VS 2010 - LinkButton CommandArguments Changing In Gridview Bound To Datasource

Jun 23, 2011

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

<%# Eval("PartNumber").ToString() + "|" + Eval("ID").ToString() %>

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?

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.

C# - Have A Gridview, Bound To A DataSource With The Query?

Dec 24, 2010

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:

e.Row.Cells[1].Text = "<a href="http://www.domain.com/page.aspx?userid=" + e.Row.Cell[0].Text + "">" + e.Row.Cells[1].Text + "</a>";

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.

DataSource Controls :: How To Export The Current DataSet Bound To A Gridview To Excel

Mar 12, 2011

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:

http://msmvps.com/blogs/deborahk/archive/2009/07/23/writing-data-from-a-datatable-to-excel.aspx

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?

VS 2010 / Checking Conditions With Dropdownlist On Each Item Bound?

Jul 21, 2011

I am binding Dropdownlist from sqldatasource. Is it possible to check conditions with Dropdownlist on each item bound, based on the select command.

Code:
<asp:DropDownList ID="DropDownList1" runat="server" DataSourceID="SQLDataSource1" DataTextField="emp_name" DataValueField="emp_id"></asp:DropDownList>
<asp:SqlDataSource ID="SQLDataSource1" runat="server" ConnectionString="<%$ConnectionStrings:ConnectionString1 %>" SelectCommand="select emp_id,emp_name,status from emp_master"></asp:SqlDataSource>

In this example code, when binding if the status of the employee is OffDuty then it must be highlighted in DropDownList.

VS 2010 - GridView DataSource Edit

Jul 31, 2011

I have a DataView that is bound to a DataSource, which gets its data from a SQL database.I'm converting a desktop app to a web app and I've been able to duplicate the data query side, but I'm having a hard time inserting a new record via the data source. In the desktop app, I don't use a data source. I have a class I created that inserts a new record, but the upkeep is extremely time consuming, so I'm switching to the datasource.When I assign the datasource, I selected the SQL statement/stored procedure option and created my INSERT command via the Query Builder.

The problem I'm running into is that I don't want a SELECT statement. I just want a plain GridView so I can select Edit, fill in the data and then call InsertParameters.If I don't add a SELECT statement, it won't let me finish the wizard and an invalid one throws an exception. The only other thing I could think of, was to call SELECT and set a WHERE based on a column whose value is null. The app runs, but the GridView doesn't appear. How I can only do an INSERT?

VS 2010 - Changed LinkButton To Anchor

May 2, 2012

This used to be what my code looked like:

Code:
<asp:Repeater ID="rptrDocuments" runat="server"
onitemdatabound="rptrDocuments_ItemDataBound" onitemcommand="rptrDocuments_ItemCommand" >
<ItemTemplate>
<tr><td class="approval-item">
<asp:RadioButtonList id="rblApprove" runat="server" RepeatLayout="UnorderedList">

[Code].....

I was working with a linkbutton in a repeater. I was resolving the linkbutton like so in the code-behind:

Code:
// - It's not this anymore. Changed for Jim's styling.
//LinkButton linkPdf;
//linkPdf = (LinkButton)e.Item.FindControl("lbLinkToPdfFile");
//linkPdf.Text = drView.Row.ItemArray[IDX_DOCUMENT].ToString();
//linkPdf.CommandArgument = drView.Row.ItemArray[IDX_DOCUMENT].ToString();
// - Now it's this:
// <span class="options"><a href="file:X2">View File</a> | <a href="mailto:X1">Email Sender</a></span>

The designer had to style this page and asked if it could be an anchor instead of a linkbutton. I said sure. But now I am not sure how to "find" it in the code behind and set "a href=file:the file that needs to open when they click the link". I'll have the same problem with the email link.

VS 2010 Linkbutton Click Event In UserControl

Oct 17, 2011

I created a usercontrol I use to build up a list of at runtime. Each instance represent one category, and it will have a title, description and a button taking the user to the page displaying all articles for that category.

The control's members:

Code:
public string Title { get; set; }
public string Description { get; set; }
public int CategoryId { get; set; }

And the markup:

Code:
<h4><a href="#"><%=Title%></a></h4>
<div>
<p><%=Description%></p>
<p>
<br />
<asp:LinkButton CommandArgument="<%=CategoryId %>" runat="server"
CssClass="small btn red fr" onclick="LinkButton_Click">Go To <%=Title%></asp:LinkButton>
</p>
</div>

The code show's just fine, but the click even never fires when I click the button:

Code:
protected void LinkButton_Click(object sender, EventArgs e)
{
var x = sender as LinkButton;
string z = x.CommandArgument;
}

Obviously doing it wrong, but then, did not touch webforms in a long time.

VS 2010 - Changing Menu With Masterpage

Sep 3, 2011

When I began my first ASP.NET project, I didn't know about Masterpages, which was a pain. Because I had to manually change each and every link on all of my web pages. This was all mainly for the top menu and side menus.

But now that I'm using a master page, I think it's going to be much easier. But, I'm running into an issue.

When the user loads default.aspx, they see the following on the top menu.

Which is how I want it. But, what if they click one of the links? Before, I just updated that code to make the button of that page the active one. But, if they're all inheriting the same page, how do I commit this changes? I don't want to omit that part and manually change it on each page, because that would beat the entire purpose of doing this.

I also don't want to create another master page for each link. That would also beat the purpose.

VS 2010 Changing From DataAdapters/DataSets To DataSources

Nov 13, 2010

How do you control database server access when you use datasources in VB 2010?How do you access multiple tables from a store procedure using datasources?

Explanation:My experience is with VB.NET for the most part. I've written a lot of apps drawing data through dataadapters into datasets and processing them to provide reports in aspx.

I'm starting to work in VB 2010 and those elements are no longer available. What appears to be the weapon of choice is the datasource.What I'm not seeing: 2 important things that I can't work without:

1. Control over when the database server is hit with a connection request; daMyQuery.Fill (MyDataSet) was an explicit command that I could use to collect my data on demand. From that point on, I could use the dataset as I wished to populate whatever controls or structures I wished - the database server was no longer needed and wasn't hit by my apps until another pageload.

2. Multiple Tables in a query result; This must be there, I just can't find the method by which to reference different tables in my SQL output. Previous, I would have a dataadapter which would use a stored procedure to deliver a dataset of multiple - sometimes many - tables for use in the application. I can't find the equivalent on a datasource.

So my two big-ticket needs - requests for assistance, really - are listed above: How do you get at multiple tables returned from a stored procedure;and;How do you keep datasources for hitting the dbserver whenever you use it if there is no equivalent to a 'fill' method?

I guess another - how would you walk through the rows of a dataset?

VS 2010 - Error Changing Framework Of Windows Service

I have a deadline to install my windows service NOW. I developed it in VS2010 and chose the .NET 4.0 framework.

VS 2010 - Changing Treenode Backcolor Dynamically In Code

What I need to do is perform some kind of decision statement and when true I need to change the backcolor of a treenode to grey, so that it has a grey box around the whole text. There is no backcolor property for the tree node and I don't need it applied all the time so I don't think a CSS class will do this.

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

How To Access The Bound DataSource Item In The ListView's DataBound Event

Sep 22, 2010

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.
