hello,
i am struggling to hold a pair of values in a dropdownlist
i.e CountryID and CountryName i want to take CountryID when selectedIndexChanged Event raises...
I had done the same thing in desktop app. by overriding .Value() and .ToString Method..
I dont want to write Multiple queries at every time because it is an overhead in web apps.

let me explain...........
public object Value;
public object Value1;
public string Description;
public ValueDescriptionPair(object NewValue, string NewDescription)
{
Value = NewValue;
Description = NewDescription;
}
public ValueDescriptionPair(object NewValue, object newvalue1, string NewDescription)
{
Value = NewValue;
Value1 = newvalue1;
Description = NewDescription;
}
public override string ToString()
{
return Description;
}
----------------------------------------------------------------------
i created one value pair like this......
for that i will get a set of values which overides .Value method
----------------------------------------------------------------------
ddlCountryService.Items.Add(Convert.ToString(new NRIValueDescriptionPair.ValueDescriptionPair(dtr[0],dtr["fld_CountryId"], Convert.ToString(dtr["fld_CountryName"]))));
-----------------------------------------------------------------------
Here i could able to set the values also......
-----------------------------------------------------------------------
obj.CountryId= Convert.ToString(ddlCountryService.SelectedItem.Value);
--------------------------------------------------------------------------
but....
i couldnt able to get the value by .Value method...
it is not overriding... i did this nicely in windows apps.....dont know y its not happenning in web apps
----------------------------------------------------------------------------
hope it will be clear for you now.....

You will get error on this line, if control Name is a server control. This happens because ASP.NET appends user control name with the server side controls to make control id unique. So you need to view source of the page and find out how your control is rendered. Usually it will be like usercontrolname_controlname. Find this name and use that in javascript.

hi,
try to use / instead of \ otherwise use @"\".
\ is a new line character in C# and your code will work only in vb.net.
So it is better to avoid it.

hi
can anybody tell me how to update the database after modifications are done in a dataset.
dotnetSoft

You need to specify update command for the DataAdapter. Then use DataAdapterObject.Update(DataSetObject)

Hi Guru's,
I'm working with datagrid control using template column to bound data on each column, on my grid I used linkButton to redirect to another page, I want to add query string on my postbackurl below is my code:
<asp:LinkButton ID="lnkProd" runat="server" PostBackUrl='xx.aspx.com?pID=<%#databinder.eval(container.dataitem,"productID")%>'>Products</asp:LinkButton></ItemTemplate>
but when I click the links it returned with %3C%#databinder.eval(container.dataitem,%22productID%22)%%3E
Please advice.
Thanks

What is "xx.aspx.com" ?
try with this
PostBackUrl="xx.aspx?pID=<%# DataBinder.Eval(Container.DataItem,"productID")%>"

I rewrite it to
PostBackUrl='xx.aspx?pID=<%# DataBinder.Eval(Container.DataItem,"productID")%>'
But still no luck.

Try replacing ' to ".
Are you trying to do something when LinkButton is clicked ? Is yes you can handle this using ItemCommand event, instead of passing querystring on postback.
|
|
|
|
|
Yes that's what I wanted to do, passing query sting upon clicking on link button, I was under the impression that placing it on Postbackurl will do shorted job  I might look on HyperLinkColumn instead.
Thanks,
I'll still figure it out.
