Recently we have had some productional issues regarding this command line utility. We ran it and deployed new code which should not have deleted the directory that houses this script and then had to re-run this because we were getting the dreaded "White Screen".
I looked on Google a bit and didnt find anything that answered the question why the directoy might just disappear.
Any ideas?
Thanks,
Cleako

Anyone have an example of using javascript to select a row in a datagrid from a different form. I want the javascript to trigger the selection that then post backs to the server to retrieve the desired result.....
Two Forms:
FormA.aspx - Contains Datagrid, with editable image button, onclick image button renders information on the same form.
FormB.aspx - users open this form from a link within FormA.aspx, once work has been completed and submit button clicked, form is closed which would then trigger the post back method of the image button row click event on FormA.aspx
Any ideas
My eyes hurt!

well actually you can talk to 2 different browser windows.
You could however talk betweeen frames on the same page with the javscript DOM

1 line of code equals many bugs. So don't write any!!

That's not much of an error message... Use the "Ignore HTML tags" option when you post HTML or XML.

b { font-weight: normal; }

system.web
customErrors mode="Off"

Do as the information page says, and you will be able to see the real error message.

Hi,
In my web application (framework 1.1), I have a try-catch block handling errors. When an error occurs it is logged using Logging of EL. Later I also need to navigate to a CustomErrorPage created. Here is how the web.config tag looks like.
<customerrors mode="RemoteOnly" defaultredirect="CustomErrorPage.aspx">
The catch portion looks like this:
catch(Exception ex)
{
#region Log DS Retrieval Error
LogEntry l = new LogEntry();
l.Severity = Severity.Error;
l.Category = "General";
l.Message = String.Format("Encountered error during data retrieval {0}", ex.ToString());
l.Priority = 5;
l.EventId = 13651;
l.Title = "Data Retrieval";
Logger.Write(l);
#endregion
throw ex;
}
When I use the mode as "RemoteOnly" it does not navigate to the error page nor does it give the detailed error page. It just displays error details like error is not handled. When the mode is set to "On" it navigates to the Error Page stipulated.
Any ideas/input on how to incorporate the RemoteOnly mode to display detailed error page on the Webserver and Custom Error Page for the user?
Thanks

Hi everyone,
I added a GridViewRow dynamically that has a textbox. I type something into textbox and do a postback, but the textbox is empty. I'm rebinding the gridview on Page_Load everytime, but I can not see where there issue lies. Can someone take a look at my code and see if they can catch it?

Your code binds data to the grid on every page load. Because of this you are loading a new grid from the database. Anything typed in the grid will be lost when you call the databind() method. What you need to do is save the text entered in the grid and recreate the row. Or just bind the grid once using ifnotpostback() and then bind it again as needed.

But of course, that's all a "high level" overview of things

Hi, Thanks for helping.
I read somewhere that we specifically needed to rebind on every page load so that the dynamically created control can repopulate its viewstate. If I don't do the rebind on page_load, the GridViewRow/Textbox will disappear upon postback.
I tried bind once and rebind after a postback but still the text box is empty.
can you elaborate on this point?
What you need to do is save the text entered in the grid and recreate the row.
Do you mean store text in hidden field or viewstate and manually repopulate the textbox when binding?
Thank You
Jim

One possible solution...
When your page post's back find the row
foreach (GriedViewRow row in gridview.rows)
{
//find your row via some key or id that you add to the row
Textbox txt = (TextBox) row.findcontrol("txtbox1");
viewstate["txtbox1Value"] = txt.text;
}
Now when you go bind the grid again you will have the value
TableCell objTableCell = new TableCell();
objTableCell.ID = "firstCell";
//jTableRow.Cells.Add(objTableCell);
objTableRow.Controls.Add(objTableCell);
TextBox objTB = new TextBox();
//Add the following
objTB.text = viewstate["txtbox1Value"].ToString();

Hi, Thank You again.
I try your suggestion and it works great. We always do grid databind on Page_Load, then onCommand button event, we store the textbox values into the viewstate, after that the sqldatasource automatically rebinds after prerender, this time we repopulate the values from viewstate.
In your oppinon, is it worth the performance hit to create dynamic controls and having to rebind on every page_load and after prerender? We could have simply placed the 2 text boxes outside of the gridview instead of adding it to the grid dynamically. It would have been easier to code but my client insisted on having them inside. What do you recommend?
thanks again,
Jim

actually you shouldn't rebind.
store the table inside your view state
and on page load rebind to the table from viewstate.
theres no need to cache specific row data
private DataTable myTable = new DateTable(...);
pageLoad
if(!PostBack)
myTable = ... get the data from your biz layer ...;
ViewState["MyTable"] = myTable;
set data grid
else
DataGrid.DataSource = ViewState["MyTable"] as DataTable;
rebind
The reason why your changes are not shown is this.
First you create a table which has a unique identifier attached to it.
So you make changes and repost
When you get a new data table you have a different unique identifier which .net will wipe any changes and events tied to that source
You need to rebind every time, but use the table from the ViewState.
Also if you need to add format additional controls use the ItemCreated event to format them.
If you data bind them there, you shouldn't have a need to hack the form and make life difficult

Hi Everyone,
I am working on this project in ASP.NET and I used this code, and I wanted to to output as currency which SHOULD work, but it won't.
<%# DataBinder.Eval(Container.DataItem, "invoicetotal","{0:c}") %>
Is there something that I am doing wrong, no commas or dollar signs show up when I use that for some reason.
Thanks,
The Major Rager

Put this DataFormatString="{0:C}" in the tag but outside of the databinder.

Hi,
Cache is used to store frequently used data and read only data.
Application state is to provide a share point for accessing global, read-only data in an application.
Then What is the difference between Application and Cache.
Which is best in which scenario.
Thanks in advance.
|
|
|
|
|
The difference is that items in the cache will be dropped when the memory resources are better used for something else. If you store too much in the Application object, the server will run out of free memory and start swapping virtual memory to disk, which will make the server very slow.

Hi Everyone,
I am working on a project where I am going to need to make a few charts and graphs using Excel. I do not have the Office tools for Visual Studio and I was wondering what was the best way to do this. The graphs also should not be just an image, but interactive where I can hover or click one of the bars on the bar graph and it should tell me something. If anyone can give me a few ideas I would truly appreciate it.
Thanks

Because you are using chart in an ASP.NET application, I think you may consider using a third party component like Dundas Chart[^].
