C# Files Array Gridview Dropdown?

Aug 20, 2010

Visual Studio 2008 C# I am wanting to create a webpage for my company that will list all PDF documents associated with a client. I have all the PDF's in the same folder, and the excel spreadsheet is in this folder as well. I currently have a gridview that populates the data from the excel sheet, so, that is working fine. It puts it into a table for view on the page. Now, lets say the excel spreedsheet has 2 columns (Company and Owner):

Companies: 1) ACME, 2) Slaters, 3) MotoUSA
Owners: 1)John, 2) Mike, 3) John

So, John is the owner of company #1 and #3 & Mike is owner of #2

I have PDF to associate with all these companies. They have a naming scheme of:
ACME - document1.pdf
ACME - document2.pdf
Slaters - document1.pdf
MotoUSA - document1.pdf
MotoUSA - document2.pdf
MotoUSA - document3.pdf
MotoUSA - document4.pdf

So every PDF will start off with the exact same company name and same spelling. What I am looking for is to have the gridview show the table of just the company name and owner, but allow the user to click on the company name and it dropdown to show only the PDF associated with that company. I am sure I will need an array for this and some editing of my gridview.

Web Forms :: Dropdown Value Used To Filter Another Dropdown Inside A Gridview?

Jun 11, 2010

I'm having a problem with using a dropdown to filter the contents of another drop down. The basic idea is:

Dropdown 1 = CountryList (Column1)
Dropdown 2 = StateList (Column2)

I read the contents of a CSV file and populate the gridview. The user then visually verifies that the data is valid and proceeds to upload to the database. To do some testing, i have intentionally changed spellings of country names so they DO NOT match the countrylist which the grid view then flags with a different background indicating bad data. The user then edits the gridview. The Country and state columns then show a drop down control populated with the country list and filtered states list based on countryID.

Here's the ASP.NET ASPX Source for the section of code that is dealing with the gridview

[Code]....

Here's the section of VB Code behind that deals with handling the "RowEditing", specifically the binding of the dropdowns

[Code]....

The proglem is that these dropdowns are ment to easily fix minor errors in data. When i intentionally changed the spelling of "Canada" to Canadaa", this has no corresponding CountryID in the table and the ddlEdtStateID Dropdown's datasource filter does not work. I tried setting the datasource to nothing if a valid CountryID was not there and then i tried to use the SelectedIndexChanged event for the ddlEditCountryID to programmatically set the datasourceID for ddlEditStateID but when i try using CType(FindControl("ddlEdtStateID"), DropDownList) to set the DataSourceID, it does not find the control.

If the Country does not exist, then i just want the stateslist dropdown to say "select a country" but when a valid country is selected, it should display the filtered list for that countryID. Right now, if bad data is entered for the country, then the program crashes when it tries to populate the state drop down. I want it to just say, select a country when the countryID is not valid.

Gridview Cell Value And Array List

Nov 25, 2010

When I am tryng to pass the gridview cell values to an array everything is perfect but the array is empty after executing the code. When I see through debug mode the index of selected row also is fine, i.e. when I select two rows using checkbox among 1000 the count shows exactly 2 in the array but the data is empty. I'm not able to get the cell value from the gridview.

protected void Button2008_Click(object sender, EventArgs e)
{
ArrayList checkedItems = new ArrayList();
foreach (GridViewRow row in this.GridView1.Rows)
{
if (((CheckBox)row.FindControl("cbRows")).Checked == true)
{
checkedItems.Add(row.Cells[12].Text);
}
}
Session["CheckedItems"] = checkedItems;
Response.Redirect("About.aspx", true);

Asp.net - How To Populate GridView.DataKeyNames, Constructing Array From Within A Loop

Mar 10, 2010

I have to set GridView.DataKeyNames(This is really a question about the syntax for a string array, in VB.Net.)

I am discovering the PrimaryKey columns names from within a loop, ie:

For Each fld As IEntityField In Me.llbDataSource.EntityCollection(0).PrimaryKeyFields 'fld.Name ' this is where the column name is stored, so I have to get this into an array Next I can not use this syntax.

GridView.DataKeyNames = new string() { "PowRatHP", "Voltage", "Phases", "Poles", "Drive" }

So, basically, how does one declare a string array (as required by GridView.DataKeyNames), and then populate the elements of the array from within a loop?

Forms Data Controls :: How To Set Selected Value Of Dropdown In Gridview After Gridview Databound

Nov 30, 2010

I have a gridview with dropdown boxes. As soon as the complete gridview is databound, I want to loop through ALL the rows and set the values of the dropdown boxe in a row based on the value of another column in the same row. The gridview is databound, all data shows up. The condition "If ddl.Items(j).Value = searchstring Then" evaluates as true, but somehow the selected item in the dropdownbox is NOT changed and remains "<ignore>"

Binding GridView To Array Of Strings - Error / A Field Or Property With The Name '!' Was Not Found On The Selected Data Source

Aug 19, 2010

I know that you can use exclamation sign to bind array of simple types (like string) to GridView like this

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="false">
<Columns>
<asp:BoundField HeaderText="Array Field" DataField="!" />
</Columns>
</asp:GridView>

But this doesn't seem to be the case with DataNavigateUrlFields

<asp:HyperLinkField DataNavigateUrlFields="!" DataNavigateUrlFormatString="RoleInformation.aspx?role={0}" Text="Manage users" />

and I get following error:A field or property with the name '!' was not found on the selected data source.

.Net GridView With Dropdown List?

Sep 7, 2010

As my previous question didn't seem to have much popularity, I decided to change completely the way I approached the problem. Now my issue is that I still have TABLE1 with a foreign key FK, but what I want to do now is have the FK column in the GridView display Dropdown Lists. The Dropdown Lists should have their Text property bound to FK in TABLE1 but they should be populated by the different values of FK (stored in TABLE2).
