GridView Control Is Only Partially Populating Itself

Sep 27, 2010

[code]Whenever my GridView populates, if there is no value to return from my _dataSet for a field, my GridView stops populating after that. Shouldn't it skip that and continue populating the rest of the grid? It seems the GridView won't accept an empty/null value. is?

Asp.net - Populating A Gridview With A Button's Click Event?

Dec 7, 2009

I have a page that has two dropdownlists(one for the locations, and the other for departments), an employee search textbox and a button. On the other page, I have a gridview. Now, what i want to archieve is that when a user types an employee's name in the textbox control, selects a location from the location dropdownlist, and a department from the departments dropdownlist, and click the button(search), the gridview on the other page must show the reqiured information of a SINGLE employee. Only one row must show.

I have created a database for the employees. I know how to do this with the autopostback but i have not tried it using a button's click. NB: the gridview should show only one row of a selected employee. I'm using ASP.NET VB

C# - Dynamically Populating Column Headers In A Gridview?

Mar 6, 2012

I have a vb.net website with a gridview that currently has exam questions displaying vertically in each row like this:

Name question answer
-----------------------
Joe question1 answer1
Joe question2 answer2

[code]....

But I would like to change it, so that each question is a header, like this:

Name question1 question2 question3
----------------------------------
Joe answer1 answer2 answer3
Jill answer1 answer2 answer3

This makes it more readable since each user is only listed once.I would like to stick with a gridview instead of rewriting all my code.I am actually binding my data to the gridview via some other programmers class. I am using LINQ like this:

Return (From entry In report.FetchAllEntries()
Select questionID = entry.Question.QuestionID,
userID = entry.Session.User.ID,

Populating A Combo From A Dataset?

Dec 11, 2011

I am trying to get my head around datasets, etc. The following code pulls data from an sql server and stores it in a data set. I then set the grid's datasoure to this data set. Now I want to populate a combo box on 'form load' with information from a field (surname) within the authors table.How do I approach this? I can do it in design mode but I want to do it in code as I feel you get a better understanding of what is happening under the hood.

Asp.net - Dynamically Populating A DropDown Template Control In A Gridview?

May 3, 2012

I have a GRIDVIEW with columns, one of which contains a CSV of possible values for the dropdown that must appear on each row.

Private Sub GridViewParameters_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles GridViewParameters.RowDataBound
If e.Row.RowType = DataControlRowType.DataRow Then[code].....

Depending on whether the type of control is a dropdown, textbox, or check box (feined in the table) it hides or shows the relevant control type. If it is a dropdown it needs to get its values from a CSV in a corresponding column. I have a SP that returns a these in table form if passed the id of the relevant row.How do I get that is from the gridview to pass to the drop down and load it correctly?

Populating A Dataset From The Tables That Are In An Access Database?

May 7, 2010

I have a database that has tables in it. Tables can be added to this databse programatically as well as the data that needs to be in those tables.I need to be able to query that database to get what tables are in it, place the names of those tables into a listbox so that when a user clicks on the name of the table, It will update a DataGridview with the data that is in that table in the database.I assume that you would need to build a dataset at runtime based off of what tables are in the DB, but i have no idea how to do this.

SQLDataAdapter Fill Dataset/Load Gridview/Update?

Mar 9, 2011

I'm still in my novice stages of .net development, and I think I may be trying to make something too complicated.In VB.Net 2008, I'm using a SQLDataAdapter to Fill a dataset with records being returned from a Stored Procedure (SQL Server 2005).I'm using that dataset as the datasource for a gridview. Up to this point, everything is great and I understand what's happening.I'm getting ready to make my first-ever attempt at updating the data in thegridview and then pushing the updates back to the SQL dB.Here's where I'mgettingconfused...to cut to the chase, what's the simplest way to load the updates back into SQLServer?

Improve Paged Gridview Performance : Huge Underlying Dataset?

Jul 1, 2010

I'm currently working with a gridview that has a huge underlying dataset.I'm almost certain that I saw something about a new facility in Visual Studio 2010/.NET 4, which would improve the performance (e.g. doesn't download all the data on databind, but rather only what data required for current page). My guess would be that it was using AJAX.I didn't need it at the time I saw it, and now I can't find it, even though I've been hunting online for a while.

IDE :: Dataset Code Behind Datatable.ColumnChanging Event Firing / But Dataset.HasChanges Property Not True

Jan 28, 2010

I have code running in the Datatable.ColumnChanging event in my dataset. This dataset underlies a form and conventional drag/drop controls are in place for data entry.when the event triggers and runs, I am running code in the form that checks the dataset.HasChanges property. It is showing False. But this is immediately after the ColumnChanging event has been triggered.Okay, I see by others posts and MSDN that .HasChanges will only be true after moving off the row with the changed column. I have also noted lots of discussion about the advanced binding property of DataSourceUpdate Mode, but that does not address this issue.I guess I can do this by checking the state of the row for the binding source. Just seems odd that the event behind the dataset can be triggered and that does not change the dataset.HasChanges property.
