Forms Data Controls :: Cannot Repopulate / Filter Datagrid With User Entered Value From Text Box
Feb 18, 2011
I have a Datagrid control which is populated with data from an Access database when the page loads - a simple 'Select *' command. This page also contains a text box and a button, the idea being that the user can then filter the data by entering a value in the text box and clicking on the button to pass the new parameter to the datasource.
However, I cannot get this to work, I know it has something to do with 'IsPostback', but I am at a loss. I have tried variations of the following in the code behind page but to no avail.
I dont know whether this simple task or not, but I tried to search in google but couldn't find anything.
I've a asp.net form and user enters some data in the text boxes provided. Whenever user submits the form, browser will save that form data. I don't want this form data to be saved in browser. How can I restrict the browser saving this form data without touching the browser settings?
Application is developed using asp.net and normal text boxes are used here.
I have an ASP.Net UpdatePanel that updates on a timer. Within the UpdatePanel and nested in a GridView, I have a TextBox that the user enters a value in with a submit button. Everything works fine, except if the user does not submit the value before the timed interval, the text is removed from the TextBox. Is there a way to persist the user entry into the TextBox between updates? Is there a better way of doing this?
I am developing a page where i have a grid in content page (inherited from master page) which i am populating using DATASET in code behind like this here is the aspx.
As you can see i have some bound fields and one template field called "txtValue" which is the only input in gridview. Now what i want is when user input the value it should check the FACEVALUE and see if the entered value is not above the FACEVALUE and then need to Input value - FACEVALUE and result should be displayed in REMAINING field which is also a template field as label control.
I'm trying to create a Formview in ASP.net 3.5. The underlying SQL Server table does not have an identity field based Primary Key. The primary key is a 4 character user entered field. I have created the form and all looks good but I get the following error message when I try to insert a record
Could not find a row that matches the given keys in the original values stored in ViewState. Ensure that the 'keys' dictionary contains unique key values that correspond to a row returned from the previous Select operation.
I thought ViewState was supposed to resolve the issue. I have viewstate enabled on the page and the formview but that doesn't seem to make a difference.
How can I create a form view with a user-entered text field as the primary key and get the b.... thing to work?
I had called the data from query to data table and now i have a gridview in which i am using one datalist and 2 text boxes and and reming coloumns are bounded iahve to assiaign them values which datatable have either null or any value.
I want to be able to take data entered in a certain text box in a web form and use it in another web form for example: upon clicking a button I want to redirect to another web form and that a text present in the first web form box textbox will automatically appear in a text box on the second web form can someone get me started on how to do that?
i want to display a multiline text in a datagrid i insert the text in a textbox outside the datagrid.
the textbox wraps the text if it doesnt fit to the textbox length.then i push a button and insert that text in a database. then i want to display this text in a datagrid.i use two options in a label or in a textbox in a templatecolumn but with the textbox <asp:textbox ID="textbox1" runat="server" style="overflow:hidden" Font-Size="15px" BackColor="#FFFFC0" TextMode="multiline" Width="750px" Wrap="true" borderstyle="None" BorderWidth="0" Text='<%# Databinder.Eval(Container.Dataitem,"text_caption") %>'></asp:textbox>
i receive only the first two lines
and with the label <asp:Label ID="Label112" runat="server" BorderStyle="None" Width="750px" BorderWidth="0" Text=' <%# Databinder.Eval(Container.Dataitem,"text_caption") .ToString.Replace(chr(13),"<br />") & "<br/>" & "<br/>" %>' ></asp:Label>
if the text is too big without an enter(that text wraps in the outside inserting textbox) then the datagrid width becomes too big although the text is diplayed normal with new lines so in the datagrid i have much space without characters the textbox that i use to insert new text is here <asp:TextBox D="tbox_text_caption" runat="server" Height="232px" Style="left: 400px; position: absolute; top: 8px" MaxLength="750" TextMode="MultiLine" Width="752px" Wrap="true" TabIndex="5" BackColor="#FFE0C0"></asp:TextBox>
I have a FormView and the SELECT statement I have is as follows:
SelectCommand="SELECT [UserName], [Full_Name_1], [Full_Name_2], [Email], [Address], [City], [State], [Zip_Code], [Home_Phone], [Cell_Phone] FROM [Homeowners] WHERE ([UserName]='<%$ User.Identity.Name %>')"... but it results in the FormView disappearing from the web page. Note: at the top of the page, <%= user.identity.name %> displays the name fine, so user.identity.name does contain the info I'm looking for.I am trying to figure out how to correctly format the SELECT filter to feed user.identity.name to the SELECT statement as a filter. ... or if there is an alternative way.
I have a form where users enter information in a multi-line text box. This could be anything, such as bullets, carriage return line feeds, etc. Think of anything that you might copy and paste into a multi-line text box from Word Pad, or Word. I then store this information into a SQL Server NText field.When I retreive this information, I need to display it as the user entered it into the text box field into a Literal or Label control (or something else if there is a better alternative) to display it. Problem is that when I display this text into the Text property of a Literal control everything is jumbled and all characters (bullets) are lost, no carriage returns, etc. One big mush of stuff. If I display this information in the Text property of Label control, I get the bullet characters, but no carriage returns
After hitting the insert button the insert stored proc is run. if the record already exists then stored proc returns a specific value.I need to refill the details view textboxes with the values the user typed in.I am using the ItemInserted event handler.I seem to reference the control okay but the text doesn't change...even when I replace the command.parameter to just a literal text like "test".
TextBox tNPA = DetailsView1.FindControl("InsertName") as TextBox; tNPA.Text = command.Parameters.Value.ToString();
So what am I missing. I also tried a detailsview1.databind() before and then tried after the above line and still no luck.
