Is this event raised (and the value of the variable defined) when you select the child nodes? Also, what value are you using for the child nodes?

Hi! yes it is raised. sending you the full source which i didnt added earlier.
Delegate Sub TreeNodeSelectedIndexChanged(ByVal Sender As Object, ByVal e As System.EventArgs)
Public Event TreeNodeChanged As TreeNodeSelectedIndexChanged
Public Sub SubscribeTreeNodeChanged(ByVal Del As TreeNodeSelectedIndexChanged)
AddHandler TreeNodeChanged, Del
End Sub
Public Sub UnSubscribeTreeNodeChanged(ByVal Del As TreeNodeSelectedIndexChanged)
RemoveHandler TreeNodeChanged, Del
End Sub
---
Protected Sub tvProperty_SelectedNodeChanged(ByVal sender As Object, ByVal e As EventArgs) Handles tvProperty.SelectedNodeChanged
Me.LocationId = tvProperty.SelectedNode.Value
If dgBuildingComponent.SelectedIndex <> -1 Then
Dim KeyID As Integer = CType(dgBuildingComponent.DataKeys(dgBuildingComponent.SelectedIndex), Integer)
Me.BuildingComponentId = KeyID
Else
Me.BuildingComponentId = 0
End If
bindBuildingComponent()
RaiseEvent TreeNodeChanged(sender, e)
End Sub
thanks

CType(gvProperty.Rows(0).FindControl("txtPV"), TextBox) using this iam to get the textbox and also i write text iam getting the text but how i can change the forecolor to blue of that text box in the grid view
|
|
|
|

Does this code not work for you?
txt = CType(gvProperty.Rows(0).FindControl("txtPV"), TextBox)<br />
txt.ForeColor = Colors.Red
then, you can define the CSS class and set it to Textbox control..

Hello Everyone,
I am new to code project and i have a small scenario : i created a small web form for student details. in that, i placed a "dropdown listbox and a text box".
in dropdownbox(ddb), i added 3 items i.e., marks of a student in paper1,paper2,paper3 respectively.
now, i want to select paper1 from the "ddb" and enter the marks in the text-box.
next,i want to select paper2 from the "ddb" and enter the marks in the same text-box.
likewise for the paper3.
and, when i click a button, i would like to see the total.
below is the sample code i used. can anyone please suggest me how to implement this.
Also, please let me know if this is completely stupid thought.
private void Page-Load(....)
{
if(DropDownList1.SelectedIndex==0)
{
MsgBox1.alert("p1");
}
}
private void DropDownList1_SelectedIndexChanged(object sender, System.EventArgs e)
{
if(DropDownList1.SelectedIndex==1)
{
MsgBox1.alert("p2");
}
if(DropDownList1.SelectedIndex==2)
{
MsgBox1.alert("p3");
DropDownList1.SelectedIndex=0;
}
}

This is obviously test code, but either way, remember this won't work in the real world

Page_Load is a strange place to do this. You should have a submit button and handle it's event.
You've written some very simple test code. If you move beyond that and try to write code that does what you want, you should find soon enough the limitations of hte approach ( for example, if I change my drop list, should the existing value for that selected test be shown right away ? )

By setting the visible property on both controls, and putting them in one column, which is also dynamically named.

Use the GridView.RowDataBound Event and for each new generated row check the seats value (e.Rows.Cells[0].Text) and change the checkbox visibility accordingly. e.Rows.Cells[1].FindControl(checkbox)....

How can I create a browse button (option) that will allow me to browse and get the path where later I am going to save files to ? I need a path not the file name like control input file does. Thank you very much !

Well, you're not going to save files to the local file system, so how would this be useful ?

You mean, input type="File" ?? It's already there. Why do you want to create new?
bircut wrote: later I am going to save files to ?
I'm not sure what you meant. If you are using file input, you can browse the file and upload it to Server.
bircut wrote: I need a path not the file name
As Microsoft says here[^], it's not possible.

Simply, I just want to create a folder browser dialog in asp.net.
Well, let me explain it. A customer order a list of picture to be printed. I want to use something like folder browser dialog to chose a folder and then search if these picture exist in this folder. Then I'll copy all these picture into a new folder (called Printed_Picture). Picture in Printed_Picture folder will be printed.
control is used to choose a file not a folder.

Your boss is an idiot. You can't do that. Well, if you write a browser plug in, you might, but using ASP.NET you simply cannot.
Why would you want a web app that moves files about on the client PC ?

They are printed by a service, or the browser is being used to do something entirely client side, and IE is just being used to print local pictures ? If the image is being printed locally, write a little app they can download and run, what's the point of it running in the browser ?
Either way, HTML/javascript does not allow you to wander about the users file system, and with good reason.

Well, many pictures the capacity is too large and it isn't wise to store them on server. The server only store the thumbnails of these pictures. These pictures is stored in the local desktop in my company. The thumbnail picture and the original picture has the same file name.
The order of a customer always take average 200~300 pictures, it is hard to find one by one in a folder. Then my boss need a control in my company website to search the list of pictures in a chosen folder, then copy them into to Printed_Piture folder. He will choose picture from a folder on his own desktop after checking order, not on a server computer.

Hi all,
I am developing a asp.net c# web application. In which on a specific condition in a code behind page I want to take the client confirmation, How can I achieve this.
eg: If a client has given some input. I will check the input is already exist using the code behind(server side) and then I want to take a confirmation "does he want to overwrite his new input?". I can't do the checking using the client side script.
any help is appreciated.
Thanks in advance.
-Ram.

Your two options then are a postback, or AJAX. you would use client side script if you want to show a confirmation message, there's just no way around that, but you can do a postback or AJAX call to check if you want to show the message.
