutton id="<% = r[i][" id"].tostring()="" %="">" runat="server" />
But what is r in your code?
<< >>

|
|
|
Try this:
<%String val=r[i]["ID"].ToString();>
<asp:RadioButton id="SomeID" value="<%=val%>' runat="server" />
If this does not work, use double quotes instead on single quotes.
r must be a public member.

Error 104 The name 'window' does not exist in the current context

Nope...those are javascript methods...Do you know how to how to use js function?
<< >>
|
|
|
|

rougly by the way can u comfirm if my thinking is correct
asp.net2 code behind files are handled at server means the calculation made in the code behind file are made at server side
where by the java script is made at client side?
|
|
|
|
|
However, in code behind you can generate javascript code to execute at client side...

How do I get javascript such as that listed below to be read in an ASP file before the command <%response.redirect iurl(url)%>
<%id = request("id")
sql = "Select * from listings where id ="&id
open_recordset rs,SQL
hits = rs("hits") + 1
sql ="update listings set hits ="&hits&" where id = "&id
conn.execute(sql)
url = rs("url")
closelink(rs)
closeDB()%>
<%response.redirect iurl(url)%>
At the moment it just redirects to the new page without executing the javascript.
If I remove <%response.redirect iurl(url)%> then the javascript is read, however when I add <%response.redirect iurl(url)%> the javascript is ignored and it just redirects to the new page. Any ideas why this is happening?

Where do u want to call that java script function?Could u please be little bit clear?

I want to Develop a Database programe with Asp.net.
i put a datagrid in a page, and press a button to show a dialog page . I can input a new record in the page, and save it, Close it .
Can i refresh the datagrid page automatically? How can i do it ?
thanks
|
|

When you input a new record, and you save it, it must do a postback, so the page will refresh. If you close the page, then you have closed the page, there is nothing to refresh, but if you saved the data, any user can go back to that page and see the new data.
I therefore do not understand your question.

Hi,
Can you tell me how do u close the dialog page?
If you are using window.close() method in javascript to close the window then modify the javascript as following.
window.opener.location.reload();
window.close();
the first line will reload the the window from where u have open the dialog page.
I hope this will help you.
Thanks and Regards,

just do like from the child page.
function exitChildWin() {
window.opener.reload();
window.close();
}
just call the exitChildWin javascript function from the child page.

 We are looking for some assistance to get all aspects of our web application working on the web server.
Just to give a brief overview, we have created an application which allows people to sign up to use our general classifieds section. Upon clicking the submit button, the application inserts the record into the appropriate table in our MSSQL database, creates a new sub-folder for the user, using their username, and the creates two more sub-folders (one to store images and one to store PDF files) under the Username's folder.
The registered user can search the classified listings and the results pane shows a small thumbnail and decription. The user can click on the thumbnail to view more details. The problem we are experiencing is the display of the thumbnail and image.
Prior to this we had problems in uploading the image to the server in the following function:
private void SaveImages()
{
if (Session["UserType"].Equals("Customer"))
{
if (FileUpload1.FileName != "")
/* {
ResizeImage(300, 300, FileUpload1.PostedFile.FileName, Server.MapPath("~\\Customer\\" + Session["username"].ToString() + "\\Classifieds_Images\\") + FileUpload1.FileName);
ResizeImage(300, 300, FileUpload1.PostedFile.FileName, Server.MapPath("~\\" + "AllClassifiedsImgs\\") + FileUpload1.FileName);
} */ {
File.Copy(FileUpload1.PostedFile.FileName, Server.MapPath("~\\Customer\\" + Session["username"].ToString() + "\\Classified_Images\\") + FileUpload1.FileName, true);
}
if (FileUpload2.FileName != "")
{
File.Copy(FileUpload2.PostedFile.FileName, Server.MapPath("~\\Customer\\" + Session["username"].ToString() + "\\PDF_Files\\") + FileUpload2.FileName, true);
}
}
else if (Session["UserType"].Equals("Shopper"))
{
if (FileUpload1.FileName != "")
/* {
ResizeImage(300, 300, FileUpload1.PostedFile.FileName, Server.MapPath("~\\PWC_Shoppers\\" + Session["username"].ToString() + "\\Classifieds_Images\\") + FileUpload1.FileName);
ResizeImage(300, 300, FileUpload1.PostedFile.FileName, Server.MapPath("~\\" + "AllClassifiedsImgs\\") + FileUpload1.FileName);
} */ {
File.Copy(FileUpload1.PostedFile.FileName, Server.MapPath("~\\PWC_Shoppers\\" + Session["username"].ToString() + "\\Classifieds_Images\\") + FileUpload1.FileName, true);
}
if (FileUpload2.FileName != "")
{
File.Copy(FileUpload2.PostedFile.FileName, Server.MapPath("~\\PWC_Shoppers\\" + Session["username"].ToString() + "\\PDF_Files\\") + FileUpload2.FileName, true);
}
}
}
We commented out the portion of code which called the Resize function and just opted to use the File.Copy line (hopefully you can follow this above) and got around the image uploading issue.
The problem we have now is that when the results are displayed, the thumbnails and images are displayed as small red x's indicative that the filepath/filename is either invalid or the image is not present.
When the developer tests this same application on his computer, the application works as it should. When I copied the exact same folders/files to my own local computer to see if the fact we have our web applications located on the F drive (not the C drive) was the reason however I get the same problems with the display of the images.
I suspect it is a configuration issue or a setting held in the ASPX/ASPX.CS files where it is looking for files or directories or paths which are present on the development environment but not on the server but this is only a guess.
I am late in getting this application released for general use and as a result losing a lot of credibility rapidly. If anyone can help us to solve this issue, I would be eternally grateful.
Please ask any questions you wish as I may not have explained the problem clearly enough.
Kind regards
Lesley
