I'm learning ASP .NET 2.0. I have a question about the DataGrid (gridview) component. I am working on a simple project where I would like to have a textbox where a user can update hours. Is it possible for every row to have a text box there so anyone can change several hours for each row and save them all at once? That way, no one would have to click edit, and then update for each row. This is the only field editable on this page. Thanks for you input.

Also, I would like to have concurrency to be able to still be used.

yes u can do it by custom code.
dont use the update option of gridview. place a button in the page and in
button clik u can write sql query to insert values in each row to dbase by looping thru the rows in the gridview.. u can ,make use of SqlTransaction to insert all the records in a transaction.
foreach(GridviewRow gv in Gridview1.Rows)
{
// write code for inserting values into database from each row
}

Ok, from there, how would you have that one field editable via a non-read only text box?
|
|
|
|

could u explain?? place textbox in templatefield of gridview. then u can edit..

Yes sorry , I want the user to be able to make a bulk edit as it were. The gridview way that I know, you have to edit one row at a time by clicking the edit button. Is there a way to make all of the textboxes editable or will your suggestion work?

I have an System.Drawing.Bitmap object in memory that I have generated. I need to display this without writing the file to disk or uploading to a database somewhere. Normally I know I could write a binary stream using a Response object, but that is not available to me as I am doing this as a webpart, and all I have available is a HtmlTextWriter.
So I have a method like
<br />
public Bitmap createGraph() {<br />
}<br />
<br />
<br />
protected override void RenderChildren(HtmlTextWriter writer) {<br />
base.RenderChildren(writer);<br />
Bitmap graph = this.createGraph();<br />
}<br />
Thanks in advance.

The only way I know of, is to do a binary write, which only works if you set the mime type and all you send is the image ( not embedded in the page with other things )

I am displaying other elements on the page as well. Do you think the only way is to ship the Bitmap to a database as jpeg, and then read it back? Seems slow and counter intuitive to do it that way?
Ideas?
thanks

No, the only way is to have the image in your file system. So, your best bet is to store image paths in your DB instead of the jpeg data.

You can't do that. The browser will get the image in a separate request. You can't send it in the same request as the page.

Now I have spendt several days without finding a solution to my problem. I almost wish I still coded in ASP or PHP, this was easy in those languages. I have a product webpage where users can view product data for several products. And the users can aslo make changes to the selected product, change price, length and description. For selecting product I'm using a dropdownlist and a for saving data a submit button. As you see in the code below, I can't get the user entered data back from the page. The Page_Load event reload the textbox with data from the database on every reload of the page. Is it possible to construct a page that let me save the user entered data back to database, and not overwrite the text in the textbox on every reload? The code below is a simple, working version of my problem. The line "string sNewText = txtShort.Text;" should returne the userentered data, but it don't.
------------------------------ Design/Html-code ----------------------------------------
Choose product: <asp:dropdownlist id="ddlProductList" autopostback="true" runat="server">
Short text:
<asp:textbox id="txtShort" textmode="MultiLine" enableviewstate="true" runat="server">
<asp:button id="btnSave" runat="server" text="Lagre" onclick="btnSave_Click">
------------------------------ Code behind ----------------------------------------
protected void Page_Load(object sender, EventArgs e) {
int iIndex = 1;
if (ddlProductList.SelectedItem != null)
iIndex = Convert.ToInt32(ddlProductList.SelectedItem.Value);
if (!Page.IsPostBack) {
ddlProductList.DataSource = ProductManager.ProductsAll();
ddlProductList.DataTextField = "Title";
ddlProductList.DataValueField = "Id";
ddlProductList.SelectedIndex = iIndex - 1;
ddlProductList.DataBind();
}
Product productItem = ProductManager.ProductDetails(iIndex);
txtShort.Text = productItem.ShortText;
//txtShort.DataBind();
}
protected void btnSave_Click(object sender, EventArgs e) {
//string ret = Request.QueryString["txtShort"];
string sNewText = txtShort.Text;
}

You gave code to load the textbox in the Page_Load event which causes to lost the data. Is this the problem? Sorry if I misunderstood the problem

You should only do this once, i.e. when !IsPostBack.

I found the solution for my problem. I had to move the code for reading the selected products data/text from database into the Dropdownlist's "selected(?)"-event.

Hi,
My code looks follows for the asp:Wizard control:
<WizardSteps>
<asp:TemplatedWizardStep runat="server" ID="MyTemplatedWizardStep">
<ContentTemplate>
My Templated Wizard Step<br />
<br />
</ContentTemplate>
</asp:TemplatedWizardStep>
<asp:WizardStep ID="WizardStep3" runat="server" StepType="Complete">
Complete Wizard Step
<br /><br />
<asp:Label ID="Label1" runat="server"></asp:Label><br />
<br />
<asp:Label ID="Label2" runat="server"></asp:Label>
</asp:WizardStep>
</WizardSteps>
The button displayed on the TemplatedWizardStep page says "Finish". When I add my own own custom button in <CustomNavigationTemplate> then I am not sure what the CommandName property must be set to, because if I make it MoveNext then it doesn't function the finish button because I have an event handler with OnFinishButtonClick. It does not fire if I have my own button here.
Please can someone advise.
Thanks

I want to show a popup window on while clicking a link button .i want to pass the url of the popup window and also the id of each record while Databinding.the code which i used as follows.
Javascript as follows
function openWindow(url) {
window.open(url,'Calendar',
'width=500,height=400,left=200,top=250');
}
Link Button Postbackurl Code as follows
PostBackUrl="javascript:openWindow('<%# Concatcolumns("UserDetails.aspx?id=",DataBinder.Eval(Container.DataItem,"ID"))%>');">LinkButton
Concatcolumns Function as follows
public static string Concatcolumns(object obj1, object obj2)
{
return Convert.ToString(obj1) + Convert.ToString(obj2);
}
My Javascript code and Concatcolumns functions are correct only problem in my Postbackurl code.what is wrong in that.while page loading i want to bind each record id along with the popup window javascript.

|

Every thing seems ok. May be the PostBackUrl property makes the problem. Try an 'a' tag instead of LinkButton.

What does the generated code look like?
Why do you concat the url using server code, when you can just as well put it in the markup code:
PostBackUrl="javascript:openWindow('UserDetails.aspx?id=<%# DataBinder.Eval(Container.DataItem,"ID") %>');"
