Forms Data Controls :: Make Specific Cells In A Dynamic Gridview Clickable And Capture The Cell Info Before Redirecting

Aug 3, 2010

I generate dynamic grids based on a count value returned from some DB tables. the code for it goes like this : I give and Id to each grid that is generated.

if (myDataList1.Count >= 1)
for (int i = 0; i < myDataList1.Count; i++)
//retrieving the exact i count from pageload
ViewState.Add("newCount", i);
//creating the dynamic grid with its corresponding gridview properties.
grvDynamic = new GridView();
grvDynamic.ID = "GridView" + (i+3);
grvDynamic.AutoGenerateColumns = false;
grvDynamic.RowCreated += GridViewRowCreated;
grvDynamic.RowDataBound += grvDynamic_RowDataBound;
//adding bound field columns to retrieve data from stored proc
BoundField metric = new BoundField();
metric.HeaderText = "Goal ";
metric.DataField = "metric";
BoundField mtd = new BoundField();
mtd.HeaderText = "MTD";
mtd.DataField = "value_MTD";
BoundField goal = new BoundField();
goal.HeaderText = "Tier Level Achieved";
goal.DataField = "value_goal";
goal.HeaderStyle.Width = Unit.Percentage(10);
BoundField you1 = new BoundField();
you1.HeaderText = "Month End";
you1.DataField = "firstLevel_you";
BoundField you2 = new BoundField();
you2.HeaderText = "Month End";
you2.DataField = "secondLevel_you";
ButtonField singleClick = new ButtonField();
singleClick.CommandName = "clickHyperlink";
singleClick.Visible = false;
BoundField metricId = new BoundField();
metricId.HeaderText = "Metric Id";
metricId.DataField = "metricID";
metricId.Visible = true;
//binding the gridview to data.
grvDynamic.DataSource = data;
grvDynamic.Columns[5].Visible = false;

protected void grvDynamic_RowDataBound(object sender, GridViewRowEventArgs e)
//this basically gets the metric Id's of rows with the ishyperlink flag set to 'Y'. I need to make these particular cells clickable var isClickable = (from md in myDataList3 where md.IsHyperLinkFlag == 'Y' &&

md.value_MTD != null select md.metricID).ToList();
if (e.Row.RowType == DataControlRowType.DataRow)
// Get reference to button field in the gridview.
LinkButton _singleClickButton = (LinkButton)e.Row.Cells[5].Controls[0];

if (isClickable.Contains(Convert.ToInt32(e.Row.Cells[6].Text)))
e.Row.Cells[1].Style["cursor"] = "hand";
e.Row.Cells[1].Style["color"] = "blue";
e.Row.Cells[1].Style["textdecoration"] = "Underline";
e.Row.Cells[1].Attributes.Add("onClick", "window.location ='../HeaderPages/page2.aspx' ");

This code works perfectly fine , depending on the ishyperlink flag in the database...specific cells in the grid are made clickable and then redirected to page2.aspx My Issue: I need to capture which specific cell in which specific grid the user has clicked. store some information in sessions based on the cell clicked and use that information in page2.aspx.

i have gridview and im displaying the employement history of employee.and im providing a hyperlink in empid to open employee page with update mode that user can update the record.i have an issue here.only if the employeeresigned = "N" empid should be hyperlink, if its "Y" it should not be a hyperlink.

SortExpression="empid"> [code]....

am wondering how to do this

1) shall i replace all the linkbutton with label if the resignedstatus = "Y"

- how to do this? 2) or shall i make the empid as boundfields instead of templatefields and write code on rowbound...with checkin that

if resigned =
"Y" then
e.Row.Cells(0).BackColor =

e.Row.Cells(0).Attributes.Add("onclick", "empDetails_disp")

e.Row.Cells(0).Attributes.Add("class", "statusclass")


in this case i can use only javascript function for

e.Row.Cells(0).Attributes.Add("onclick", "empDetails_disp")

this statement? or can i directly call my empdetials_disp function in my aspx.vb page...

Forms Data Controls :: Making GridView Cells Specific?

Apr 9, 2010

I have a gridview that has both a select and an update statement. One of the cells is a date cell, and the other is for numerics only. Is there a way I can do this? At the moment, anything can be keyed into the cells and this results in an error as my update stored procedure expects a date value and a numeric value respectively.

Data Controls :: Validation For Dynamic Gridview Cells

Dec 8, 2013

In my gridview i have

I have a dropdownlist with tables. if i select the table, based on the columns the gridview displays.

One table contains 9 columns and other contains 40 columns... for example....see the below.

Insert/Edit    RoleUID   RoleID    Role   Desc   ....etc columns

Here RoleId, role are mandatory fields... i am making those two with "*" red color. but if i click on the "INSERT" then i need to get a alert msg that the roleid is mandatory.. you should enter in interger value, and if "role" is null then same like "Role is mandatory... plz enter character value"

I don't have any template fields in the gridview. i make autogeneratecolumns=true in my grid.

I need validation for the dynamic gridview cell... where there is no columns fixed...

