Forms Data Controls :: Gathering Multiple Values From A Checkbox List
Dec 3, 2010
I was able to gather a value from a gridview based on a selected checkbox. However, I would like to be able to grab multiple values instead of just one. I tried using a for loop to gather my information and populate labels as a test. However, that caused an error. This is the code I currently have to use.
foreach (GridViewRow gvr in GridView1.Rows)
{
if (((CheckBox)gvr.FindControl("CheckBox1")).Checked)
{
lblTest.Text = gvr.Cells[1].Text;
}
}
How to gather multiple values and populate other labels? the other labels are labeled accordingly as lblTest2 and lblTest3. I currently am gathering my data from a gridview and only want to pull the StaffID from gvr.Cells[1].text.
I have a form with three Gridview's. ie. GridView1,GridView2,GridView3.Each gridview contains two templatefield and a boundfield.The first templatefield is a checkbox field and the second one is a labeltemplate with databinding to field "Usr_Id" and the third field is for Name.I have enabled paging for all the three girdview's and different data's are populated on form_load.how can i maintain the checkbox status while paging for all the three gridview's.ie, when i check checkboxes in two pages in gridview1 and checked three pages in gridview2 and so on,i should get the check state of all the gridview checkboxes maintained.I know to maintain the checkstate for a single gridview but when i am checking the pages in second gridview ,the checkbox values of some pages of gridview1 is lost
My problem is this "I have all the tools, VS 2005, 2008, 2010. I have every book, I have SQL server 2005 and 2008" I have all the tools, but I do not know what tool or technology to use when starting out learning all this. I juat do not know what book teaches what I need to do for something like below.
Here is my question:
I created an .ASPX webform that is to "Submit" to a SQL 2005 database. I gave this form to my DBA, and he has made up a Data Model. Now I have to figure out how to write the ASP.NET code so it will submit to the DB. My first issue is not knowing this:
1. "How do I loop through my CheckBox List", and then insert the values checked into a "Database Table" (Each Checkbox value MUST be a seperate row in the table, the DBA does not want a seperate column for each checkbox value)
2. The database is using stored procedures
3. My third issue is this: "I do not know "where" to put the "code". If you do resond to this,
Summary: I just need shown the code on how to "loop through" the CheckBox List on my form, and insert those values into a database table as seperate rows.
i use this to select one checkbox to isselected column how i convert this to multi checkboxlist to single column i use many ways more than 3 days without success
private void BindCheckBoxList() { DataTable dt = new DataTable(); SqlConnection connection = new SqlConnection(GetConnectionString()); try { connection.Open(); string sqlStatement = "SELECT * FROM boby"; SqlCommand sqlCmd = new SqlCommand(sqlStatement, connection); SqlDataAdapter sqlDa = new SqlDataAdapter(sqlCmd); sqlDa.Fill(dt); if (dt.Rows.Count > 0) { CheckBoxList1.RepeatColumns = 4; // set the number of columns in the CheckBoxList CheckBoxList1.DataSource = dt; CheckBoxList1.DataTextField = "Name"; // the items to be displayed in the list items CheckBoxList1.DataValueField = "Name"; // the id of the items displayed CheckBoxList1.DataBind(); //Setting the Selected Items in the ChecBoxList based from the value in the database //to do this, lets iterate to each items in the list for (int i = 0; i < dt.Rows.Count; i++) { if (!string.IsNullOrEmpty(dt.Rows[i]["IsSelected"].ToString())) { CheckBoxList1.Items[i].Selected = Convert.ToBoolean(dt.Rows[i]["IsSelected"]); } } } } catch (System.Data.SqlClient.SqlException ex) { string msg = "Fetch Error:"; msg += ex.Message; throw new Exception(msg); } finally { connection.Close(); } } private void Update(string name, bool isSelected) { SqlConnection connection = new SqlConnection(GetConnectionString()); SqlCommand cmd; string sqlStatement = string.Empty; try { connection.Open(); sqlStatement = "UPDATE handymen SET IsSelected = @IsSelected WHERE Name = @BizName"; cmd = new SqlCommand(sqlStatement, connection); cmd.Parameters.AddWithValue("@Name", name); cmd.Parameters.AddWithValue("@IsSelected", isSelected); cmd.CommandType = CommandType.Text; cmd.ExecuteNonQuery(); } catch (System.Data.SqlClient.SqlException ex) { string msg = "Insert/Update error"; msg += ex.Message; throw new Exception(msg); } finally { connection.Close(); } } protected void Page_Load(object sender, EventArgs e) { if (!Page.IsPostBack) { BindCheckBoxList(); } } protected void Button1_Click(object sender, EventArgs e) { string str = string.Empty; for (int i = 0; i < CheckBoxList1.Items.Count; i++) { if (CheckBoxList1.Items[i].Selected) { str = CheckBoxList1.Items[i].Text; Update(str, CheckBoxList1.Items[i].Selected); } } //ReBind the List to retain the selected items on postbacks BindCheckBoxList(); }
I'm trying to collect the checked boxes values in a data list. Need to collect the checked value (ie "1") and the data key value (cdID) together in an array to then insert into DB. Here's the Datalist:
i have a check box list control that is used for showing related files to some post.
