Forms Data Controls :: Gridview Link Button Control Click Event?

Sep 28, 2010

I have Web page that uses LinkButton control inside Template Fields of Gridview.I am trying to work on LinkButton Click event and trying to preserve the Value of LinkButton that user click, and based on that value, i want to refresh tha page data.

I used CommandName and CommandArgument property of Linkbutton, but i can use that property only in GridView_RowCommand method by checking e.CommandName expression. But the problem with that Gridview_RowCommand event fire after all other page_load activity. So the value never used in the page_load event to refresh the data in all other control.I also tried to use OnClick Method, Session variable and Hidden variable. but when i run Response.Redirect method from Gridview_RowCommand, it clear all the Session and Hidden variable values. also tried (Response.Redirect(,false)) method but never got success.

Forms Data Controls :: Gridview RowDataBound Event - Set Default Value

May 17, 2010

When a Gridview row is in edit, I need to default an empty textbox to today's date. I am close, but the defaulted date is is not saved to the database. I can key in the date and the date is displayed and saved to the database. Even more interesting:

1. The date is defaulted to - 5/17/2010
2. If I erase the month and key the "5" back in the data is not saved.
3. If I erase the month and then change the month to "6", the data is saved to the database. If any value is changed in the date the save works.

Forms Data Controls :: GridView's RowDataBound Event Fired Twice?

Apr 20, 2010

I have a very simple page, just some buttons and one GridView on it. The logic is a user click the QUery button,then the button click event was trigured to populate the gridview with data queried from database via LINQ. for a user friendly interface, in RowDataBound event, I visit every row, change a boolean value into checkbox represention. But it seem that the RowDataBound run twice, because the checkboxs were inserted twice for every row in one cell. so why? the source code snippet as follow:

protected void btnSelect_Click(object sender, EventArgs e)
RetiredEmployeeDataContext db = new RetiredEmployeeDataContext();
GridView1.DataSource = db.ENTUserAccountSelectAll();//userAccounts;
protected void GridView1_OnRowDataBound(object sender, GridViewRowEventArgs e)
if (e.Row.RowType == DataControlRowType.DataRow)
CheckBox chkActive = new CheckBox();
chkActive.Checked = ((ENTUserAccount)e.Row.DataItem).IsActive;
chkActive.Enabled = false;

Forms Data Controls :: Why Wasn't GridView's RowDataBound Event Fired

Apr 21, 2010

Why wasn't my GridView's RowDataBound event fired? I have a masterpage on whick i have a query button, and I have a content page on which i have a customized GridView(named cgvEmployees,derived from GridView). The logic is when user click the button, the button click event triggered that search the underlying database and populate the GridView.

Everything runs great except that RowDataBound event isn't triggered. Because I have to change some cells' representations in RowDataBound event handler. I have surfed so much pages to find the answer but failed. Below is what i have already done:

1. set the autoeventwireup to true;
2. i have a cgvEmployees.bind() sentence in the button click event handler;
3. i have OnRowDataBound="cgvEmployees_OnRowDataBound" in the content page GridView tag attribute

by the way, the database query is coded by Linq Dynamic Query (please google 'dynamic Linq').

