Mar 26, 2016
I am trying to get access the elements inside gridview by validating this requirement: if checkbox is checked then 1) Role must be selected from the dropdown 2) And the Title textbook must be filled. I am getting this error now:
Error: Sys.WebForms.PageRequestManagerServerErrorException: Object reference not set to an instance of an object.
JS
<script type="text/javascript">
function validate() {
var flag = true;
var gridView = document.getElementById('<%= gvTest.ClientID %>');
for (var i = 1; i < gridView.rows.length; i++) {
I have gridview in my page that users can edit their data in gridview... and in this gridview I define label that I want when users click on Edit button it change label3.text:
I have a dropdownlist outside the gridview control. My griview control also have dropdownlist in the first column. I want to populate the dropdownlist inside the gridview control for all rows when the selected item is changed in the outside dropdownlist.
I have a label in a gridview where the text is set to <%Bind("lname")%> . I want to make it say thiis <%Bind("lname" + "fname")%>. I've been having a hard time making .net do this. I also want to add a "," or some other unrelated caracter?
I have a GridView inside a repeater, and for all the GridView events such as ItemDataBound, etc. I can't just use the same because it doesn't recognize it. I know I have to use FindControl and type in the ID, but how?
In datalist, I hve populated Grdiview according the Category Id. Inside Gridview , I hve checkboxes. Now i want to get the selected checkboxes names to be insrted into the database. how to get access of those checkboxes inside of Gridview.
I have create one user control of personal details, and write the geting data from database method and Load the entities in respective field,then how to bind user control in gridview and how to accecc Id of user control in aspx page.
Basically as the title of this thread states, I have a FormView that has a GridView inside it and my ObjectDataSource that populates this grid cannot access the Grid.
The Control Id needs to be the name of the Grid I want to access, however through the 'wizard' the Control parameter drop down cannot 'see' the grid I need, only the FormView that is in.
I have tried numerous ways to get round this and am struggling now..
I've tried the following...
ControlID="FormView.GridView1"
ControlID="FormView.FindControl("GridView1")
ControlID="<%= GetNameOfGrid %>"
and numerous other attempts that also failed that I now cant remember...
I have a GridView, the first column it's a RadioButton template and the second it's a DropDownList Template, the number of rows depends on the user, I mean they are not static. I'm using the following JS function to get the row selected with the radiobuttons:
[Code]....
With this function I know which RadioButton was selected, now, I would like to get the DropDownList value or text of the selected row, I know I have to loop through every DropDownList to get an array of controls, but since they are something like ctl00_ContentPlaceHolder1_GVProducts_ctl02_DValsDropDown, I just don't know how to achive this through JS.
In ASP.NET, I can get the selected index of dropdownlist using:
var dropdown1 = document.getElementById('dropdown1');But I want the selected index of that dropdownlist, which is present INSIDE a GridView.How to get that using JavaScript?
I have a user control (ascx) which contains a control (hidden field). In the page_load event of ascx, i have the below code:
HyperLink.Attributes.Add("onclick", "JavaScript:return AccessControl('" + hdnField.UniqueID + "');"); Note: The hidden field resides in .ascx file.
I want to access this hidden field at runtime and i have the below javascript function in aspx page that loads the usercontrol.
function AccessControl(hdnFieldId) { var ctrl = document.getElementById(hdnFieldId); alert(ctrl);
I am getting 'null' value in the alert. I tried using 'ClientID' and 'this' instead of 'UniqueId'. I am wondering why this is not working. I am using .net 2.0.
I need the ability to check a box and then store or remove the text of the checkbox clicked to my sql server database. see my code below that is written in vb.

I have Gridview with Dropdownlist which contains data as {select,1,2,3} .Gridview contains multiple rows of data.Submit button is also on form but outside gridview. If any of the rows of gridview dropdownlist contain value as "Select" and click Submit button ,give message as "Please select value". I want to do this stuff using javascript.
I have a Gridview X in which there are 6 columns(5 template columns that are text boxes and 1 bound field). The user has the option of changing the value in the text boxes annd saving them. There is one more GridView Y that displays DB values(all 6 columns are bound fields). Initially X will show the values that being shown in Y, and when user changes the values in Y,he should be able to save it. If we are trying this using OnTextChanged event of asp:Textbox, there is a postback everytime the user makes a change in any of the textboxes. Instead i want it such a way that all the changed values should get concatenated together and should be sent to the DB.
