Forms Data Controls :: Using Gridview - Alter EmptyDataText Results
Jul 10, 2010
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?

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 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?
EDIT (Code snippet) This is my GridView:
<asp:GridView ID="grid" runat="server" EmptyDataText="EMPTY"></asp:GridView>
And I've tried these two for binding the data:
grid.DataSource = new List<object>();grid.DataBind();grid.DataSource = null;grid.DataBind();

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.

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?

I've already searched to no avail for an answer to this question:is it possible to dynamically alter the page size in a paged gridview based on data in a particular column?In other words,let's say I get data from a table that lists students enrolled in a particular course.If there are 10 students in Course "A," then I want page 1 in my gridview to show 10 records.
If there are 15 students in Course "B," then I want page 2 in my gridview to show those 15 records,and so on.I imagine that this could probably be done with a master-detail kind of set up,but let's say for the sake of argument that I don't want to go that route.

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:
<cc:PagingGridView id="MyGrid" runat="server" ><cc:/PagingGridView>
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'm not sure how to search for what I'm seeking, so I'm hoping to be pointed in the right direction.
I have 4 gridviews that contain the same 3 rows of data. For each gridview, I need to create a seperate gridview that will do some calculated values on the parent gridview like A3-A1, to put it in spreadsheet terms.
And at the very bottom I will have a total gridview control that will sum up each row from the parent gridviews. And under that gridview a final gridview to perform the A3-A1 calculation.

I have a gridview on a page with search boxes at the top.
The wildcard for these is % so in every serach box I set the default to be % so that when the page loads all records are shown and then they can be narrowed down by what you search for but when the page opens the gridview does not show all results.
Here is my code:
<%@ Page language="C#" masterpagefile="MainContent.master" title="Electrical Storage" EnableEventValidation="false" %>
<asp:Content id="Content1" runat="server" contentplaceholderid="Content">
<div id="Rightside">
<h2>Search Electrical Storage

My sql statement is not functioning correctly. The gridview does post the items correctly but the results are not correct. Can someone assist me with the sql statement where I'm going wrong with it?
I only have one being reffer to the code because I was testing to see it work. Eventually, the search will be base on multi select and the selected items are going to the stored procedure to search for the proper records.
The following is the site code and sql code. -carlos

I have a datalist in my site which displays html tables filled with data from a sqldatasource. I need to be able to remove one column from the table and put it back again (including the tags in my table which pull the data from the datasource e.g. <%# DataBinder.Eval(Container.DataItem,"Forecast1") %>) I need to be able to do this because I have options to change the sqldatasource query, and I need to alter the table to keep it compatible with the query. What is the best way to do this?

I am using visual studio 2010, asp.net 4.0 (c#)
My problem is:
How do I display results from my database on a gridview based on the selected row of another gridview.
For example, I have a e-shop web app and I have a product categories table in my database displaying the data on a gridview.
I want to be able to click on the select button on each row and use that event to populate another gridview based on the ID of the product category that is clicked. E.g say the 'CDs' row is clicked, another gridview shows all the different CDs.
As a result, I need the select(sql) statement for the second table to be dynamic based on what the user clicks.
Has anyone done anything like this before?

I am trying to figure out how to bind my link results to a datasource so it can manage/update/edit/insert/delete without me having to do manual coding for all of it. Is this possible?What am I doing?I have used the LINQ to Active Directory to access our AD accounts. I need to make this a webpage frontend of basic search and managing functionality. I have it searching now and adding the results to a gridview but edit is not working now. I was looking online and I saw something about being able to bind linq results to a datasource and then using the datasource to manage all the information for me. Resources I am using:

