how to insert treeview in to a datagrid or gridview.

You can add a Templated field to your GridView. Then edit the templated field and add the TreeView to its ItemTemplate.

by doing this process i am getting treeview for all the itemtemplates.but here i want single treeview for a datagrid.

Would you mind if I ask what exactly you are expecting from this treeview? If you want just one treeview, then you will have to place it outside your GridView. If you want to tie events, then you will have to handle it either through one of GridView’s event handlers or one of the TreeView’s event handler… again, what exactly do you expect from this?
On another note, if you want to illuminate postbacks with your treeview, you can use this third party control:

Hai,
I want to create Xml based Text Report. How can i implement it .Please provide the steps...If you have sample code or alternative solutions Please give me......

One obvious way would be XSLT. That's probably the best way to turn XML into a text report. Just google for XSLT, and you'll find heaps of info.

Isn't there the CLICK EVENT in LsitBox or Grid? Or ais there anyway instead of CLICK EVENT?

What is it you are trying to do? The listbox and gridview have the SelectedIndexChanged event that is fired when an item is selected

I have several boundfields in GridView1, I am allowing user to update without touching the ID field.
foreach (DataColumn dataColumn in ((DataTable)Session["dataTable"]).Columns)
{
BoundField boundField = new BoundField();
boundField.DataField = dataColumn.ToString();
boundField.HeaderText = dataColumn.ToString();
if (boundField.DataField == "ID")
{
boundField.ReadOnly = true;
}
GridView1.Columns.Add(boundField);
}
GridView1.DataBind();
During editing, I am able to see all cell values correctly:
int columnCount = ((DataTable)Session["dataTable"]).Columns.Count;
String[] parameterValues = new String[columnCount];
for (int columnIndex = 0; columnIndex < columnCount; columnIndex++)
{
parameterValues[columnIndex] = GridView1.Rows[e.NewEditIndex].Cells[columnIndex + 1].Text;
}
But when updating, only the cell with the boundField whose ReadOnly = true has the correct value, while other cells have blank.
Help please.

Hello,
I am creating a custom control where I have a button.
Somehow my button click event is not being raised.
I tried to place different codes inside MyButton_Click and nothing runs.
Then I added Context.Response.Redirect("http://www.google.com").
When I click the button postback is done but the page google is not called.
I am on this for days. I looked everywhere in Google and everything seems ok.
Could someone, please, tell me what to do to try to figure what is the problem?
I don't know what else to try.
Thank You,
Miguel
Here is my code:
...
Public Class Contact
Inherits WebControl
Dim MyButton As New WebControls.Button
Private Sub MyButton_Click(ByVal sender As Object, ByVal e As System.EventArgs)
Context.Response.Redirect("http://www.google.com")
End Sub
Private Sub MyButton_Init(ByVal sender As Object, ByVal e As System.EventArgs)
MyButton.ID = Me.ID & "_bSubmit"
MyButton.Text = "Submit"
End Sub
Protected Overrides Sub CreateChildControls()
AddHandler MyButton.Init, AddressOf MyButton_Init
AddHandler MyButton.Click, AddressOf MyButton_Click
MyBase.Controls.Add(MyButton)
MyBase.CreateChildControls()
Me.ChildControlsCreated = True
End Sub
End Class
|
|
|
|
|
SInce you are adding the button dynamically you need to make sure the click event is reattached on page load
Something like this
public void OnLoad(...)
{
MyButton.Click += MyButtonClick
}

Hi there,
You can create a handler for the DayRender event of the control, in the method you can check the value of the e.Day instance and set the IsSelectable property accordingly.

Hello,
I am trying to convert an Asp.Net XML sitemap file in a Google XMl sitemap file using a XSL file using an HttpHandler.
Everything seems well in my code but I am getting an error:
XML Parsing Error: not well-formed
Location: http://localhost:1132/WebSite/Google
Line Number 2, Column 62:<urlset xmlns="http://www.google.com/schemas/sitemap/0.84" />
I tried to display it as Text instead of Text/XML. I don't get the same error. I just get a bunch of squares after the line:
Line Number 2, Column 62:<urlset xmlns="http://www.google.com/schemas/sitemap/0.84" />
Could somebody help me out? I tried everything I could think of for the past 2 days.
I post my entire code in this post.
Thanks,
Miguel

Hello,
I am creating VS2005 web project which includes various custom controls.
One of those controls uses a XSL file.
How can I embed the XSL file in my .dll so I don't need to place it in all my web sites?
Thanks,
Miguel

If your custom controls are in a seperate project you can add the XSL file as an embedded resource. Or you can place it in a resource file in the web project.

