C# - Get Rowdata As Bound To The Gridview Datasource?
Jan 5, 2011
My GridView is bound to a certain DataSource. Each row only shows 4 of the 8 possible items. Lets say we have name, adress, phone, fax, email, country, province and age. The GridView would only show name, email, country and age, but I want to access the province and adress bound to a row.
I got a custom GridView, with an onclick event which updates an panel (through AJAX) which shows additional information about the selected row.
i think this maybe an easy one...I have a Gridview, bound to a dataSource with this query:select userid, name, phone from usersI need to change the content of the Name cell to a link, like so:<a href="http://www.domain.com/page.aspx?userid=12345">User's Name</a> so OnRowDataBound i'm doing this:
It all works fine this way. My problem is that i don't want to display the UserId column in the Gridview, but when i attribute it (asp attribute or server-side) Visible="false" to the BoundField UserId, i can't capture it's value to build the Name Cell.
I have a Gridview that displays some data I am pulling from a SQL Server database. The stored procedure that runs the query accepts a table valued parameter. I am unable to find a way to pass this structure to an asp:SQLDatasource so I have been manually creating the datatable and then binding my Gridview to it. The DataType I am using in the code-behind to pass into the stored procedure is a System.Data.SqlDbType.Structured type.
Each Gridview row has an asp:LinkButton with a CommandArgument value that looks like
Each LinkButton calls back to a function in my code behind that accepts the CommandArgs, does some work, and redirects the user to another page.
Since I am manually binding the Gridview to the Datasource when the number of records exceeds my paging size and the user changes pages or sorts the Gridview, the CommandArgument value changes to the wrong row and I get bad data back from the CommandArgument. how to pass a System.Data.SqlDbType.Structured type into an asp:SQLDataSource but if that is not possible how I can work around this?
I have a GridView populated by an ObjectDataSource. I also have several DropDownLists filtering the ObjectDataSource. I found a link providing a way to export a DataSet (or DataTable) to Excel here:
ow I can ensure that filters applied to the ObjectDataSource when the method is called are applied. In short, how can I ensure what the UI is displaying is what the file will include when exported?
When the rows are not in edit mode the fifth columns shows a link and while editing it shows a dropdown. To select the correct item in the dropdown I use the second column that has the ID that came from the database.
The problem is that after changing the item and saving it to the database, this column value doesn't change. How can I do it after the grid.saveRow(lastSelection, false); ?
I have the following code that I wasnt to alter the Dataset before it is bound to the dropdown list.
[Code]....
What I would like to do is ALTER the dataset for the Parent (dropdown list - ddlRT). I need to format and disable certain topics. I have a script I create before I added the datarelations.
I have a sqlDataSource to populate a grdiview ( simple ) . When I set the sql control to a stored proc that has 4 parameters and person a select * from table ignoring the paramaters it doesn't work. No rweturned results.
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 know the question has already been posted here but we didn't get to an real solution.I have bound my ListView to an SqlDataSource and I want to write some text in a control present in the view created in the LayoutTemplate depending on some properties of the rows returned.Obviously, I'm using the ItemDataBound event to feed my items but this is not the point.
The spontaneous solution was to bind the ListView.DataBound event and access the raw datasource (a DataTable?) and do the required calculations.I inspected the Items property and, despite it was not empty, the related DataItem property was null.The only work-around I can come to is to execute the calculations in the ItemDataBound event and accumulate the result in some private fields. But it's really ugly to see and makes harder to get some of the required values.
How do I bound a Label to a datasource and its field?I got set up the datasource to a gridview, but don't know how to bind a label to the same datasource.
I've been working on a webform to pull data from an oracle database v10. I can create a gridview1 with Selection enabled and it will populate with data without a problem. However when I create a second gridview and bind with a control to the first gridview, I get the following error at runtime when I click on one of the Selects.
I have a FormView bound to LinqDataSource, that is intended to allow editing of a single product's details, that is selected from a GridView. The LDS has a Where parameter set to point to the GridView control (i.e. a ControlParameter).
This was a pretty disappointing moment - when databinding, using Eval("Contact.LastName") would work. It nicely evaluates the related Linq object's member LastName. If the "Contact" object is null, no error is thrown... instead the field is simply null.
However, the same does not hold for sorting - if there exists a null entry (this object does not have a Contact) then the LinqDataSource throws a NullReferenceException. This means that, if you ever have nulls on your foreign-key objects, you can't use sorting headers in the ListView.
