Forms Data Controls :: Query Excel File And Display On Datagrid
Mar 25, 2011
successfully querying an excel file the problem is when im about to display the data im worried that even the rows from excel that do not have actual data is being pulled is there any way that i can query only the rows that contain data
I need to export SQL query results to an Excel file.
I use the following code to do it.
Works fine for majority of the cases. There is a column called Description in the query results which is of type nText in the sql database. This can have lengthy data ( couple fo paragraphs) . When the number of charcters are large only the first portion of the data is showed and it trims the rare portion. how I can avoid this? Or any efficient code example on how I can do this in a different manner
We have the requirement to export the data from the grid excel. We can't install the Excel on the server. The excel generated need to be in the printable format. The excel generated needs to have custom headers, footers, repeatble rows, columns and landscape / portrait orientation style.
I'm building a User Control that will allow a user to select input parameters, run a query and then view the results in a GridView control. That part is obviously very easy. However, I've been asked to also provide the option of viewing and/or printing the data in a PDF, Excel or CSV file format.
Are there any .Net 2.0, built-in classes that allow for exporting and printing data in these formats in Visual Studio 2005?
A couple of years ago, I worked on a website that offered this functionality in Crystal Reports, but on this particular assignment, we aren't currently using Crystal - I'm not at work right now, and I can't remember if we're running the "Standard" or "Enterprise" edition of Visual Studio.
on use this code on button click event.. file is generating but when i use same file for import in to database It gave me Error : External table is not in the expected format. For prob. of Format Type for Excel.
'm not sure if this is the right forum, but I couldnt find one for linq related questions.I have the following problem. I have four tables, One with users, one with projects, one with the users and the projects they are in (joinProjectTable) and on table where the users can fill in there worked hours for a certain project. These hours are filled in on a daily base. Now every month there is going to be created a report on the workedHours table so there is visible which user has entered how many hours for a certain project. On this report there is gonna be a billing for the company where for the hours are worked. This is the easy part, the hard part is the following.
companies also want to have a list of users that didn't entered any hours for that particular month for a particular project. So I have to write a linq query that would look in the joinprojecttable to see which users are joined to which projects, and than with that join it should look if that particular combination (user+project) is in anyway entered in the workedhourstable for that particular month. If not this has to be shown in the datagrid, for every user that isnt in the workedhourstable for that month. So it should be a certain NOT query, but I can't seem to figure it out.does anyone have any idea to accomplisch this in Linq2Sql? I'm using VB instead of C#.
I'm trying to display a list of Excel files that are stored in multiple folders in adatagrid but the .GetFiles part of the routine in my loop only gets the very last excel file rather than all that meet the criteria. Below is the code I've been working on for several days. This is the first time I have tried to use a "For next loop," and I am having much trouble with this. Using the same loop code posted I was able to verify that the loop was working by appending some text into a temporary label.
I have not done this before so pardin this question that I am sure has been asked before. I have a user that asks me to run queries each month and copy & paste the data into a spreadsheet I want to set up the queries in a web page for him to choose, enter the data in the parameters and either show the data in a gridview then export or just export to the spreadsheet direclty to the file name and location of his choice. Using C# Links or code samples would great.
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 datagrid, View details button on the datagrid. If I click on the button, It will redirect to another page with all the details.I have update button and return button on that page. If I click on update, It will update data in the database. If I click on the return button, It will return to previous page which has datagrid but I want the update details in the datagrid. I have a big doubt, how to store that datagrid so that we can retrieve data on return button
I have left menu navigation which is a datagrid. They are linkbuttons. When clicking it, it will display related data based on the value passed from the link. But if the passed value is a specific value, it is not displayed data in the right pane; instead, it will displayed a submenu of the link.
I have a SQL Data Source that displays records after going through the Query Builder and select "Test Query" yet when I save it, go back to the design mode and select View in Browser I get nothing but a blank screen.
I need to read data in DataGridView from one page to display using label in Other Page.I think here using QueryString concept. i cant remember the coding for QueryString and How to get Query string in another web page.Please give the sample coding using C# for me.
I am having a bit of frustration trying to display an image save in a folder after upload in a datagrid. The image path is being return but the image does not displays. When I check the image properties is empty. THis is what I've been trying.
Here is where the image is being save: imagePath = "C:\inetpub\wwwroot\soweb\page_images\image1.png" If I change the path in the database to: page_imagesimage1.png, the image is display in the datagrid.
