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 ?
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?
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.
I have seen alot of posts on the inetrnet with the solution to mainatin gridview scroll using an Ajax Update Panel.

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.
I have a set of dataset with different column retrieved from DB. I need to present the datasets in one GridView (or other ListView etc...) without specifying the column_header. It should present automaticly since the GridView is bind to the DataSet.
In additional, I want this GridView to handle multiple rows edit and update the dataset, idealy, show data in textboxs in initially.How could I set the GridView to edit_model without hardcode column_header and textboxs in 'itemtemplate' or filed.
How could I achieve the bulk edit and update, so that I can assign 'mydataview1.table' to the dataset.

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

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.
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.
I bind data to GridView from SqlDataSource. GridView have <19 rows. But i want that all 19 rows are written. If Rows in SqlDataSource are empty it's must be empty in GridView but must be there!
