how to asp.net update panel use in Tree view and grid view


stored procedure is not getting invoked on update command of grid view

  

Hello everybody!

In my project I am using a grid view to display data from multiple tables and I want to update that data on clicking edit button.

For selecting data I am using custom select statement, but for updating I have created a stored procedure which should update two different tables.

 

But when I click on update , it's not executing the stored procedure.

 

here is the code snippet of sqldatasource:-

<asp:SqlDataSource ID="SqlDataSource1" runat="server"  UpdateCommand="editEmployeeInfo" UpdateCommandType="StoredProcedure">

                <UpdateParameters>

                    <asp:Parameter Name="empId" Type="Int32" />

                    <asp:Parameter Name="name" Type="String" />

                    <asp:Parameter Name="address1" Type="String" />

                    <asp:Parameter Name="address2" Type="String" />

                    <asp:Parameter Name="telNo" Type="String" />

ASP.NET Grid View Paging and GridDataRowBound Problem -

  

Hi,

I have a problem displaying data in a Grid View control when I set a row to visible = false when a certain condition is true.

For example, if a DataRowData value has a condition set to true (custom in table) I set the visible property to false, so the data row will not be visible at run time.

The problem is that I'm using paging (10 rows per page) and if 8 of those rows fall into the true condition that won't show the row, that grid view page will only show two rows of data in page 1. The worst scenario is that if I go to page 2 of the grid view and all the rows (10) fall into the true condition, that grid view page will not show any data at all.

How can I show 10 rows of data at all times in a gridview? In other words, I would like to just show the visible rows at all times.

Any help will be greatly appreciated.

Eduardo.


Change grid view from table to other HTML layout

  

Hi,

You'll have to excuse my ignorance, I'm coming at this from a front-end perspective, and don't really know how to deal with data views in ASP.NET.

Basically, I'm trying to change the layout of some repeated data from a straight table, to something more design-heavy.  It's the same data, just re-organised slightly.  The current ASP.NET code looks like this:

		<table>
			<tr>
				<td>
                    <asp:GridView ID="GVMoments" runat="server" AllowPaging="True" AllowSorting="True"
                        AutoGenerateColumns="False" PageSize="20" RowHeaderColumn="FirstName"
                        SkinID="GroupSkin" DataKeyNames="moment_id" 
                        DataSourceID="SqlDataEditMoments">
                        <PagerSettings Mode="NumericFirstLast" PageButtonCount="20" Position="TopAndBottom" />
                        <RowStyle />
                            <Columns>
                                <asp:BoundField DataField="moment_id" HeaderText="moment_id" ReadOnly="True" SortExpression="moment_id"
                                    Visible="False" In

SSRS Subscription Management: Restart, Stop, View Status, update properties, etc

  
As SSRS admins, there are times when a user comes to us and ask: I didn't get my reported emailed to me today?or worst, a report subscription going to multiple people doesn't run and now you have lots of people missing their subscription - (suppose server crashed, or something happened).One idea of course would be to have the subscription owner re-schedule it to run now, or create a new -- but - i'm thinking - we should create a subscription adminstration tool.a .net app that queries the ssrs web service, gets a list of subscriptions in the ssrs system (or perhaps by folder) and then is able to 'restart a subscription', "stop a running one", 'view all subscription status, schedule, owner, etc' if I wanted to d this - what is the web service that I could use this for?and most importanly - has anybody dont anything like this that they can share?this is for ssrs 2005 & and I'm hoping 2008 can be called through the same .net app tool
