You can use arraylist, hashtable, ordereddictionary, queue, stack etc. Choice depends on your usage.

Hi all,
I am using C#.NET 2005. SQL Server 2005. Is that possible to have a multiple datavaluefield in dropdownlist? Normally i am using ddl.selectedValue to get value for that selected item. So, can i get 2 or more value under a item?
any suggestions are welcome
thanks in advance.

No. Actually there must be only one Value for each Dropdown option.
Also the DataValueField will be unique. If you want to create such thing, you need to use your own dropdownlist.
|
|
|
|
|
you can do this by adding a custom data field to the data source having value as concatenation of the two or more fields that you wanna use as DataValueField.
Then again process/manipulate this value while retrieving the SelectedValue of the dropdown list.

Hi,
Thanks for both of your kindly help. I have found a solution. I am using concatenation in query and put in the DataValueField.Then retrive it by ddl.selectedValue.split() to get the value in string array.
Here is the example:
Query = Select (fieldA + ',' + fieldB) as Result From Table1
Set DataValueField to Result.
Then, set String[] aResult = ddl.selectedValue.split(',')
Finally get value from aResult[i].
Thank you

for that u have to handle RowDataBound and SelectedIndexChanged Events. Below is the code
protected void gvItems_SelectedIndexChanged(object sender, EventArgs e)
{
Response.Redirect("ToPage.aspx?SelectedItemId=" + gvItems.SelectedDataKey.Value)
}
protected void gvItems_RowDataBound(object sender, GridViewRowEventArgs e)
{
if(e.Row.RowType==DataControlRowType.DataRow)
{
e.Row.Attributes.Add("onclick", ClientScript.GetPostBackEventReference(this.gvItems, "Select$" + e.Row.RowIndex));
}
}
Now at ToPage.aspx u have the Id of the Selected Item so you can display the data related to that item as you want to display.

Waste of time doing a Response.Redirect from a postback event, just use a Hyperlink column.
only two letters away from being an asset

Please look at all of the requirements. The image clearly shows and says the OP want to click on a LINK
only two letters away from being an asset
|
|
|
|

yes, it's my mistake. I just followed the words that were written in the main post and ignored the one in the image.
|
|
|
|
|
Ok, it works, because when I click the link, it has this value
"http://localhost:3849/progetto/visualizza.aspx?IDModello=24," but now to see the data, including other photos in the DataList , how should I proceed?
|
|
|
|
|
|
"IDModello" is a sql int variable.
When I click on the gridview (see the image I posted),I want to appear a DataList with only the data that I want to ... not all!
|
|
|
|
|
Use a Hyperlink column or a Template column to place the link in the grid
only two letters away from being an asset
|
|
|
|
|
<ItemTemplate>
<asp:LinkButton ID ="LinkButtonemp" CausesValidation="false" Text='<%# Eval("EmployeeName") %>' runat="server" CommandArgument='<% #Eval("EmployeeID")%>' CommandName="View" CssClass="gridlnk"/>
</ItemTemplate>
Append the name/ID to the querystring and redirect it to another page say InfoPage.aspx.In info page Request the query String .With the Help of Query String Get the Data in the InfoPage.aspx.

Hello All,
In my ASP.Net application, i am showing a confirmation box using javascript whenever user intends to delete something.
I have written this code in aspx file
function confirmation()
{
if(confirm("Are you sure?")==true)
return true;
else
return false;
}
Then on Page_Load of my codebehind, i am using this:
btnDelete.Attributes.Add("onclick", "return confirmation();")
It is working fine, if user click ok record is deleting and vice versa.
But when i am trying to write same thing for my GridView delete link its not working, i am writting this:
GridView1.Attributes.Add("OnRowDeleting", "return confirmation();");
Can anybody help me? why its not working for GridView_RowDeleting method?
Thanks,
Nagendra.
