Forms Data Controls :: Maintaining 12 Rows In A Gridview

Nov 27, 2010

I have a List box that displays my Vendors, and then I have a Gridview that shows payments made to those vendors. Is there any way of making the gridview always show 12 rows, regardless if 4 payments were made or even 0 payments have been made ?

Forms Data Controls :: Maintaining Gridview Row Height?

Nov 4, 2010

while using gridview whenever I go to edit an item it increases the row size - but this is because I have a multiline textbox as one of the edititemtemplates. It also increases the size of every row to the same size as the one that is being edited. Is there any way to keep the rest of the rows the same initial height and have an increased size just for the row being edited?

Forms Data Controls :: Maintaining Selected Values In DropDownList While Paging In GridView

Jan 8, 2011

I have a problem with keeping the selected values in DropDownLists in rows in GridView while paging. I have this code behind:

private void RememberOldValues()
{
ArrayList LinijaIDList = new ArrayList();
int index = -1;
foreach (GridViewRow row in GridView1.Rows)
{
index = (int)GridView1.DataKeys[row.RowIndex].Value;
if (Session["equal_ITEMS"] != null)
LinijaIDList = (ArrayList)Session["equal_ITEMS"];
if (row.Cells[0].Text == lineTextBox.Text)
{
if (!LinijaIDList.Contains(index))
LinijaIDList.Add(index);
}
else
LinijaIDList.Remove(index);
}
if (LinijaIDList != null && LinijaIDList.Count > 0)
Session["equal_ITEMS"] = LinijaIDList;
}
protected void Button1_Click(object sender, EventArgs e)
{
//Session["equal_ITEMS"] = null;
RememberOldValues();
GridView1.AllowPaging = false;
BindGrid();
//RePopulateValues();
DataTable dt = new DataTable();
dt.Columns.Add(new DataColumn("LinijaID", typeof(int)));
dt.Columns.Add(new DataColumn("Ime", typeof(string)));
ArrayList LinijaIDList = (ArrayList)Session["equal_ITEMS"];
//if (LinijaIDList!=null)
//{
foreach (int LinijaID in LinijaIDList)
{
foreach (GridViewRow row in GridView1.Rows)
{
DropDownList Ime = GridView1.FooterRow.FindControl("ImeDropDownList") as DropDownList;
int rowID = (int)GridView1.DataKeys[row.RowIndex].Value;
//string Name = row.Cells[1].Text;
string Name = Ime.SelectedValue;
if (rowID == LinijaID)
{
DataRow dr = dt.NewRow();
dr["LinijaID"] = LinijaID;
dr["Ime"] = Name;
dt.Rows.Add(dr);
}
}
}
GridView1.AllowPaging = true;
Session["equal1"] = dt;
Response.Redirect("CheckedRowsPage1.aspx");
}
// else
//{
// GridView1.AllowPaging = true;
// Session["equal1"]=null;
// }
}

When I insert a value in the TextBox2 and want to select only the rows from the GridView from different pages which have value in the first column the same as the value in the TextBox2, after clicking on Button1 I get this error:

Exception Details: System.NullReferenceException: Object reference not set to an instance of an object.

State Management :: Maintaining Viewstate On Gridview With Controls?

Jan 14, 2011

I have a gridview with results from a database query and columns where I add linkbuttons to individual cells.

something like:

Dim LB2 As New LinkButton

LB2.Text = "title"
LB2.CommandArgument = "argument"

AddHandler LB2.Click, AddressOf LaunchDocument

GridView1.Rows(i).Cells(10).Controls.Add(LB2)

There is a lot time involved in determining what cells get the linkbutton and I want to avoid going through that process on a postback when a user clicks one of the linkbuttons.How can I maintain these controls in the gridview after a user clicks a linkbutton and a postback is done?Right now the application has to go through the process all over again.

Jul 30, 2010

Having a bit of difficulty working this gridview update problem out - I have managed to get edit/update function working but instead of only updating the current gridview row it is updating the whole table I believe this is due to a missing where statement on my Update statement - to single out the row index of my grid row.When I configure my sql datasource I am using custom statements Here is my update statement

UPDATE SimpData SET store_nbr = @store_nbr, date = @date, data_type = @data_type, acct_1 = @acct_1, amt_1 = @amt_1, acct_2 = @acct_2, amt_2 = @amt_2, acct_3 = @acct_3, amt_3 = @amt_3, cheque_nbr = @cheque_nbr, cheque_amt = @cheque_amt, gst_hst = @gst_hst, qst = @qst, comments = @comments, uploaded = @uploaded

I am using a Gridview on a webform. Got the editing/updating all working correctly. Problem is, all the data is on one row and it is alot of data. I thought about splitting the data into 2 gridviews but then all of the employee data isn't lumped together like the higher ups want.

I have done research on a DataRepeater as it will give me the formatting I need it but it doesnt support editing.

Forms Data Controls :: Removing Rows From Gridview?

Feb 18, 2010

I have a Gridview which is populated with data based on the selection of dropdowns in a web form. Once the gridview is displayed on the page the user has a "Print" button that will print the gridview. I need to allow the user to remove rows from the gridview prior to printing. I do not want to remove the data from the database, only from the displayed gridview.

I've added a column to the Gridview that has a checkbox which appears next to each row. The header of this column reads "Exlude". If the user checks a box next to a row then this row should be excluded from the printed gridview.Totally new to gridview .. don't know where to go from here.
