This seems incredibly nasty, but I'd say if you need to do this, your best bet is to set what path leads to a particular control, in your resources, and swap resource files as needed. As someone else said, odds are you need to name the classes the same if you want to be able to use them when you swap them out like this. OR a better idea again is to simply define an interface that the controls you're using will have in common and access them via that interface.

In your gridview use the OnSelectedIndexChanging-event
aspx:
OnSelectedIndexChanging="myGridiew_OSIC"
in code behind:
protected void myGridiew_OSIC(Object sender, GridViewSelectEventArgs e)
{
myGridView.SelectedIndex = e.NewSelectedIndex;
String Field1 = myGridView.Rows[e.NewSelectedIndex].Cells[0].Text;
etc...
myGridView.SelectedIndex = -1;
}

There is no inbuilt rich textbox available for ASP.NET. Taking HTML depends on the control you are using.

I'm trying to work with Excel objects in C# for ASP .NET 2.0. I am receiving the following error:
System.Runtime.InteropServices.COMException (0x800A03EC): Exception from HRESULT: 0x800A03EC at Microsoft.Office.Interop.Excel.Sheets.Add(
I am trying to follow the article here but it is in Visual Basic. The .Add function does not include any parameters but in C#, it seems I must pass the 4 parameters. (Object before, object after, count, and object type).
The article for reference is at: Generating Excel Reports in ASP .NET 2.0[^]
Unfortunately, I will not be able to post any code, but does anyone know of any good articles on how to work with excel to generate spreadsheet that is generated from data and then the chart added in C#?
Thanks

Hi,
Can you give little more information? Are you sending the data which is in grid to excel file? If so, I have code which exports to .CSV file from a gridview...
If your question is the same, I can share the code for you.
Thanks...

|

Yes. My problem is the same. If possible, please share the code with me. My email id is abhisek.ch84@gmail.com.

Hi,
I am trying this for couple of days. But could not solve it.
I am calling a stored procedure (it has 3 I/P parameters) with command object and binding to a gridview.
One parameter takes multiple values (ex: 10,20,30) When I debug the application, all the values, its passing correctly.
(When I run the stored procedure in the back end, its giving all the rows)
But after binding to gridview, its displaying only the first value.
For example,
If I pass company as 120 and fund as 10,20,30 and date as 3/31/2008, the stored procedure is taking all the values. But when it displays in the grid it showing only the data of fund 10.
Please help me. how can I get the values in the grid.
Thank for all your help.

hey guys
i have a drop down list in my DetailsView control that when the DetailsView DataBinding event calls i'd like to ptogramitically select a certain item in it
i used this code but it returns an error:
(Object reference not set to an instance of an object.)
protected void DetailsViewEditLink_DataBinding1(object sender, EventArgs e)
{
DropDownList drpEditType = new DropDownList();
drpEditType = (DropDownList)DetailsViewEditLink.FindControl("drpEditType");
drpEditType.SelectedValue = [SomeValue]; //Error happens in here
}
I'd like to know why this error happens
troubling shoot tips were:
1. use the "new" keyword to create an object instance (which i did or didnt i?!)
2. check to determine the object is null before calling the method (what object is null?!)
thank you so much

If FindControl() is not getting the control, it will return a null value.Always check for null before you do something with that object. This is the way to avoid error.

Here no need to use the new keyword. You are assigning the reference here.

oh i see
so can you please tell me how can i find a specific control like a drop down box that i put in one of edit item templates of my DetailsView template fields.
|
|
|
|
|
On the prerender method of the detailsview
Ask for the currentmode
<br />
If Me.dv.CurrentMode = FormViewMode.Edit Then<br />
CType(Me.dv.FindControl("controlid"), DropDownList).Selectedvalue = YourValue<br />
End If<br />

How do you guys handle exceptions in ASP.NET applications? Client-side pop-up tricks? Catch and redirect to a helpful error message page, or default and redirect to a general error page? Change views from a capture view to an error view? The way I think I should be going about this is:
Client-side validation messages etc.
Server side catch specific exceptions only at top level, i.e. in Page code, and redirect to or present task specific error message.
Server side "auto" redirect for all other exceptions.
Pits fall into Chuck Norris.

That's a requirements related question so the answer can be different from company to company as well as application specific. There is no cook book answer to that question.
That said, most server based processes should log things as this makes problem solving much simpler. That's not saying that desktop applications should not log.
ASP.NET has some default message options that you should understand before deciding. In our case we just use those and in conjunction with logging we have found it works just fine for us.

Hi
I am having problems getting set focus to work, I have a page with numerous user controls on it but always need the focus to return to one text box following postback. - This control is also within its own user control.
I have stripped out lots of code to try and track down the error, my current position is as follows.
The main page has one button on it, to force a postback, there is no code within the onclick event. The page has one user control, SwipeCard2
This user control has an update panel on with updatemode set to conditional, a text box (txtswipe) and a label lblError.
This control has the following code which is used to register the javascript to set the focus
Public Sub SetFocusToControl(ByVal page As System.Web.UI.Page, ByVal control As System.Web.UI.Control)
Dim strScript As String = String.Format("document.getElementById('{0}').focus();", control.ClientID)
strScript = String.Format("<script language=""JavaScript"">{0}</script>", strScript)
page.ClientScript.RegisterStartupScript(Me.GetType(), "setFocus", strScript)
End Sub
Protected Sub Page_PreRender(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.PreRender
' CSBSetFocus()
SetFocusToControl(Page, Me.TxtSwipe)
Me.UpdatePanel1.Update()
End Sub
The above code works a treat, if you click anywhere on the page to remove the focus, then click on the button, the cursor is returned to the text box within the user control.
I have now added the following code to the TextChanged event
Me.lblError.Text = "This is not a supervisor account!"
Me.TxtSwipe.Text = String.Empty
Me.UpdatePanel1.Update()
Now the cursor will not appear in the textbox following postback,
Any ideas?
Regards
Tom

If anybody else wants to know the fix put
ScriptManager.GetCurrent(Page).SetFocus(Me.txtScan)
in pre render of the control
