Asp.net - Dropdown List To Filter Gridview?
Oct 21, 2011
I would like my gridview to be filtered by the dropdown list I have. It is pulling specific information from the database, so when you choose a value from the dropdown list, it should search through all the records and find only records with the ddl value in them.
The code that I am using in the codebehind for the SelectedIndexChanged is not right though. I get an error message saying 'Value' is not a member of 'Integer'. This is on the line dsCompanyFilter.SelectParameters.Add
It probably has something to do with the gridview not tying to the dropdown list properly, but I am not sure how to fix that code.
<asp:Content ID="Content2" ContentPlaceHolderID="body" Runat="Server"><br /><br /><br />
<asp:linkbutton id="btnAll" runat="server" text="ALL" onclick="btnAll_Click" />
[Code]....

This post is similar to one I have posted before about a dropdown filtering results in a gridview. Well now I need this dropdown to attach itself to a repeater that will filter results into a gridview. I have tried rptLetters.DataBind() in the code behind of the dropdown list, but that doesn't seem to be changing any of the letters at the top of the page when I click on different items in the dropdown list.The screenshot doesn't show enough of the products, but in this case it skips from G to L, and in the repeater the letters between G and L are still shown. I need to be able to get that repeater to recognize the letters that start each of the products associated with the company chosen.
<asp:Content ID="Content2" ContentPlaceHolderID="body" Runat="Server"><br /><br />
<asp:linkbutton id="btnAll" runat="server" text="ALL" onclick="btnAll_Click" />
<asp:repeater id="rptLetters" runat="server" datasourceid="dsLetters">

I have a gridview with a dropdown list that was created programmatcially. I want to have access to the selected value and to that row's Id. I have the dropdownlist created in *Gridview_RowDataBound* and I am able to use the text in the cell but my addHandler is never fired. Where do I give it the Add handler. I believe I can assign it the addhandler in RowCreated but how would I be able to set up the add handler if the button is created in rowdatabound?
[Code]...
It fits best in Rowdata bound because my dropdownlist items don't duplicate but I need to be able to use the addhandler I created.

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?

How do I filter my DataGridView with multiple checkboxes names? I want to filter in which region the suppliers are located. ex. RegionTable.Regionrow. And I have 4 different regions(checkboxes text name) I want to filter with. Compatible to use multiple choices in filtering.
So. Checking 2 of the 4 regions and pushing the filter button should filter the gridview after checked checkboxes. I have tried different methods for 4 hours and search the net but can't find any good method.

I have an ASP.net web page with VB code behind linking to an MS SQL DB. On the web page I have 4 DropDownLists and 1 GridView. Each DDL is populated with a SELECT DISTINCT query on 4 corresponding columns from 1 table in the DB. What I would like to be able to do is: when any of the DDLs have their selected item changed the other DDLs are updated. Crude example:

I have a dropdownlist that I want to populate with a specific value and specific text. I'm not using a datasource but I am manually making a connection and retrieving data in code. How can I populate this dropdownlist? If I read the data with a datareader and increment an array I only get either the value or the text. This is what I have so far, but it is completely wrong:
//connection string etc goes here
Dbcmd2.CommandText = "select dept,deptname from table"
Dim dr As SqlClient.SqlDataReader[code]....
How can I get this to work without having to create a class object for Department? Is there anyway or should I create the class object?
