Hi,
I am trying to create two sets of drop down lists in a gridview. If i change the index of the first drop down, the values of the corresponding drop down should change. I used event handler for the first drop down, but if i change the index of any one of the drop downs in the first set, all the values of second drop downs are getting changed.

Hi,

Now i understand yr problem. So the initialization of second set of dropdown list u can not stop, while changing of index of first set of drop down list.

So to maintain the state of the second dropdown set. First u need to take the state of all the dropdown list from second set and the again u need to set their state while changing the index of first one.

Now please let me know if you code for that or any query.

Regards

Please have a look at my code:

<asp:GridView ID="grd" runat="server" OnRowDataBound="grd_RowDataBound">   
    
  
<Columns>    
  
  
<asp:TemplateField HeaderText="names">   
  
    
  
  
<ItemTemplate>  
  
    
  
  
<asp:DropDownList ID="name" runat="server" OnSelectedIndexChanged="onSelectChangeddl"></asp:DropDownList>  
  
    
  
</ItemTemplate>  
  
    
  
</asp:TemplateField>  
  
    
  
<asp:TemplateField HeaderText="age">   
  
    
  
<ItemTemplate>  
  
    
  
<asp:DropDownList ID="age" runat="server" AutoPostBack="true">   
  
    
  
</asp:DropDownList>  
  
    
  
  
</ItemTemplate>  
  
    
  
</asp:TemplateField>  
  
</Columns>  
  
    
  
</asp:GridView>

In c# code, i am trying to change the values of the second drop down list based on the value selected in the first. I am doing this as below:

foreach (GridViewRow row in grd.Rows)   
{   
DropDownList ddl1 = (DropDownList)row.FindControl("name");   
DropDownList ddl = (DropDownList)row.FindControl("age");   
  
  
if (ddl.SelectedValue.ToString() != "---Select---")   
  
{   
  
}   
  
else   
    
  
{   
  
ddl.Items.Clear();   
  
}   
  
    
  
SqlCommand SPComm = new SqlCommand("someStoredProcedure", myConn);   
  
SPComm.CommandType = CommandType.StoredProcedure;   
  
SqlParameter param = SPComm.Parameters.Add("@something", SqlDbType.NVarChar, 50);   
  
param.Value = something;   
  
dr = SPComm.ExecuteReader();  //dr is sqlDataReader   
  
int i = 0;   
  
while (dr.Read())   
  
{   
  
ddl.Items.Insert(i, dr.GetString(0));   
  
}   
  
dr.Close();   
  
ddl.Items.Insert(0, "---Select---");   
  
}

In the above code, all the values in the second drop down list are getting duplicated based on the selected index changed event handler of the first drop down list.

Rewrite Url on page post Back

26-Mar-09 2:54

Hi,

I have gone through the your code.

int i = 0;
while (dr.Read())
{
ddl.Items.Insert(i, dr.GetString(0));

}
dr.Close();

In the above code where u increment the I . According to yr code there always i=0. Hence it replicate the value. Why u can not use Datatable or dataset. Howevere using of Collection of object is good choice.

thanks for your response Matthew...
But this is not my solution.
I am explaining my problem a bit elaborately.
My fileupload web application uploads file in say : c:/Directory1.

But the web application where users views the files are in d:/Directory2.

I am listing the uploaded files in a listbox control... which I am being able to do.

Now when a user clicks one item in listbox it just sets the "href" attribute of an hyperlink with "c:/Directory1/" + filename.

But since the files are on another directory, when I click on the hyperlink it does not respond,but on the browser window status bar I can see the path which is assigned to it's href attribute and it's proper.

That shows you have no idea on web applications. Physical path like c:/directory will not work with web applications. It can access only directories which are under it's website space. So you have to keep your upload files in a directory inside your website area.
