I'm trying to add multiple statements to a onclick attribute of a Gridview row:[Code]. Something must be wrong with the way I concat the string 'script' with the statement that makes the row selectable. when the session var is null, then the Page.ClientScript statement goes through and the row will be selectable, but when the session var is NOT null and as a result, the whole statement contains the 'confirm' part, the the confirmation dialog pops up but nothing else happenes upon confirming. What's wrong with the "script += Page.ClientScript.GetPostBackEv..." part?
View 4 RepliesI have a gridview control that extends the default gridview. I have added an attribute called "hiddenSelectedValues" to to the gridview during the "PreRender" event and I have a private variable that points to the value of that attribute.
I have some javascript code that modifies the value of this attribute based on the user checking or unchecking checkboxes in the grid. I have confirmed that the javascript is indeed modifying the value of the "hiddenSelectedValues" attribute by using Firebug to see the change as it happens.
However, once a postback occurs, the grid looses the updated value of this attribute and I am unable to reference get the updated value on the server side.
How do I keep the value of an attribute changed by javascript on postback?
I have a tag:

When you push Gridview delete button, I want to alarm "do you want to delete register" . I searched in the internet and I wrote the code like that.

I am trying to create an event with a gridView and a c# method. So far I am getting this error:
CS1061: 'ASP.contentpage9_aspx' does not contain a definition for 'ImageGridView_OnSelectedIndexChanged' and no extension method 'ImageGridView_OnSelectedIndexChanged' accepting a first argument of type 'ASP.contentpage9_aspx' could be found (are you missing a using directive or an assembly reference?)
Here is the asp markup:
<asp:GridView ID="ImageGridView"
DataSourceID="ImageSqlDataSource"
AutoGenerateColumns="false"
DataKeyNames="ImageID"
OnSelectedIndexChanged="ImageGridView_OnSelectedIndexChanged"
RunAt="Server">
And my c# method:
void ImageGridView_OnSelectedIndexChanged(Object sender, EventArgs e)
{
ImageDetailsSqlDataSource.SelectParameters["ImgID"].DefaultValue =
ImageGridView.SelectedValue.ToString();
ImageFormView.DataBind();
}
I have a requirement something as below.
1. I will click on the EDIT link in one of the grid view row. The row will change to edit mode
2. I will update the values and click update link in edit mode and edit mode closes.
3. At this point I need to capture the datakey of the updated row into some variable
i have a dynamic data layer, i.e every user can add custom fields to database tables, so i need dynamic methods in my application.
i know i can use params to specify a variable number of parameters for a method, but the gridview in asp.net looks for a method with the same fields it is updating, i.e if gridview updates fields :name, age, phone, email(suppose email is a custom field of a certain user i.e it doesn't exit for another), and the object data source calls the update method with signature : (name, age, phone, params object[] custom_attributes) an error is generated that the gridview can not find the method with the signature(name, age, phone, email)
I have created a web app with a gridview that is connected to an sql data source to extract data. The web app consists of two pages (default.aspx and rategrid.aspx). On the default page i have a button that when clicked it displays rategrid page with the gridview data. On rategrid page I also have two buttons (one to go back to default page and one for export to word). When I click the word button, i get error (Control 'GridView1' of type 'GridView' must be placed inside a form tag with runat=server.).I have already looked at references online that reference to put (Public Overloads Sub VerifyRenderingInServerForm(ByVal control As Control) in code for Word button. However, I am still getting the same error.
View 15 RepliesI am using Footer template in gridview for first time..
I am unable to show anything in the footer template with eval() method...
Here is some of my code in the gridview..
<asp:CommandField ShowSelectButton="True" FooterText="Amount" />
<asp:TemplateField HeaderText="ColorCode">
<ItemTemplate>
<asp:Label ID="lblColorCode" runat="server"><%# Eval("ColorCode")%> </asp:Label>
</ItemTemplate>
<FooterTemplate>
<%# Eval("Total")%>
</FooterTemplate>
</asp:TemplateField>
is it possible to have a button that points to a method you have defined in codebehind, that passes in a record from the row as a parameter? for example, id.something like:
<asp:CommandField ButtonType="Image" EditImageUrl="/editbutton.jpg" ShowEditButton="True" OnClick="editRow(int id)"/>
it wouldnt necessarily 'edit' this row. i'd like it to instead load an editable grid corresponding to the id passed.
i am facing a strange problem putting it in short .... i have two grids... i have grid1 and grid2... now based on row click of firstgrid..i wd take d id from cell(0) of first grid and then fill up the 2nd grid based on tht info selected (id) from the 1st
grid .... here is the code snippet :
[Code]....
and here is the codebehind :
[Code]....
now the problem is that : when i click the row for first time it shows into the 2nd grid all fine ...

