Forms Data Controls :: Gridview 'EmptyDataText' Text Not Showing When No Records Returned
May 5, 2010
using asp.net/vb.net 2005
In the aspx page I have the EmptyDataText property set
[Code]....
However when no records are not returned I am not seeing the text "No Results Returned" I am populating the gridview using a SqlDataSource. I am not sure why this is happening but thinking about setting the value programmatically, does this make sense and if yes which gridview event should I do this? has anyone else experienced something like this before?
Does somebody have a clue about my following issue? I have a gridview with it's datasourceid set to "ods". I have two objectdatasources. One is called "ods" which contains a list with all contracts. The second objectdatasource is called "odsAuthorized" which contains a list with all authorized contracts.
Now i have two linkbuttons "Show All " | "Show Authorized" whith an onClick event where i set the datasourceid of the grid.
When i click the "show authorized" i see a list of all contracts which are authorized. Now when i click on "Show all" is see a list with all contracts. So the onClick events work fine, however. When i change the status in the database so i have 0 authorized contracts, and click on the "Show Authorized" i get to see a label which says "Sorry no records have been found" because i have set the EmptyDataText property on the gridview. Now when i click on Show All, the onclick event for the Show All button never gets fired. I do see that a postback occurres. But i don't come into the event. Does anybody have a logica for this?
I am working on a site using .aspx controls. Currently I am working on a search feature which searches my database of records and produces all applicable results to the search. Everything works as planned. I have recently added the EmptyDataText line to produce a specific output anytime no results are found in the database. However, I would like to be able to alter/change the appearance of the EmptyDataText output and cannot figure out how to do so. For example, if no results are returned from the search, I would like the EmptyDataText to produce an output of something along the lines of "Your search has produced zero results.
double check your spelling and try your search again." I would like to change the font color, font size, and possibly the thin box which is automatically produced around this output. Is any of this possible? If not, is there another way to produce the desired results? Ultimately, I would actually like to have the results actually use the terms which were input to the search within the EmptyDataText results when no search results are found within my database. For example, if "widget" was used as a search term and "widget" was not found within my database then i would like the results page to state something along the lines of: "Your search for 'widgets' did not return any results. check the spelling and try your search again." Does anyone know how to do any of these things using ASP.Net?
I can't seem to get either EmptyDataTemplate or EmptyDataText of a GridView to work. I'm fetching the GridView contents in de codebehind and attaching them with using DataBind(). I've tried having them as null and as an empty List, and in both cases the text I put intoEmptyDataTemplate or EmptyDataText is not displayed. What am I doing wrong?
I have a DropDownList when selected, brings up Detail Info in GridView1. That GridView has a LinkButton when selected brings up the final Detail Info, in GridView2. need to have the GridView2 clear out and display as when it is "EmptyDataText", when the DropDownList is changed.
dlRSS.DataSource = GetRSSFeed("http://www.foodsafetynews.com/headlines.xml") dlRSS.DataBind() Function GetRSSFeed(ByVal strURL As String) As DataTable 'Get the XML data Dim reader As XmlTextReader = New XmlTextReader(strURL) 'return a new DataSet Dim ds As DataSet = New DataSet() ds.ReadXml(reader) Return ds.Tables(2) End Function <asp:DataList ID="dlRSS" runat="server" Width="100%" > <ItemTemplate> <strong><p><div><asp:HyperLink ID="TitleLink" runat="server" Text='<%# Eval("title") %>' Target="_blank" NavigateUrl='<%# Eval("link") %>'/></div></p></strong> <strong><p> <div><asp:Label ID="SubtitleLabel" runat="server" Text='<%# Eval("description") %>' /></div></p></strong> </ItemTemplate> </asp:DataList>
But is returning all rows in RSS Feed I would only like top 5 or so
I just hit the same problem as described here: [URL] - GridView paging with ObjectDataSource. I see the column headers but no data, and I know for a fact my method returns a DataTable with data in it.
I want a tutorial or an example showing on how to upload details or records on text file to Gridview. The way it is with Excel file where we upload to Griview.
how to use a multiline text box that i could copy data into. Lets say addresses one on each line and then click submit and have it display those records in the database (SQL) in a gridview?
I want to show my database records in circle. If i use grid view or data grid or datalist then records will show in table structure. I want to show dynamic records in circle not as like forum view.
I have a standard gridview, with the standard paging and sorting interface enabled.The application holds appointments for three organisational units, with a maximum of 3000 appointment records being returned across all three units. The appointment records are quite small.
The choice I am faced with is to:
1. Have an Org Unit dropdown which returns to the datasource on change of selection and at inital databind, and returns appointment records for one org unit at a time i.e. approx 1000 records.
2. Have the objectdatasource return all 3000 appointment records for all org units at initial databind, and filter the objectdatasource by org unit on change of selection, thereby saving a trip to the datasource.
I guess the question boils down to identifying the point at which querying the datasource by org unit is more efficient than filtering the records returned by org unit.
Is 3000 records a lot for a gridview to be paging and sorting etc.
i am using asp.net gridview control and i have Eight thousand records, than i am using paging techniquies on each page 10 records displayed now i want to display message YOU ARE VIEWING RECORD FROM 0 to 10 OUT OF 8000
I have a form where i want to view all columns from a table.I have a textbox and differeent radio button having values of each column.On click of button.I want to view all the columns as per selected row/rows from value given
I would like to be able to set the EmptyDataText property using code-behind. I have created a custom GridView control called PagingGridView. Here is the definition:
public class PagingGridView : GridView { }
In my ASPX page, I would created a new GridView definition by doing this:
When I databind the control, I would like my custom control to automatically detect an empty data source and build a table with all the header columns and a row containing the empty data text. The rendered code for the empty data source would be like:
<table> <tr> <td>Col1</td><td>Col2</td> </tr> <tr> <td colspan="2">No Records to display</td> </tr> </table>
My initial thought was to override the EmptyDataText property but I could not get that to work.
I've got a dropdownlist and a Gridview Based on the choice from the dropdownlist (which has a '--Select--' as the first item), the gridview is populated. If nothing is in the database when queried, I have a message for the emptydatatext property of the gridview. However, it comes up when the page first loads, since it's based on the ddl. How can I make it so that, when the page loads for the first time, the emptydatatext property is ignored?
I have a gridview and would like to display one of 5 icons depending on the value returned from the database for that row (simply just A, B, C, D or E). Which event in my datagrid should I be looking at to check what value I'm getting? I presume once I can check a value I can simply set an image source using if statements?
Is it possible to bind data to specfic columns in Gridview?
I mean, if I send a query to my database and it returns 1 column, then bind that column to the first column in the gridview, then send another query and bind the resulting column from that query to the second column without erasing the data of the first column etc etc.
I am working on creating a stored procedure that will output a pivot table. In the pivot table will be either the string NULL or a number. How can I reformat this in ASP.NET so the NULL value becomes a blank cell in the gridview and the number (whatever it is) becomes an 'X' ?
I need to format this date time into the format Day/Month/Year on the same template field.
I am avoiding doing this under SQL server because that will mean changing my data type in my dataset to string instead of data time which i do not want.
I FORGOT TO ADD A DATASOURCE TO THE GRIDVIEW. GRIDVIEW NOW SHOWS. ****When I run my web page my gridview is not showing up. Don't know why. The page is nothing more than an image at top followed by a gridview below.
