In my webform i
have 4 dropdowns , 5 textboxes and 6 radiobuttons 5 buttons.
if i select 1st ddl then relevant data will be displayed in 2nd ddl.
if i select 2nd ddl then relevant data will be displayed in 3rd ddl.
if i select 3rd ddl then relevant data will be displayed in 4th ddl.
1st ddl,2nd ddl,3rd has autopost back=true;
In this two radio buttons has autopost back=true;
whenever iam selecting one of the radio buttons 3rd ddl is going to the zero index
i.e.. whenever data is sent to server then 3rd ddl is lossing its selected value and then showing the value with zero index.
i already binded the data at the required places.but the problem is not solved.

It's because you're posting back....the simplest way to do this would be to use javascript's document.getElementById method to get hold of the dropdown, and set its value manually...

And where is that? It sounds like the problem is that you are binding the 3rd ddl and wiping out the existing items and selections.

I have the following code:
Protected Sub Page_Load(ByVal sender As Object, _
ByVal e As System.EventArgs) _
Handles Me.Load
Dim strConn As String = MRMFunctions.WebConfigConnString
dsTitles.ConnectionString = strConn
Dim strTitleSQL = "SELECT * FROM tblTitles WHERE [Deleted] = 0;"
dsTitles.SelectCommand = strTitleSQL
cboTitle.DataSourceID = dsTitles.ID.ToString
cboTitle.DataTextField = "Title"
cboTitle.DataValueField = "TitleID"
End Sub
The purpose of this code is to retrieve the connection string from the Web.Config file and place that into a variable called strConn.
Next, I assign the SqlDataSource(dsTitles)control to that connection string.
I retrieve the data I want from the Sql Server Database with the strTitleSQL statement by selecting every field from the tblTitles table where the field named ‘Deleted’ is equal to false. I set the Datasource select command to the strTitleSQL variable.
I am now going to databind the control cboTitle by assigning the DataSourceID equal to the dsTitles datasource ID.
I assign the cboTitle.DataTextField to the Title field from the SQL statement. This is the information that will be placed in the drop down list.
Logically, I should be able to assign the record ID number to the DataVieldValue by assigning the cboTitle.DataValueField to the TitleID field. Instead I am getting the error, “Conversion from string ‘TitleID’ to type Decimal is not valid.”
I understand that it is seeing the string ‘TitleID’ as the string for the DataValueField. What I don’t understand is why is the DataTextField is seeing ‘Title’ as the field name from the SQL statement, but the DataValueField is not seeing ‘TitleID’ as the same?
Thank you,

It seems the error is coming from somewhere else where you cast that string to the decimal type. Is that all your sample code? If so, can you also post the stack error?

You are correct. I was trying to retrieve the value from the cboTitle.DataValueField instead of decTitleID = CDec(cboTitle.SelectedValue)
I get the record ID number this way.
Thank you,

Go to the login form and set the AcceptButton property to be the ID of your Login button. You can also set the CancelButton if your login form has one.

Use a generic list object, adding each new page to it, and then storing it in the session object. You can then iterate down the list seeing all the pages visited to get to the current page.

Use the Javascript history object in the browser.

Hi,
I have written a loop which iterates through all the directories and gives a list of files whose filenames contain a specific search word that has been specified by the user on GUI.
Now I need to display this file list with a hyperlink for each item, so that user can directly click that link and the file associated with that item will open.
How do I do that ?
Pls guide me
Thanks and best regards

How about iterating through the array and creating hyperlinks for each file? One thing to consider is the files are going to be on the server, the user is on a client machine. The list might have drive letters in the path, ie c:\\myshare\\myfile.txt whereas the user would really want to see these as \\server\myshare\myfile.txt.
<br />
<br />
Array<string> mylistofFiles<br />
<br />
<br />
foreach( string myFile in mylistofFiles )<br />
{<br />
HyperLink lnk = new HyperLink();<br />
lnk.Text = "Click to view " + myFile;<br />
lnk.NavigateUrl = myFile;<br />
yourForm.Controls.Add( lnk );<br />
}<br />
This is from memory, and really a 'concept', not a concrete solution. If the file extension is registered on the users system, the correct app will open it for viewing.

Hi,
Thanks for replying. I tried using the above mentioned solution. Worked perfectly fine as far as creating the Hyperlnk is concerned. But the problem here is that when I click on the hyperlink, nothing happens.
What should I do for that.
Thanks a lot for responding quickly.
Best regards

Here, you might use javascript to enable/disable the Next button, you can do that by registering your script with the client side onclick event of the radiobutton.