I used the below code ... for INSERT 

for (int j = 3; j < cellCount; j++)  {

Forms Data Controls :: Dynamically Add A Button With An Eventhandler To A Specific Cell In Gridview

Mar 10, 2010

I am banging my head with gridview at the moment. There's a problem I just can't get my head around. I'd be very greatful for any advice given. I have a function that creates a DataTable with three columns and four rows. In each of the cells I set the text to a random number through RowDataBound event. I would like to just make the cell clickable and have a code-behind function that gets the position of the cell (column, row) and the value of the cell when the user clicks it.

Forms Data Controls :: Dynamic Tooltip For Gridview Cell

Feb 24, 2010

My GridView rows have a field for a server timestamp when a person entered in a particular state(like idle). I want to show the time elapsed since the person has been in that particular state. That I want to show as a tooltip when mouse is hovered over the cell and time elapsed calculation I want to do on client side only without a roundtrip to the server. In RowDataBound event of the GridView I add functions to the show and hide the tooltip by following some examples on the web. In the JavaScipt function, I calculate the time elapsed. But it works first time but not after that somehow and I get a JScript error "Microsoft JScript runtime error: Function expected." on this line:

document.getElementById("td0").innerText = elapsedpretty(timeInState);

My GridView is inside a user control which is used as a ASP.NET web part and my web part zones are inside ASP.NET UpdatePanel. Could it cause a problem?

Forms Data Controls :: How To Make A Cell On A GridView To Be Link On A Page

Oct 27, 2010

im just trying to use this answer, but im getting an error on my page:

"A field or property with the name 'returnantID' was not found on the selected data source."

Im not really sure what the "returnantID" is but it appears my page isn't liking it, not sure if i was sopposed to cswap it out for some other data or not.

This is my current gridview:

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" GridLines="None"
<asp:BoundField DataField="ProductName" HeaderText="ProductName"
SortExpression="ProductName" />
<asp:BoundField DataField="Price" DataFormatString="{0:c2}" HeaderText="Price"
SortExpression="Price" />
<asp:BoundField DataField="Length" HeaderText="Length"
SortExpression="Length" />
<asp:BoundField DataField="Engine" HeaderText="Engine"
SortExpression="Engine" />
<asp:BoundField DataField="Colour" HeaderText="Colour"
SortExpression="Colour" />
<asp:BoundField DataField="Description" HeaderText="Description"
SortExpression="Description" />

would just like the ProductName to link to the corresponding products page(using its Id)

p.s this is what i tried:

<asp:HyperLinkField DataNavigateUrlFields="returnantID" DataNavigateUrlFormatString="Details.aspx?id={0}" DataTextField="ProductName" NavigateUrl="Details.aspx" />

**Update** I changed the "returnantID" to "ProductName" which turned the name of my product into a link but clicking that link gave me this new error:

Input string was not in a correct format.

Forms Data Controls :: How To Make A List Of Data Clickable.

May 27, 2010

My doubt is how to make a list of titles of the news contained in a database. And this list each of the titles when clicked is redirected to a page where you will be able to view the news in full (Title, Body, Author).

What I got:

- A database containing a table with the news, every news is associated with an identification code (ex: "ID").

- A page where you will make the listing. (Ex: site / listofnews.aspx)

- I have a page that uses the method "querystring" to know what is the primarykey the news. (Ex: site/shownews.aspx?ID=12345, where "12345" is the primarykey of the news. Once it knows what is the primarykey of the news in the database, it loads each of the fields of the page (news.aspx) with
the news, this part is working ok.

- The data is retrieve using the Linq, so I receive a List of "News", the class "News" as ID, Title, Body, Author.. My doubt is how to make the listing clickable.

In php I used this method (make a list of html links, in each link the href field is changed so that the tag "id" coincides with the news):


How do i make the same with

Forms Data Controls :: Adding Dynamic Controls Into Table Cells?

Feb 21, 2011

There are two fields and a button :

1)text box for the caption.

2)drop down list to select the control to be added.

3)button is an ADD button .

when the "ADD" button is clicked the text entered in the "caption" text box has to appear in the first cell of the first row in the table and the control selected from the dropdown list has to be added to the second cell of the same row. similarly many such captions and controls have to be dynamically addded to the successive rows of the table as per user selection ( note: the previously selected control and caption label must persist on furthur selections .

how do i go about the adding controls and the text into the table part ?

Web Forms :: Hide Specific Row Cell From GridView Based On Some Condition

Aug 3, 2012

I have a gridview which displays a list of submittted applications with a column that contains an edit link.

<asp:TemplateField HeaderText="Status">
<asp:LinkButton ID="lnkBtnEdit" runat="server" CommandArgument = '<%# Eval("appID")%>' Text = "Edit" OnClick = "editApp" />

I want to hide the link button if the status (value 1 or 0) of the form is set to 1. Here is the code I am trying to use.

Protected Sub gv1_RowDataBound(sender As Object, e As GridViewRowEventArgs)
If e.Row.RowType = DataControlRowType.DataRow Then
'get the cell cell value
Dim status As Integer


I think my mistake lies in getting the status value (as it ouputs 0 for every application).
