Forms Data Controls :: Adding Row To GridView If Data Source Is Empty
Oct 12, 2010
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 have a gridview with two bound fields. On clicking a button i want to display the values in first row of gridview in two textboxes. But if gridview cell is empty i am getting the text in textbox to which the value of cell is given as -' 'i know my problem will be solved if i use the template fields instead. But i want a solution while maintaining the bound fields ,if any.
How to display empty GridView to insert new record if no data retreived for some record on the result from data table?Actually i am trying to give a user an option to add recrod from Gridview. On result of some query it is perfectly displaying data and a footer row with the insertion textbox but when there is no data in the gridview it is not displaying. It should display with footer having insert textbox.

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 have in my code a gridview that I redirect to excel, it works fine when I have data in the data set. waht I want is to show column headers when there is no data right now what i get is empty sheet.
I want to make serach functions which are looking HDD size and RAM size. I given the parameters with decimal. In SqlDataSource and testing gridview, it is working. However, it is not working that it shows empty row at browser. I have some error gridview or SqlDataSource. I cannot find it currently.
I have a gridview with daatsource from MembershipUserCollection. When my collection doesn't contain any records the gridview just disappears. I want to display the empty gridview indicating no records exist rather than the grid just become invisible.
I have a gridview and I have an edit template for one control. I have a drop down box in this edit template so that you can select a value from it and then when you hit 'Update' the value from the drop down box is committed to the updated record. Unfortunately when I do hit the update button I get a fault that the "Status" field cannot be null.
Here is the code that picks the value from the drop down value and assigns it to the new values list:
i am working on a website,As i am new to coding i got a problem in it. It was,I hav a gridview in which i am adding the details about a college, and in that i had a buton ("btnReservation") on clicking it another grid will be appeared in which, i hav to enter the reservation details so, till this step it is working fine, but if i enter one college details and clicking on the btnReservetion the grid is being dispalyed and i am able to enter and save the data, But if i enter the details of another college and clicking on the btnReservation, the rows which i hav already entered in the Reservation grid for the previous record are not being Refreshed and are remaining the same,So now i hav to make the gridview datasource null.

I have a gridview in a user control which I'm using to display a list of items. The data source is a list of objects (not using ObjectDataSource). I have paging enabled on my gridView. The trouble is that I am forced to rebind my grid in my paging method, otherwise the grid loses all it's data when a user clicks a page button. Is there a good way of binding to an enumerable list such that the values are reused on postback?
Is it possible to use dynamic query filters with a gridview using a stored procedure as a data source? What I'm thinking of is a search page where there are multiple controls to enter in a search string and a radio button for the AND/OR query filters between the various controls. If not, what would be the best way to allow a user to select an AND / OR with a group of different query controls?
Here is the page I have created thus far using a view and no AND/OR option. I but I can't get it to work with my SP, also listed below:
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)
I am trying to setup a page to print Address labels. I want the users to specify how many labels to skip down so they dont have to use a fresh sheet every time. I want to be able to insert the blank data above the other rows but not edit or modify. I will be exporting the gridview as a PDF for printing after.