what i want to do is set the databound items "checked" to true by default
then,
if a user unchecks some item and clicks the save button. then the selectedindexchanged will fire and i will do some logic.
what i have done is.
--Set All Databound items to "checked" --
[code]....
in the end i want the item that was unchecked to be removed (all other items will remain checked). but even before that, when the user control is loaded all the files that were bounded are being deleted by the index change event.
How to Filter Data/row from Repeater control in C.#Repeater control :---------------------All (15)shoes (3)shirts (12).Actually on click i want to filter data/row (posts) from Repeater control. Example: if i click on shoes 3 posts should display only but by default all 15 posts should display.

likewise i'm using 12 checkbox in a normal table(i.e <td> ).end of the form,there will be a button which should get verfy the checkbox's and set the correct value.
Protected Sub Button3_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button3.Click 'Sub Button1_Click(ByVal sender As Object, ByVal e As EventArgs) Dim s As String = "Selected items:<br>" Dim i As Int32 For i = 0 To chkbx(i).Count - 1 If chkbx(i).Selected Then ' List the selected items s = s & chkbx(i).Text s = s & "<br>" End If Next Label1.Text = s End Sub Sub chkLayout_CheckedChanged(ByVal sender As Object, ByVal e As EventArgs) If chkLayout.Checked = True Then chkbx(i).RepeatLayout = RepeatLayout.Table Else chkbx(i).RepeatLayout = RepeatLayout.Flow End If End Sub
Is this format is correct.i'm fresher and i dont know realy
I have a checkbox column in a Gridview that I would like to use to insert the value of one cell in the row into an access database. There will be a maximun of five cells allowed to be selected so there can be one value written to one field in the database up to the maximum of the five fields. The access database has five columns: Selection1 ,Selection2, Selection3 ,Selection4 and Selection5
When the checkbox is checked, the value of one cell (PliD) should be written to each field in the database. Ie: checkbox in row 1 should write PliD value to Selection1, checkbox in row 2 should write PliD value to Selection2, checkbox in row 3 should write PliD value to Selection3 and on depending on which checkbox has been checked. I am not sure how to get the value of the checkbox and write it into the corresponding fields in the database.
I'm creating an quiz application which queries the database and extracts the questions and choices. I use dynamically created controls such as a checkbox list and fill the values dynamically. How do I do this? Right now I have these functions:
array_random_init(); this creates a 10 element integer array from 1-20 - extract_question(i): this extracts a question indexed at i in DB, I created the controls and set the appropriate text in this function. - validate_question(i); this is called by button_click and validates the question i according to DB.
I understand I have to recreate the controls in Page_init on postback, but what should it look like? Do I need to add "if IsPostBack" in page_init, or do I create the controls in page_init() and reset their properties in page_load when I use extract_question(i)? Also, I cannot seem to clear the selected boxes on postback, I added page directive "enableviewstate=false" but it doesn't work.
