I'm using a GridView to output some information regarding an account, specifically account balances. Problem is, if there is no balance linked to the account, I need for the grid to simply display 0 for each column. EmptyDataText isn't sufficient as the columns still need to be listed, but just have the value 0.
After researching it seems like I will need to add a dummy row to the gridview if it is empty, but how do I do this using C# and ASP? Quick note as well, not sure if it's relevant but the grid will only ever contain one row.
I want to change the text of gridview empty data template based on diff scenerio's.

I would like to find controls in the detailsview control placed in the EmptyData Template of the gridview. I am trying to create Insert new record for the gridview control.
1. If there are existing records in the table - works fine and sets my two values: I placed Detailsview and Insert Button in the footer of the gridview. I needed to set the values of two fields. When I click on the Insert button it saves new record and sets the field with the value (code attached - works fine). I also have a popup extender that opens detailsview - this works just fine.
2, If ther are not records in the table - saves record but cannot find and set controls on the detailsview Same thing setup in the EmptyData Template. The record is saved but I cannot Find and set the field value on the control.
1. Link button (on click) in the gridview footer (works fine)
protected void LinkButton1_Click1(object sender, EventArgs e)
{
string zupa1;
zupa1 = ddlSelectEmployee.SelectedValue;
try
{
DetailsView zupa = (DetailsView)gvTraining4.FooterRow.FindControl("DetailsView1"); TextBox zupa2 = (TextBox) zupa.FindControl("txtInsertEmployee");
zupa2.Text = zupa1;
}
catch
{
}
DetailsView dettraining = (DetailsView)gvTraining4.FooterRow.FindControl("DetailsView1");
TextBox training = (TextBox) dettraining.FindControl("txtTrainingType");
training.Text = "4";
}
2. EmptyDataTemplate.FindControl - can save record but cannot access txtInsertEmployee and txtTrainingType
DetailsView zupa = (DetailsView)gvTraining4.EmptyDataTemplate.FindControl("DetailsView1");TextBox
zupa2 = (TextBox)zupa.FindControl("txtInsertEmployee");TextBox
training = (TextBox)dettraining.FindControl("txtTrainingType");"4";
If the gridview binds to empty dataset, I need to still show a gridview so that users can ADD more using the textfields in the bottom of the footer template. Since the gridview is empty it won't bind not allowing rendering of the <footer template> I guess I should create a empty dataset if the gridview is empty. How do I check for this and can this be done in GridviewRowEventArgs

I'm writing a gridview in VB.NET that is bound programatically in the Page_Load function. I am binding the data in the 'If Not Page.IsPostBack Then..." structure. And as you can see, I'm using TemplateFields instead of BoundFields. And I need to access the e.OldValues in my RowUpdating function, but they come up empty.

View 2 RepliesI have a gridview and i wanted to add a row when the gridview is empty, so that the header would be shown anyway. I have read about it on the web but i can't quite understand where exactly should i add the row.
My grid is binded by a sqldatasource. I am already adding a second header for the grid (to display some filters, and they need to be shown even if there are no results so that the user can perform another "search"), on rowCreated event, so, where am i supposed to add the row? Which events are fired even if the gridview is empty?
provide an example to do that... "Hide column if row is empty" in Databound()
datasource could be .1
coulmn: id-value1-value2-value3
row: 1-4-3-NULL (output: hides row value3) because the value is NULL
.2
coulmn: id-value1-value2-value3
row: 1-4-NULL-NULL (output: hides row value2,value3)

When retrieving values from Gridview empty cells, you will get " " instead of a empty string or null.
Someone once change the columne's properties as following, but it doesn't work
ConvertEmptyString > true

One solution is to check if the cell value is " ". If so, assign it an empty string. But this approach looks awkward.

I've got a gridview in which I have a footer that I use to insert rows into the grid. However, if the grid is empty no data is displayed (including the footer). Is there a way to still show the footer row so a user can insert additional rows into the grid despite it starting out as empty?
