i have acheived this one but now it has to be more advanced.
how do i put checkbox list inside the nested repeater. the values of the listitem of checkboxlist should be coming form database. and also i need to make sure that user only checks only one checkbox item from checkboxlist. is there any quick tips for acheiving this. i know how to display information in nested datagrid such as.
Parent
child
child
child
but this time child should be actually a dynamic checkboxlist and based on which checkboxitem user select i need to get both parent id and child ID.
i am just looking for code hint to follow up.
any reference will be great at the moment. or a quick code hint.
thanks in forward.

If you only allow the use to select one item, you may use the RadioButtonList control instead. You can use a datasource control to feed to the RadioButtonList, or programmatically bind data to the control using the DataSource property and DataBind method. You can read more about how to use this control in MSDN.

You may want to declare this object as RepeaterItem instead of the DataListItem.

Hi Its working fine.
but how will i let user only select one checkboxItem within checkboxlist within a repeater.
I know radiobuttonlist will be a good option but again. once the user selects a radiobuttonitem within a repeater they cant actually uncheck it.
please help.

You'll have many ways to check if the user select one or more items:
+ Use the server side code to count the number of the selected checkboxes in the Items collection.
+ Use javascript to validate if the user chooses more than 2 items, you can use a custom validator in this case.
+ Simply persist the current number of the selected checkboxes in a hidden textbox using javascript, and use the CompareValidator to validate the textbox.
+ Keep using the radiobuttonlist, but may consider adding another checkbox and place it right at the beggining of the category name to give the user an option to not choose any item.
It's weird when getting voted down with all 1s

Try doing a search on this site or elsewhere. Threading is a common knowledge area, you should find plenty of examples. Be warned though, you may actually have to do some reserch, thinking and work on your own.

Hi
In asp.net 1.1 datagrid, i have one template column in that i have link. for that link i am passing command arguments like this
CommandArgument='<%# DataBinder.Eval(Container.DataItem, "id1")%>'
I want to pass multiple values(id1, id2) through command argument. how to pass.
can anyone tell syntax for this
awaiting for reply

I think you have to do a delimited string and parse it out in the event handler. IE:
<br />
CommandArgument='<%# DataBinder.Eval(Container.DataItem, "id1") + "|" + DataBinder.Eval(Container.DataItem, "id2")%>'<br />

Hi Developers
I have performed two way sorting on Datagrid and its working very smoothly(When we first click on header of any column, grid wil b sorted in Acsending Order and when we clcik second time on column header, grid will be sorted in descending order).
Now what I need is that there should be two Arrows Up/Down with each header of Datagrid, Now if we click on Down Arrow the Grid should be sort in Descending Order and When we click on Up Arrow datagrid should be sorted in Ascending Order.
Thanks in advance
Lets work it Out.........!

Hi you can use Headertemplate to add ImageButton with default ImageUrl=Uparrow.
then on Item command you do sorting functon also add the Current- sort critria in viewstate
Then OnItemDataBound event find sorting ImageButton in ListItemType.Header and bases on the Current- sort critria in viewstate change the imageUrl property of ImageButton

Thanks for your reply BUT this all I have done, I need to have two Arrow Buttons with each Column Header and when user click on Up Arrow grid should be sorted in Ascending order and vice versa. I hope its clear now...

Hi friends,
I am told to convert all the response which is coming from server which is in aspx format to html format and then display. the purpose of doing like this is to increase the browsing speed. All the link in the web page is linked to their respective .html files. Can anyone tell me how to do this.
Thanks in advance

When you run as aspx page, what it returns to the browser is just html (as it has to be). The only thing that you would really be changing would be the page extension...
Why?

If you want to speed up the site there are other steps you can take. Try reading "Speed Up Your Site" by these guys: http://www.websiteoptimization.com/speed/. This book is really good even though it is a couple years old. It's worth the read.
In .net you can disable viewstates if your are not using them and try to keep your control IDs shorter. The less characters that are sent to the client the faster the site will be.
Although, if your .aspx pages are NOT "doing" anything then static HTML pages would be faster as it won't have to process any code server side.

i am working on web application in which we are using Outproc session mgt.
As we manage session using Outproc there are two ways
1) Sql Server
2) State Server
in above we are using State session mgt.
In this case i want to know if we use Application variable then where actually this variable store on Web Server OR State Server.
Please tell me ... our further development depend on this ....
Thanx in Advance

Well Session object are different than application object so in any case application object will not be there on IIS reset or application stop only the session variables will remain

Hi all I am using following code to bind data with dropdown list
<asp:DropDownList ID="ddPCBackSide" runat="server" Width="150px" DataSourceID="PCBackSideSourceProductFields"
DataTextField="field_defaultvalue" DataValueField="field_defaultvalue">
</asp:DropDownList>
<asp:SqlDataSource ID="PCBackSideSourceProductFields" runat="server" ConnectionString="<%$ ConnectionStrings:sConnectionString %>"
SelectCommand="SELECT field_defaultvalue FROM cp_productfields WHERE field_product_id='Convert.ToInt32(Session["ProductId"])', field_type='DropDownList', field_ID='ddPCBackSide'"
ProviderName="<%$ ConnectionStrings:sConnectionString.ProviderName %>"></asp:SqlDataSource>
I am getting following error during compilation
Error 1 Type 'System.Web.UI.WebControls.SqlDataSource' does not have a public property named 'field_defaultvalue'.
Is there anything wrong in the syntax? Pls let me know.

Try changing the double quotes to single quotes. I haven't looked closely at this but first guess is that is causing the problem.
|
|
|
|

SQL query parameters are in single quote.