I've got a GridView, with a TextBox designed in the template field. Im binding values to the textbox from ObjectDataSource.I've attached a textchanged event to the textbox, to capture the rowindex when a particular textbox value is changed by the user.

Maybe this is dreaming, but is it possible to create an attribute that caches the output of a function (say, in HttpRuntime.Cache) and returns the value from the cache instead of actually executing the function when the parameters to the function are the same?
When I say function, I'm talking about any function, whether it fetches data from a DB, whether it adds two integers, or whether it spits out the content of a file. Any function.
In a GridView control ASP.NET
OnRowDataBound="gvTest_OnRowDataBound" followed by
protected void gvTest_OnRowDataBound(....){}
OR
Text='<%# BindMyData(DataBinder.Eval(Container,"DataItem.Price"), DataBinder.Eval(Container,"DataItem.CurrencyID")) %>'
followed by
protected string BindMyData(object price, object currencyID)
{...}
Which one is best in terms of performance and coding best practice?
Is there an equivalent of the GridView.RowDataBound event for the DetailView and FormView controls in ASP.NET 3.5?I need to manipulate data after Selecting it from my database, but before it gets presented to the user. I've read the documentation but I think I've missed something because I can only find FormView.DataBound which is called after the entire control has been data bound. Something like an ItemDataBound event would be what I need....?!?

Got a little dilemma I could use some guidance on. I'm trying to call an Interface method that resides in my Business Layer from within the template of a gridview in the same manner as below:
<%# GetEmployee(Eval("EmpId"))%>
i.e. it reads as follows:
<%# BusinessLayer.IEmployee.GetEmployee(Eval("EmpId"))%>
I'm actually getting the following error:
"An object reference is required for the non-static field, method, or property"
Which makes sense as I haven't instantiated as instance of the Interface. So the queston is how do I do it?
I am having a simple web service method which returns JSON serialized response. The attribute to web method is
[WebMethod, ScriptMethod(UseHttpGet = true, ResponseFormat = ResponseFormat.Json)]
As security of the return data is not a problem, I am Get enabling the HTTP response. On the client (browser) end, my code is as below
[Code]....
Everything works smoothly but occasionally on the web server's event viewer, I see the following error
"Request format is unrecognised for URL unexpectedly ending in /SomeWebServiceWebMethod"
After fiddling through the request headers using Fiddler, I figured out that if I make direct request to the webservice link, contentType header attribute is missing and that is what throws the error. There is a good post by scott guthrie explaining this. I am not able to replicate the issue and not sure what removes the contentType attribute from the request header occasionally.

I have a search page with a GO button. The user enters his search term in a text box, then he clicks on GO, and a Gridview gets populated with database records that match. The problem is this. Suppose there are several pages of data, and the Gridview has page-numbers at the bottom and the user clicks on page 4. He views whatever is on page 4. Then he decides to do another search, this time for some other word. He clicks GO, and the gridview populates, but the page still is page 4 (though for the new data). When he does a new search, I want the gridview to be on page 1. I found a method for gridview called "setPageIndex", but the question is where to do that. Should I set the page index in the GO button code, or in the databound event of the Gridview, or somewhere else? I find that if there are no records, and I do a "setPageIndex", that the program crashes. I also find that it doesn't seem to do anything when I put it in the GO button code.
View 2 RepliesI am new in ASP.NET and I am having a problem in generating the ID of each label that I generate in ListView's ItemTemplate control. I use it like this :
