Grid view with filter

Posted By:      Posted Date: October 25, 2010    Points: 0   Category :ASP.Net
 

I need to filter a grid view based on Author dropdownlist. I thought there is a way to dynamically add the where clause
in the "onselecting" event of <asp:LinqDataSource>. But if I define the <asp:LinqDataSource as below, "onselecting" does not fire.



    <asp:LinqDataSource ID="dataSrcEco" runat="server"
        ContextTypeName="ECOTracker.DataAccess.ECOTrackerDataContext" EntityTypeName=""
        Select="new (EcoNumber, Description, Priority, Author, DocCoordinator)"
                TableName="Ecos" onselecting="Ecodatasource_Selecting">
        
    </asp:LinqDataSource>


For "onselecting" to fire I also need also add the "whereparameters" section in the linqdatasource as below.

    <asp:LinqDataSource ID="dataSrcEco" runat="server"
        ContextTypeName="ECOTracker.DataAccess.ECOTrackerDataContext" EntityTypeName=""
        Select="new (EcoNumber, D

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

Issue in Infopath 2007 browser form - cascading dropdown using owssvr.dll filter view

  

Referring the below link, I created a cascading dropdown. The parent dropdown has sharepoint list as datasource and the child dropdown has xml datasource that points to owssvr.dll filter view. The cascading drop down works fine in preview but throws error after publishing as admin approved form - "form cannot run the specified query" exception when trying to execute xml datasource i.e., when a value is selected in parent dropdown. The security is 'Full Trust". In the event viewer the error message states "401 unauthorised" for the user a/c. the xml data source is an approved udcx file and in central admin, have enabled cross domain for infopath service. I have tried different solution provided in tech forums but issue still exists. Not sure whether Im missing something. Can someone guide me in fixing this issue?

How to filter view using ListViewXML with group by option?

  
I try to filter my view in list using ListViewXml property. The view has group by section. After implementing a filter for the view data under groups are the same(not filtered), but group rows show quantity of rows for each group  like filter is implemented. So it works well without group by.    XmlDocument document = new XmlDocument();  document.LoadXml(webPart.ListViewXml);  XmlNode queryNode = document.SelectSingleNode(".//Query");  XmlNode whereNode = queryNode.SelectSingleNode(".//Where");    if (whereNode != null)     {        whereNode.InnerXml = query.Query;      }   else       {        queryNode.InnerXml += "<Where>" + query.Query + "</Where>";        }  webPart.ListViewXml = document.InnerXml;
