Normally for inbuild paging we write navigation code Sub Pageing_Routine(ByVal s As Object, ByVal e As DataGridPageChangedEventArgs) SearchGrid.CurrentPageIndex = e.NewPageIndex FillGrid() End Sub But as I am using custom paging I have to implement navigation code for navigation. mycode is... <asp:linkbutton runat="server" cssclass="pageLinks" ="" id="FirstPage" text="[First Page]" oncommand="NavigationLink_Click" commandname="First"> <asp:linkbutton runat="server" cssclass="pageLinks" ="" id="PreviousPage" text="[Previous Page]" oncommand="NavigationLink_Click" commandname="Prev"> <asp:linkbutton runat="server" cssclass="pageLinks" ="" id="NextPage" text="[Next Page]" oncommand="NavigationLink_Click" commandname="Next"> <asp:linkbutton runat="server" cssclass="pageLinks" ="" id="LastPage" text="[Last Page]" oncommand="NavigationLink_Click" commandname="Last"> <asp:datagrid id="SearchGrid" runat="server" autogeneratecolumns="False" onpageindexchanged="Pageing_Routine" allowpaging="True" pagesize="3" allowcustompaging="true" pagerstyle-visible="false"> ..........

It doesn't sound like the sort of thing ideally suited to asp.net. hi Amit Agarrwal30-Jun-06 1:02 Amit Agarrwal 30-Jun-06 1:02  hi want to use mouseover event on image in datalist. can any body help me. the code will be helpfull thanks in advance aavesh Re: hi PlayByTheRules30-Jun-06 1:05 PlayByTheRules 30-Jun-06 1:05  aavesh wrote: hi What a useless subject line.

Nagraj Naik30-Jun-06 0:50 Nagraj Naik 30-Jun-06 0:50  Hi All, I am having problem regarding paging in datagrid. datagrid1.items.count will give me total number of items in grid. But if I am using Paging in grid and I want count total number of items in grid how I can do that. datagrid1.items.count will provide count for current page only and not for total items in all pages in datagrid. I hope you will suggest some solution. Regards, Nagraj -- modified at 6:51 Friday 30th June, 2006 Re: Datagrid item count while paging........ Amit Agarrwal30-Jun-06 1:07 Amit Agarrwal 30-Jun-06 1:07  hi i think u were binding ur Datagrid usng datatable then u can count the number rows in datatable. like let say dim dt as datatable dt.rows.count will give u the number of rows that will show in datagrid. i think it will help full for u or u r using some thing else to bind the grid. thanks aavesh Re: Datagrid item count while paging........ Tirthadip30-Jun-06 1:11 Tirthadip 30-Jun-06 1:11  Hi , I cant actually understand your problem. You are binding your grid with some table data through dataset.Then you can easily count your total no. of records by a single query or one line of code. if you are using dataset then put---- DataTable dt=(DataTable) ds.Table[0];// ds is the DataSet name<br /> int count;<br /> count=dt.Rows.Count(); Alternatively you can use SQL query or stored procedure for counting total records. Even if you add or delete records from datagrid then update the dataset. Why are you using datagrid1.items.count ? May be I cant understand your problem. If I am wrong then write without hesitation.

In which we are calling function which is in 2 layer.this function returns dataset which is then assigned to datagrid in 1 layer.So I can only return dataset from function and not table item count. So my question is how I can get no of items from this returned dataset I hope now I am clear from myside. Thanks, Re: Datagrid item count while paging........ DIMPLE_R30-Jun-06 2:08 DIMPLE_R 30-Jun-06 2:08  Why can't you just derive the number of rows from the returned dataset? something like: ds.Tables(0).Rows.Count Thanks for help.....

I have three DropDowns on my form, 1, 2 & 3, all linked to different ObjectDataSources (ods1 ods2 ods3). DropDown 2 takes the value of DropDown 1 and uses this as a part of it's query parameter, DropDown 3 takes 2's value and uses this as part of it's query parameter. The problem I'm having is that when the page first loads, DropDown2 isn't picking up DropDown 1's value and subsequently displays an empty list. Just using these controls, it doesn't seem to be possible to invoke a PostBack event if DropDown 1 contains a single value as neither TextChanged or SelectedIndex are true when the user selects the item. I'm sure there is a problem with my logic here, so can anyone recommend a good guide on using these controls or offer any advice? Thanks, Martin. Re: ASP.NET 2.0 DropDownList problem DIMPLE_R29-Jun-06 23:12 DIMPLE_R 29-Jun-06 23:12  After populating the first dropdown you can try passing DropDownList1.Items(DropDownList1.SelectedIndex).Value as parameter while filling the second dropdown.. Re: ASP.NET 2.0 DropDownList problem minhpc_bk29-Jun-06 23:33 minhpc_bk 29-Jun-06 23:33  Hi there, In the second ObjectDataSource you can define a ControlParameter as a SelectParameter, and this paramater is pointed at the first dropdownlist control with the PropertyName is the SelectedValue. Also, when the dropdownlist has a single item, IMO you may not need to postback the web page. Re: ASP.NET 2.0 DropDownList problem Amit Agarrwal29-Jun-06 23:42 Amit Agarrwal 29-Jun-06 23:42  hi if i m not wrong u want the value from one drop down to second dropdown and from second doropdown to third drop down.is it ok. if it is like that then then u have to fill the First dropDown at the Time of page load and when user select the second drop down then corresponding to the Value of first dropdown the Second Will fill. for that u have to write the Code in the Event of First Drodown_Selectindex changed. just like For third.. or u have some Other problem then Tell me i hope it will work for u if i m getting right ur question. thanx aavesh server error nishak29-Jun-06 21:44 nishak 29-Jun-06 21:44  :(hi, please anybody reply this server error,while connecting the remote machine through user input ip address of that machine.please reply ASAP Server Error in '/try_web' Application. -------------------------------------------------------------------------------- The requested name is valid and was found in the database, but it does not have the correct associated data being resolved for Description: An unhandled exception occurred during the execution of the current web request.

I would say that IP you are trying to resolve has no appropriate name in DNS database. But I never met exception like this and what I did write is only my opinion.