Hi Guys,
I'm new in ASP.net. I'm trying to write a web application that has a login. For each login, they will see different function and information. The question is do you guys have any suggestions of what I should use? Can you give me a starting point or an article about this that I can refer to?
Thank you much

Session variable work very well for this. You should be able to find plenty of articles on the use of session variables. It should work something like this.
Login - The user enters there details into a couple of textboxes
Validate - You get the details from the textbox and check them against a database containing all login info.
Set session variables. - You set the session variables up. Eg one called Username to hold the users name, one called usergroup to hold the group the user is in ( to determine permissions)
Forward User - forward the user to the page they should see after login
Then on every page that needs to validate the user, add to the Page load event a script that gets the users group setting from the session variable. Usually the best way to run through permissions would be to use a select statment (vb) or switch statement (c#), which would perform different setups depending on the users group setting. Usually this would be done using the visible attribute of each control required for the user.
I hope that makes sense. I did kind of rush what is quite a complex subject.
One other things. If you want to save time and coding when validating a user into each page, place the code that performs this in a masterpage. Obviously this will only work for global requirements, but in a scenario with a menu this is perfect.

Why not use the Login Control and/or Forms Authentication that is built in? Easier than trying to re-invent the wheel.

Hi,
I am a novice to the Ajax world. I am currently working on ASP.net 1.1 with C#.
I would like to add Ajax features to my app.
There seems to be a lot of options to pick from. I am not clear what works with ASP.Net 1.1 version too.
My main objectives are:
1. Has to work with ASP.NET 1.1
2. I dont want to write the generic portion of Javascript.
[I don't mind writing code for my own functionality. But I would like to have pre-built generic function(with documentation).]
3. I want a mature framework that has been tested well on other apps with common issues resolved.
4. Cross-Browser support for commonly used browsers .(IE, Firefox , Opera, Safari) .
5. I am seeing a lot Ajax container implementation.
What is the advantage/limilation of using an Ajax container vs an Ajax Framework.
Can someone help me to decide what framework/approach I should take.
Many thanks.

Are you sure you can use Atlas with version 1.1. I was under the impression it would only work with version 2.0???????

Hey,
Having some issues catching events from a Datalist. The main reason for this is due to the Datalist being embedded inside another datalist. I can grab all the events from the Outer Datalist no problems(one of which hides and shows the inner data list). I have a save button and some checkboxes in the inner datalist and need to catch all of their relvant events.
Any Ideas? I dont even know where to start on this?
Here is the page code

You have to manipulate each control placed inside another List by using its ID.
for example:
You can reference the embedded Save Button instance and attach Click event by
Button saveButton=CType(DataList1.Items(0).FindControl("saveButton"),Button)
AddHandler saveButton.Click, AddressOf SaveButton_Click

Hi.
Last week I posted a question regarding reading Excel file and loading it into the DataGrid.
I didn't get any useful response back so please forgive me for posting this second time.
I'm sure someone had the same problem I have.
I have 3 columns in Excel. One of the columns (User Id) has text data (like: User 1) or a number data (like: 12345). My code works and doesn't throw any error but for some reason it only extracts text data. The numbers are missing and I'm not sure why. I've tried to foramt that columnt to TEXT only but it doesn't help. Just to be sure I looped through DataSet to make sure the values are there and of course they weren't.
Here's the code that reads Excel and loads data into DataGrid. Please help.
Thank you.
Try<br />
'Create DataSet and DataAdapter<br />
ds = New System.Data.DataSet<br />
da = New System.Data.OleDb.OleDbDataAdapter<br />
<br />
'Establish connection<br />
con = New System.Data.OleDb.OleDbConnection( _<br />
"provider=Microsoft.Jet.OLEDB.4.0; " & _<br />
"data source=" & Session("ExcelFilePath").ToString() & "; " & _<br />
"Extended Properties=Excel 8.0")<br />
<br />
'Create command<br />
cmdSelectExcel = New System.Data.OleDb.OleDbCommand("SELECT * FROM [Sheet1$] ORDER BY Company", con)<br />
<br />
'Open connection<br />
con.Open()<br />
<br />
'Exectue command through adapter<br />
da.SelectCommand = cmdSelectExcel<br />
da.Fill(ds, "[Sheet1$]")<br />
<br />
'Assign DataSourse of the DataGrid and bind it<br />
dg.DataSource = ds.Tables(0).DefaultView<br />
dg.DataBind()<br />
<br />
'Close Connection<br />
con.Close()<br />
Catch ex As Exception<br />
'Display error message<br />
lblError.Text = "Error: " & ex.ToString()<br />
lblError.Visible = True<br />
End Try