This makes the feature moderately useless - I have to roll my own properties for every single field I'd ever want to sort on. That's insane.
I'm having some evils trying to get my GridView control to behave. I have the below code, which successfully displays all the files in the directory. However I require two changes, both of which I am struggling with:
a) Currently the URL you get when clicking on the URL field is [URL] (ie my home directory with the filename). What I require is that the 'Display Text' be the filename only, and the URL be my desired text followed by the filename eg: [URL]
b) I want only to see the files that start with a certain prefix eg "Pay". I can do that with something like: string[] filelist = Directory.GetFiles((@"C:MFData","Pay*.*"); but this doesn't like to bind to my Gridview!
const string DocumentFolderPhysicalPath = (@"C:MFData"); const string DocumentFolderUrl = (@"C:MFData"); [URL]; ; // now it is hardcoded but you could retreive it automatically HyperLinkField hyperLinkField = new HyperLinkField(); hyperLinkField.DataTextField = "Name"; hyperLinkField.DataNavigateUrlFields = new string[] { "Name" }; //Would like this to work! //HyperLinkField hyperLinkField2 = new HyperLinkField(); //hyperLinkField2.DataTextField = "Destination"; //hyperLinkField2.DataNavigateUrlFields = new string[] { (@"C:MFData") + "Name" }; GridView1.DataSource = GetDocuments(DocumentFolderPhysicalPath); GridView1.Columns.Add(hyperLinkField); GridView1.DataBind();
private System.IO.FileInfo[] GetDocuments(string physicalPath) { System.IO.DirectoryInfo directory = new System.IO.DirectoryInfo(physicalPath); if (directory.Exists) { return directory.GetFiles(); } else { throw new System.IO.DirectoryNotFoundException(physicalPath); } }
I have a repository that contains all of my LINQ queries for this project that I am working on. I am able to get the LINQ results to a DataTable and bind that to a gridview for displaying the data. Now I need to make the gridview sortable. I have set AllowSorting="true" and I have the OnSort event handled in a routine in the codebehind.
from my collection entity I am getting DayOfTheWeek like 1,2...7. 1 for monday , 2 for tuesday like that. Where should I place condition so that in grid view it would display day name rather than corresponding code.
I have an ASP.NET GridView control in a Web Form. For the sake of simplicity, I will say that this GridView is defined as follows:
[code]...
When each of these rows is bound (a.k.a. during the "myGridView_RowBound" event), I want to get the ID, Name, and Age values. My problem is, I cannot figure out how to get the "ID" value. The reason why is because it is in an invisible field.
I have an aspx page with 2 controls on it - a GridView bound to a SqlDataSource control.Am I correct in thinking this is 2-tier ?If I were to replace the SqlDataSource with an ObjectDataSource, and make the database connections/calls/queries via a class in the App_Code folder, this would be 3-tier, right ?
I have to set maximum length for bound field in an editable gridview. For this i have used data format string property and also given ApplyFormatInEditMode="true" still it accepts invalid input. The gridview does not have template field, it contains bound fields only. I have written OnRowEditing and RowUpdating events. The dataformat string is DataFormatString="{0:N0}" but it accepts '2352345234523454352345' input also and displays server error while updating in database. I want to spcify maximum length for the textboxes generated dynamically when Edit button is clicked.
I have a gridview which is bound to a DataTable. When I try to sort the gridview, it goes blank. How can I enable sorting this gridview? I know this question has been asked before, but what I'm looking for is an explanation of how to do it. Perhaps with a simple example.
I have read that I need to put some code in the on_sorting and/or on_sorted events, but I don't understand what needs to go there. Again, I want to understand the method of accomplishing this, I don't just want a giant block of code.
I'm hacking my way through ASP.Net WebForms, coming from VB.Net WinForms. I was hoping the transition would've been more seamless... it is not.
I have a GridView (Paging enabled) bound to a DataTable, filled with Joined tables from an Access 2000 DataBase.
The GridView and DetailsView are bound to the same DataTable.
In the GridView's SelectedIndexChanged Event I have the following:
vb.net Code:
' dtvSelected is the DetailsView' dgvJobTOF is the GridView Me.dtvSelected.PageIndex = Me.dgvJobTOF.SelectedIndex
When the page loads the first item in the GridView is also displayed in the DetailsView.
I've added a "Select" button in the GridView and when it is clicked the Data in the DetailsView remains the same regardless of the selected GridView row.