I have a gridview that I want to bind the results of a query to it once a user selects a value from a drop down list.
The query selects the same row from the same table but selects different fields based on the drop down list value selected
I get to the query selection but it does not refresh that page with the populated gridview.
Here's the code behind code
protected void ddlQuantity_SelectedIndexChanged(object sender, EventArgs e)
{
SqlConnection connection = null;
connection = new SqlConnection(ConfigurationManager.ConnectionStrings["PSI_DB_1ConnectionString"].ConnectionString.ToString());
connection.Open();
String nEstno = Request.QueryString["id"];
int id = Convert.ToInt32(Request.QueryString["id"]);
string SQLquery = "";
switch (int.Parse(ddlQuantity.Text))
{
case 1:
SQLquery = "Select Quan1"etc...;
break;
case 2:
SQLquery = "Select Quan2"etc...;
break;
case 3:
SQLquery = "Select Quan3"etc...;
break;
case 4:
SQLquery = "Select Quan4"etc...;
break;
case 5:
SQLquery = "Select Quan5"etc...;
break;
}
SqlCommand Cmd = new SqlCommand(SQLquery, connection);
SqlDataReader Dr = Cmd.ExecuteReader();
if (Dr.HasRows)
{
gvEstQty.DataBind();
}
Cmd.Dispose();
connection.Close();
connection.Dispose();
}

I have a dataset that has two datatables. In the first datatable I have EmpNo,EmpName and EmpAddress. In the second datatable I have Empno,EmpJoindate, EmpSalary. I want a result where I should show EmpName as the label and his/her details in the gridview. I populate a datalist with the first table, and have EmpNo as the datakeys. Then I populate the gridview inside the datatable which has EmpNo,EmpJoinDate and EmpAddress. My code is
[Code]....
My Design is
<asp:DataList ID="Datalist1" runat="server" DataKeyField="EmpNo">
<ItemTemplate>
<asp:GridView ID="Gridview1" runat="server">
</asp:GridView>
</ItemTemplate>
</asp:DataList>
I do not get results in the gridview, instead have errors. I tried then placing the bound field
<asp:GridView ID="Gridview1" AutoGenerateColumns="true" runat="server">
<Columns>
<asp:BoundField DataField="EmpNo" />
</Columns>
It throwed an error stating / A field or property with the name 'EmpNo' was not found on the selected data source.

My entitydatasource is:

My gridview is written as:

[Code]....
I am a newbie at entitydatasource and have a few questions:
1. Currently, the gridview doesn't render. Why is that?
2. How do I wire up the gridview to grab the values of ddlsearch and txtSearch and return results using those values from my entitydatasource?
3. Ultimately, I want to encapsulate this gridview in a wizard step wherein the user checks items they want and those checked items are used in the next wizard step.

I have a page where I will insert all the data into the database. The page where I'm having problems is when I select an item from the checkboxlist it only displays one item. The data which is displayed is only the one that was inserted with one selected item from the checkboxlist. The following code is the page I'm using to try to retrieve the data from the database. I am trying to do is when a user selects the first, second, or third, or fourth item. The corresponding data appears in the gridview. In my current code, the record which has one item selected appears. If the user has more than one selected it does not appear. It comes up as empty. Is there a way I can do it?

Working on a site where a user does a search, it takes the input from the user and then runs an SQL command to return the data in a gridview for the user to see. I also have a button where the user can see all the results from the DB (this will be taken out later but for now the DB is pretty small) This is all working fine, but the problem I am having is that when you look at the page source the gridview populates everything in tables on the page. This makes it really easy to just copy and paste and get everything from my database. How can I go about displaying the information to the user in a gridview, but hiding the table information in the html page source?

I have a repeater bound to a datasource that servers as a list of birds. When the user clicks an item in the list the bird's image is displayed on the page. I want to change the background color of the item that is currently selected in the OnClick handler for the main item in my repeater's ItemTemplate.
I have changed the styling of controls prgrammatically before and it worked fine but in those cases i used the ID of the control to directly access it in my code behind file. But since this is some arbitrary item in a repeater I don't know it's ID at runtime, all I have is the sender object passed to the control's OnClick handler. So in my code behind file, I tried casting the sender object passed to the OnClick handler to the appropriate type and used Style.Add("background-color", highlitColor) but it failed to change anything.
I had a thought - maybe this sender object gets passed by value so all I did was change the Style of a COPY of the control item.
If this is indeed my problem, how do I start with a casted sender object in an event handler and get a reference to the actual control in order to change it's Style?