void Master_QueryButton_Click(object sender, EventArgs e)
RetiredEmployeeDataContext db = new RetiredEmployeeDataContext();
NameValueCollection nvcQueryKeyValue = getNVCQueryKeyValue();
Expression<Func<RetiredEmployee, bool>> searchPredicate = getLambdaExpr(nvcQueryKeyValue);
IQueryable<RetiredEmployee> retireds = db.RetiredEmployees;
Expression expr = Expression.Call(typeof(Queryable), "Where",
new Type[] { typeof(RetiredEmployee) }, Expression.Constant(retireds), searchPredicate);
IQueryable<RetiredEmployee> query = db.RetiredEmployees.AsQueryable().Provider.CreateQuery<RetiredEmployee>(expr);
List<RetiredEmployee> employeeList = new List<RetiredEmployee>(query);
List<RetiredEmployeeEO> employees = new List<RetiredEmployeeEO>();
foreach (RetiredEmployee employee in employeeList)
RetiredEmployeeEO employeeEO = new RetiredEmployeeEO();
cgvEmployees1.ListClassName = typeof(RetiredEmployeeEOList).AssemblyQualifiedName;
cgvEmployees1.LoadMethodName = "LoadFromQuery";
protected void cgvEmployees1_RowDataBound(object sender, GridViewRowEventArgs e)
if (e.Row.RowType == DataControlRowType.DataRow)
//Add the edit link to the action column.
HyperLink editLink = new HyperLink();
if (((BasePage)this.Page).ReadOnly)
editLink.Text = "View";
editLink.Text = "Edit";
editLink.NavigateUrl = "employee.aspx" + EncryptQueryString("id=" + ((RetiredEmployeeEO)e.Row.DataItem).ID.ToString());
//Add checkbox to display the isactive field.
CheckBox chkActive = new CheckBox();
chkActive.Checked = ((RetiredEmployeeEO)e.Row.DataItem).liveOrDead;
chkActive.Enabled = false;
if (((RetiredEmployeeEO)e.Row.DataItem).gender.Equals((byte)1))
e.Row.Cells[2].Text = "Male";
e.Row.Cells[2].Text = "Female";
if (((RetiredEmployeeEO)e.Row.DataItem).retiredOr.Equals((byte)1))
e.Row.Cells[14].Text = "Retired1";
e.Row.Cells[14].Text = "Retired2";
if (((RetiredEmployeeEO)e.Row.DataItem).birthday.Equals("1753-01-01"))
e.Row.Cells[3].Text = "";
if (((RetiredEmployeeEO)e.Row.DataItem).dayToEmployed.Equals("1753-01-01"))
e.Row.Cells[6].Text = "";
if (((RetiredEmployeeEO)e.Row.DataItem).dayRetired.Equals("1753-01-01"))
e.Row.Cells[7].Text = "";
if (((RetiredEmployeeEO)e.Row.DataItem).dayParty.Equals("1753-01-01"))
e.Row.Cells[13].Text = "";
if (((RetiredEmployeeEO)e.Row.DataItem).daytoassign.Equals("1753-01-01"))

Forms Data Controls :: Access GridView PageIndex In Rowdatabound Event?

Feb 5, 2010

How do I access GridView Page Index in RowDataBound event? I am assigning PageIndex to hyperlink on the gridview, for this I was planning to use "GridView1.PageIndex" in rowdatabound event. Problem is when I got second page in gridview (10 rows per page), the first row in the page shows page index as "0" and from second row it becomes 1. And if I goto third page, the first row in the page shows page index as "1" and from second row it becomes 2.

Forms Data Controls :: Rowdatabound Event Of A Gridview Loses Its Value While Editing?

Feb 5, 2011

I have a Gridview with edit and update feature enabled. It displays the data correctly but when I click on the Edit linkbutton(to edit the data), I get the error "Object reference not set to an instance of an object".

I tried debugging and found that the row which I click (say editindex is 1) loses its value. I could identify this while debugging the code, when the code flow moves to the rowdatabound event, the label (or for that matter any control in the rowdatabound event) shows a null value and eventually errors out.

I am unable to figure out as to why the control specified in the rowdatabound event loses its value when editing. Note: The lost valueow data is the one which I tried editing.

I am attaching the code which I have written for the rowdatabound event.

Forms Data Controls :: Database Updates But Gridview Doesn't After Custom Button Click Event?

Feb 8, 2010

So I followed Scot Mitchell's tutorial from on adding a checkbox column to be able to select multiple entries and delete them with the click of a button. When I make my selection and click the button it works on the database end, as the desired entries are deleted. However, the entries remain on the page after it reloads. if I refresh the page it's updated properly but I'd like it to automatically update after the button is clicked.

Also, I tried his method for adding check/uncheck all buttons to the top of the gridview and they don't seem to be working either.

Here's the code behinf from the gridview page:

Forms Data Controls :: Create Textbox Dynamically In GridView And Retrieve The Value In Button Click Event?

Mar 24, 2011

I have a dropdownlist("ddlTemplate") control and a gridview("gvPlanning") control with 1 BoundField column, 1 TemplateField column and remaining columns will be generated dynamically from database.In TemplateFiled Column i have 3 image buttons viz: Edit, update and cancel.Gridview will be populated based on the selecteditem of dropdownlist.

if i click on edit imagebutton, i need to add textboxes dynamically in all the columns of that row except first 2 column. And if i click on Update imagebutton i need to retrieve the textbox values.we can add template field column for textboxes also, but why i am sticking to this method is.. the number of columns changes depending on the selecteditem from the dropdownlist. Eg: If i select india from dropdownlist the number of columns in the gridview would be 4 and if i select UK from dropdownlist the number of columns would be 9 likewise.
